Hurricane Francine Brings Wind and Rain to Southeast Louisiana

Hurricane Francine brought wind and rain to southeast Louisiana on Wednesday evening.  Francine weakened to a tropical storm after it moved inland.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Francine was located at latitude 30.2°N and longitude 90.6°W which put the center about 35 miles (55 km) west-northwest of New Orleans, Louisiana.  Francine was moving toward the northeast at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 982 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Intracoastal City, Louisiana to the Alabama/Florida border.  The Tropical Storm Warning includes New Orleans, Lake Pontchartrain and Lake Maurepas.

Francine was a Category 2 Hurricane on the Saffir-Simpson Scale at the time of landfall.  The maximum sustained wind speed at that time was 100 m.p.h. (160 km/h).  At the time of landfall winds to hurricane force extended out 40 miles (65 km) from the center of Francine’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of circulation.

The Hurricane Intensity Index (HII) at landfall was 16.5.  The Hurricane Size Index (HSI) was 13.7 and the Hurricane Wind Intensity Size Index (HWISI) was 30.2.  Hurricane Francine was similar in intensity to Hurricane Idalia when Idalia hit Florida in 2023.  Francine was larger than Idalia was.

The center of Hurricane Francine made landfall on the coast of Louisiana south-southwest of Morgan City.  The center passed near a NOAA National Ocean Service Station north of Eugene Island, Louisiana (EINL1).  The station reported a sustained wind speed of 75 m.p.h. (120 km/h) and a wind gust of 105 m.p.h. (169 km/h).  The station reported a surface pressure of 976.0 mb.

The center of former Hurricane Francine passed west of New Orleans.  Francine dropped heavy rain over many parts of southeast Louisiana.  Flash Flood Warnings were issued for several parishes.  A weather station at the Louis Armstrong International Airport received 6.98 inches (177.3 mm) of rain.  A weather station at New Orleans Lakefront Airport reported 4.58 inches (116.3 mm) or rain.  Heavy rain was beginning to fall over parts of southern Mississippi.

Southerly winds were still pushing water toward the coast of southeast Louisiana and the coast of Mississippi.  Those winds were causing a storm surge along the coast.

A Storm Surge Warning in in effect for the portion of the coast from Avery Island, Louisiana to the Mississippi/Alabama border.  The Storm Surge Warning includes Vermilion Bay, Lake Pontchartrain and Lake Maurepas.

Tropical Storm Francine will move between a high pressure system that extends from the western Atlantic Ocean to the Gulf of Mexico and an upper level trough over the South Central U.S.  The high pressure system and the upper level trough will steer Francine toward the north-northeast during the next 24 hours.  On its anticipated track, the center of Tropical Storm Francine will move across Mississippi on Thursday.

Tropical Storm Francine will continue to weaken as it moves farther inland.  Even though Francine will weaken it will bring strong winds and heavy rain to southeastern Louisiana, Mississippi, South Alabama and Northwest Florida.  Heavy rain is likely to cause floods in some locations.

Flood Watches are in effect for parts of Louisiana, Mississippi, Alabama and Northwest Florida.

 

Hurricane Francine Strengthens to Cat. 2

Hurricane Francine strengthened to Category 2 on the Saffir-Simpson Scale on Wednesday afternoon as it neared southeast Louisiana.  At 5:00 p.m. EDT on Wednesday the center of Hurricane Francine was located at latitude 29.2°N and longitude 91.5°W which put the center about 40 miles (65 km) south-southwest of Morgan City, Louisiana.  Francine was moving toward the northeast at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 972 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Cameron to the Vermilion/Cameron Parish Line, Louisiana.  A Tropical Storm Warning is in effect for the portion of the coast from Grand Isle, Louisiana to the Alabama/Florida border.  The Tropical Storm Warning includes New Orleans, Lake Pontchartrain and Lake Maurepas.

Data from reconnaissance aircraft in Hurricane Francine on Wednesday afternoon indicated that Francine had strengthened to a Category 2 Hurricane.  A large circular eye with a diameter of 45 miles (75 km) was at the center of Francine’s circulation.  The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Thunderstorms were occurring in bands in the northern and eastern sides of Francine’s circulation.  Bands in the southern and western sides of Hurricane Francine consisted primarily of showers and lower clouds.

The center of Hurricane Francine appeared to wobble slightly to the east as it approached the coast of Louisiana.  The northern part of the eyewall  of Hurricane Francine was moving over the coast of southeast Louisiana south of Morgan City.  A NOAA National Ocean Service station north of Eugene Island, Louisiana (EINL1) reported a sustained wind speed of 75 m.p.h. (120 km/h) and a wind gust of 99 m.p.h. ((160 km/h).  The station reported a surface pressure of 981.4 mb.

The strongest winds were occurring southeast of the center of Hurricane Francine.  Winds to hurricane force extended out 40 miles (65 km) from the center of Francine’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Hurricane Francine.

The Hurricane Intensity Index (HII) was 16.5.  The Hurricane Size Index (HSI) was 13.7 and the Hurricane Wind Intensity Size Index (HWISI) was 30.2.  Hurricane Francine was similar in intensity to Hurricane Idalia when Idalia hit Florida in 2023.  Francine was larger than Idalia was.

Hurricane Francine will move between a high pressure system that extends from the western Atlantic Ocean to the Gulf of Mexico and an upper level trough over the South Central U.S,  The high pressure system and the upper level trough will steer Francine toward the northeast during the next 24 hours.  On its anticipated track, the center of Hurricane Francine will make landfall on the southeast coast of Louisiana late during the next several hours.  Francine will move across southeast Louisiana on Wednesday night.

Hurricane Francine will bring strong winds and heavy rain to Louisiana.  Heavy rain was already falling on many places in southeast Louisiana.  Francine will be capable of causing serious damage.  Widespread outages of electricity are likely.  Heavy rain is likely to cause floods.  The heaviest rain will fall as the center of Francine’s circulation approaches a given location.   Hurricane Francine will also drop heavy rain over parts of Mississippi, South Alabama and Northwest Florida as it moves inland.

Flood Watches are in effect for parts of Louisiana, Mississippi, Alabama and Northwest Florida.

Hurricane Francine could cause a storm surge of up to 10 feet (3 meters) along parts of the coast of Louisiana.  The highest surge will occur just to the east of where the center of Francine makes landfall in southeast Louisiana.  The storm surge will continue after the center of Hurricane Francine makes landfall because southerly winds will continue to push water toward the coast.

A Storm Surge Warning is in effect for the portion of the coast from Cameron/Vermilion Parish Line, Louisiana to the Mississippi/Alabama border.  The Storm Surge Warning includes Vermilion Bay, Lake Pontchartrain and Lake Maurepas.

 

Hurricane Francine Nears Louisiana

Hurricane Francine neared the coast of Louisiana on Wednesday morning.  At 11:00 a.m. EDT on Wednesday the center of Hurricane Francine was located at latitude 28.0°N and longitude 92.7°W which put the center about 150 miles (240 km) southwest of Morgan City, Louisiana.  Francine was moving toward the northeast at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 976 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Sabine Pass to the Vermilion/Cameron Line, Louisiana.  A Tropical Storm Warning is in effect for the portion of the coast from Grand Isle, Louisiana to the Alabama/Florida border.  The Tropical Storm Warning includes New Orleans, Lake Pontchartrain and Lake Maurepas.

Hurricane Francine maintained its intensity as it moved closer to the coast of Louisiana on Wednesday morning.  An upper level trough over the South Central U.S. was producing southwesterly winds that were blowing toward the top of Francine’s circulation.  Those winds were causing the vertical wind shear to increase.  In addition, the circulation around the western side of Hurricane Francine was pulling drier air into the southern part of Francine’s circulation.  Francine maintained its intensity even with the effects of the increased wind shear and drier air.

The effect of the vertical wind shear and the drier air also affected the structure of Hurricane Francine.  A large circular eye with a diameter of 45 miles (75 km) was at the center of Francine’s circulation.  The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  The break in the ring of thunderstorms was south of the eye of Hurricane Francine.  Storms near the center of Francine generated upper level divergence that pumped mass away to the northeast of the hurricane.  The removal of mass in the upper levels almost balanced the inflow of mass in the lower levels and the surface pressure remained nearly steady.

The wind shear and drier air also affect the distribution of thunderstorms in Hurricane Francine.  Thunderstorms were occurring in bands in the northern and eastern sides of Francine’s circulation.  Bands in the southern and western sides of Hurricane Francine consisted primarily of showers and lower clouds.

The size of the circulation around Hurricane Francine remained steady.  Winds to hurricane force extended out 40 miles (65 km) from the center of Francine’s circulation.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Hurricane Francine.

The Hurricane Intensity Index (HII) for Hurricane Francine was 13.9.  The Hurricane Size Index (HSI) was 13.5 and the Hurricane Wind Intensity Size Index (HWISI) was 27.4.  Hurricane Francine was similar in size and intensity to Hurricane Hanna when Hanna hit South Texas in 2020.

Hurricane Francine will move through an environment marginally favorable for intensification during the next 18 hours.  Francine will move over water where the Sea Surface Temperatures are near 30°C.  However, the upper level trough over the South Central U.S. will cause moderate vertical wind shear.  The drier air in the southern half of Francine’s circulation will also inhibit intensification.  Hurricane Francine is likely to maintain its current intensity during the next few hours until it reaches Louisiana.

Hurricane Francine will move between a high pressure system that extends from the western Atlantic Ocean to the Gulf of Mexico and the upper level trough over the South Central U.S,  The high pressure system and the upper level trough will steer Francine toward the northeast during the next 24 hours.  On its anticipated track, the center of Hurricane Francine will make landfall on the southeast coast of Louisiana late on Wednesday afternoon.

Hurricane Francine will bring strong winds and heavy rain to Louisiana. Francine will be capable of causing serious damage. Widespread outages of electricity are likely. Heavy rain is likely to cause flash floods.  The heaviest rain will fall as the center of Francine’s circulation approaches a given location.  Hurricane Francine will also drop heavy rain over parts of Mississippi, South Alabama and Northwest Florida as it moves inland.

Flood Watches are in effect for parts of Louisiana, Mississippi, South Alabama and Northwest Florida.

Hurricane Francine could cause a storm surge of up to 10 feet (3 meters) along parts of the coast of Louisiana.  The highest surge will occur just to the east of where the center of Francine makes landfall in southeast Louisiana.  The storm surge will continue after the center of Hurricane Francine makes landfall because southerly winds will continue to push water toward the coast.

A Storm Surge Warning is in effect for the portion of the coast from Cameron, Louisiana to the Mississippi/Alabama border.  The Storm Surge Warning includes Vermilion Bay, Lake Pontchartrain and Lake Maurepas.

 

Francine Strengthens to a Hurricane Southwest of Louisiana

Former Tropical Storm Francine strengthened to a hurricane southwest of Louisiana on Tuesday evening.  At 11:00 p.m. EDT on Tuesday the center of Hurricane Francine was located at latitude 26.4°N and longitude 94.3°W which put the center about 295 miles (475 km) southwest of Morgan City, Louisiana.  Francine was moving toward the northeast at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 979 mb.

Reconnaissance aircraft from the U.S. Air Force Reserve and NOAA found that former Tropical Storm Francine had intensified to a hurricane on Tuesday evening.  An eye with a diameter of 15 miles (24 km) was at the center of Hurricane Francine.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Francine’s circulation.  Storms near the core generated upper level divergence that pumped more mass away from the hurricane.  The removal of more mass caused the surface pressure to decrease more rapidly.

The strongest winds were occurring in the eastern side of Hurricane Francine.  Winds to hurricane force extended out 35 miles (55 km) in the eastern side of Francine’s circulation.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Hurricane Francine.

Hurricane Francine will move through an environment very favorable for intensification during the next 18 hours.  Francine will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the western Gulf of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Francine will intensify during the next 18 hours.  Francine could intensify rapidly at times now that there is an inner core.

Hurricane Francine will move between a high pressure system that extends from the western Atlantic Ocean to the Gulf of Mexico and an upper level trough over the South Central U.S,  The high pressure system and the upper level trough will steer Francine toward the northeast during the next 24 hours.  On its anticipated track, the center of Hurricane Francine will make landfall on the southeast coast of Louisiana late on Wednesday afternoon.

Hurricane Francine will bring strong winds and heavy rain to Louisiana.   Francine will be capable of causing serious damage.   Widespread outages of electricity are likely.  Heavy rain is likely to cause flash floods.  Hurricane Francine will also drop heavy rain over parts of Mississippi, South Alabama and Northwest Florida as it moves inland.

Rainbands in the western side of Tropical Storm Francine were dropping heavy rain on parts of south Texas.  A Flash Flood Warning is in effect for the area around Brownsville, Texas.

The circulation around Tropical Storm Francine showed signs of developing an inner core on Tuesday morning.  The inner end of a rainband wrapped most of the way around the center of Francines’s circulation.  An eye with a diameter of 25 miles (40 km) appeared to be forming at the center of Tropical Storm Francine.  The eye was surrounded by a nearly complete ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Thunderstorms were occurring in bands in the northeastern part of Francine’s circulation.  Thunderstorms were also occurring in bands in the western side of Tropical Storm Francine.

The size of the circulation around Tropical Storm Francine contracted a little as it began to resemble a typical tropical cyclone.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Francine’s circulation.

Tropical Storm Francine will move through an environment very favorable for intensification during the next 24 hours.  Francine will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the western Gulf of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Storm Francine will intensify to a hurricane during the next 24 hours.  Francine could intensify rapidly after the inner core is fully formed.

Tropical Storm Francine will move around the western part of a high pressure system that extends from the western Atlantic Ocean to the Gulf of Mexico.  The high pressure system will steer Francine toward the northeast during the next 24 hours.  On its anticipated track, Tropical Storm Francine will move toward Louisiana.  Francine will move faster toward the northeast on Wednesday when an upper level trough over the south central U.S. also begins to steer it toward the coast.  Tropical Storm Francine will approach the coast of Louisiana on Wednesday afternoon.  Francine will be a hurricane when it approaches the coast of Louisiana.

Tropical Storm Francine will bring strong winds and heavy rain to Louisiana.  Francine will be capable of causing serious damage.  Widespread outages of electricity are likely.  Heavy rain is likely to cause flash floods.

A U.S. Air Force Reserve Hurricane Hunter plane investigated a low pressure system over the western Gulf of Mexico previously designated as Potential Tropical Cyclone Six on Monday morning.  The crew of the aircraft found that the circulation around the low pressure system was more organized.  Based on the data from the aircraft, the U.S. National Hurricane Center determined that former Potential Tropical Cyclone Six had developed the characteristics of a tropical storm.  The National Hurricane Center designated former Potential Tropical Cyclone Six as Tropical Storm Francine.

A distinct low level center of circulation formed at the center of Tropical Storm Francine.  Thunderstorms had formed near the center of Francine’s circulation.  More thunderstorms also developed in bands revolving around the center of Tropical Storm Francine.  Storms near the center of Francine generated upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Francine was more symmetrical on Monday morning.  Winds to tropical storm force extended out 160 miles (260 km) from the center of Francine’s circulation.

Tropical Storm Francine will move through an environment very favorable for intensification during the next 24 hours.  Francine will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the western Gulf of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Storm Francine is likely to intensify gradually during the next few hours while an inner core develops.  Francine could intensify rapidly on Tuesday after an inner core forms.  Tropical Storm Francine is likely to strengthen to a hurricane on Tuesday.

Tropical Storm Francine will move around the western part of a high pressure system that extends from the western Atlantic Ocean to the Gulf of Mexico.  The high pressure system will steer Francine toward the north during the next 24 hours.  On its anticipated track, Tropical Storm Francine will move toward Louisiana.  Francine will move more toward the northeast on Wednesday when an upper level trough over the south central U.S. begins to steer it toward the coast.  Tropical Storm Francine will approach the coast of Louisiana on Wednesday afternoon.  Francine is likely to be a hurricane when it approaches the coast of Louisiana.

Ida will move northeast over Mississippi on Monday. Hurricane Ida will continue to drop locally heavy rain over eastern Louisiana and southern Mississippi, during the overnight hours. Heavy rain will spread over the rest of Mississippi, western Alabama and southwestern Tennessee on Monday. Flash Flood Watches have been issued for those locations. Ida will be over Tennessee on Tuesday and it will bring rain to the Tennessee River Valley and the Ohio River Valley.

Powerful Hurricane Ida Hits Southeast Louisiana

Powerful Hurricane Ida hit southeast Louisiana on Sunday. At 2:00 p.m. EDT on Sunday the center of Hurricane Ida was located at latitude 29.2°N and longitude 90.3°W which put it about 35 miles (55 km) southeast of Houma, Louisiana. Ida was moving toward the northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 180 m.p.h. (290 km/h). The minimum surface pressure was 930 mb.

A Hurricane Warning was in effect for the portion of the coast from Intracoastal City, Louisiana to the Mouth of the Pearl River. The Hurricane Warning included New Orleans, Lake Pontchartrain and Lake Maurepas. Tropical Storm Warnings were in effect for the portions of the coast from Cameron, Louisiana to Intracoastal City and from the Mouth of the Pearl River to the Alabama/Florida Line.

According to the National Hurricane Center the center of Hurricane Ida made landfall near Port Fourchon, Louisiana. That location was about 60 miles (95 km) south of New Orleans, about 15 miles southwest of Grand Isle, and about 45 miles southeast of Houma. Ida rapidly intensified to Category 4 on the Saffir-Simpson Scale as it approached the coast. The maximum sustained wind speed was 150 m.p.h. (240 km/h) at the time of landfall. The Hurricane Intensity Index (HII) for Hurricane Ida was 31.5. The Hurricane Size Index (HSI) was 15.3 and the Hurricane Wind Intensity Size Index (HWISI) was 46.8. Hurricane Ida was as intense as Hurricane Laura was in 2020. Ida was a little smaller than Laura was.

A weather station at Southwest Pass with an anemometer 125 feet (38 meters) above the station measured a sustained wind speed of 105 m.p.h. (169 km/h) and a wind gust of 121 m.p.h. (195 km/h). A weather station at Pilot’s Station with an anemometer 20 meters above the surface measured a sustained wind speed of 106 m.p.h. (170 km/h) and a wind gust of 128 m.p.h. (205 km/h). Southeasterly winds blowing around the eastern side of Hurricane Ida were pushing water toward the coast. Gauges at Shell Beach, Louisiana and the Waveland Mississippi Yacht Club both measured water level rises of approximately 7 feet (2 meters). Widespread power outages were reported around New Orleans.

Hurricane Ida will move slowly inland during the rest of Sunday. Ida will weaken gradually because it will be moving over a relatively flat surface that includes marshes and bayous. The center of Hurricane Ida will be near Houma, Louisiana in a few hours. Strong southeasterly winds will continue to push water toward the coast and the storm surge will continue until Hurricane Ida moves farther inland and weakens. A Storm Surge Warning is in effect for the portion of the coast from Intracoastal City, Louisiana to the Alabama/Florida border. The Storm Surge Warning includes Lake Pontchartrain, Lake Maurepas, Lake Borgne and Mobile Bay. Ida will pass near Baton Rouge on Sunday night. Hurricane Ida could produce hurricane force wind gusts near New Orleans and Baton Rouge. More widespread power outages could occur over southeast Louisiana. Ida will move northeast over Mississippi on Monday. It will drop locally heavy rain over eastern Louisiana, Mississippi, western Alabama and southwestern Tennessee. Flash Flood Watches have been issued for those locations.

Hurricane Ida Rapidly Intensifies to Cat. 4

Hurricane Ida rapidly intensified to Category 4 on the Saffir-Simpson Scale during the overnight hours. At 7:00 a.m. EDT on Sunday the center of Hurricane Ida was located at latitude 28.3°N and longitude 89.4°W which put it about 75 miles (120 km) south-southeast of Grand Isle, Louisiana. Ida was moving toward the northwest at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 175 m.p.h. (280 km/h). The minimum surface pressure was 935 mb.

A Hurricane Warning was in effect for the portion of the coast from Intracoastal City, Louisiana to the Mouth of the Pearl River. The Hurricane Warning included New Orleans, Lake Pontchartrain and Lake Maurepas. Tropical Storm Warnings were in effect for the portions of the coast from Cameron, Louisiana to Intracoastal City and from the Mouth of the Pearl River to the Alabama/Florida Line.

Hurricane Ida rapidly intensified to Category 4 southeast of Louisiana on Saturday night. A circular eye with a diameter of 17 miles (28 km) was at the center of Ida. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Ida. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the hurricane. The removal of mass caused the surface pressure to decrease rapidly and the wind speed increased quickly.

The circulation around Hurricane Ida increased in size when it rapidly intensified. Winds to hurricane force extended out 40 miles (65 km) from the center of Ida. Winds to tropical storm force extended out 140 miles (220 km) from the center of circulation. The Hurricane Intensity Index (HII) for Ida was 31.5. The Hurricane Size Index (HSI) was 14.1 and the Hurricane Wind Intensity Size Index (HWISI) was 45.6. Hurricane Ida was as strong as Hurricane Laura was last year and Ida was just a little smaller than Laura was. Hurricane Ida will be capable of causing regional severe damage.

Hurricane Ida will move through an environment favorable for intensification during the next few hours. Hurricane Ida will move over water where the Sea Surface Temperature is near 30˚C.  It will be under an upper level ridge over the Gulf of Mexico.  The winds will be weak in the ridge and there will be little vertical wind shear.  Ida could strengthen a little more before it makes landfall in southeast Louisiana. Hurricane Ida could pull some slightly drier air over the southeastern U.S. into its circulation when it nears the coast. If that happens, Ida will stop intensifying and it could weaken slightly just before it makes landfall.

Hurricane Ida will move around the southwestern part of a high pressure system that extends from the Atlantic Ocean to the eastern Gulf of Mexico.  The high will steer Ida toward the northwest during the next 12 hours.  On its anticipated track Hurricane Ida is likely to make landfall the coast of southeast Louisiana as a major hurricane in a few hours.  Ida will be capable of causing severe damage. Hurricane Ida could cause a storm surge of up to 12 to 16 feet (3.6 to 5 meters). A Storm Surge Warning has been issued for the coast from west of Vermillion Bay to the Mississippi/Alabama border. The Storm Surge Warning includes Vermillion Bay, Lake Borgne, Lake Pontchartrain, and Lake Maurepas. Hurricane Ida move toward the north as it moves inland over southeastern Louisiana. Ida could produce hurricane force winds in New Orleans and Baton Rouge. Widespread power outages could occur in southeast Louisiana. Ida will also drop heavy rain over parts of eastern Louisiana and Mississippi. Flash floods could occur in that region.

Hurricane Ida Strengthens to Cat. 2

Hurricane Ida strengthened to a Category 2 hurricane on the Saffir-Simpson Scale on Saturday. At 2:00 p.m. EDT on Saturday the center of Hurricane Ida was located at latitude 25.6°N and longitude 86.6°W which put it about 380 miles (610 km) southeast of Houma, Louisiana. Ida was moving toward the northwest at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h). The minimum surface pressure was 976 mb.

A Hurricane Warning was in effect for the portion of the coast from Intracoastal City, Louisiana to the Mouth of the Pearl River. The Hurricane Warning included New Orleans, Lake Pontchartrain and Lake Maurepas. Tropical Storm Warnings were in effect for the portions of the coast from Cameron, Louisiana to Intracoastal City and from the Mouth of the Pearl River to the Alabama/Florida Line.

Hurricane Ida strengthened Saturday over the Gulf of Mexico. A circular eye with a diameter of 28 miles (44 km) was visible on satellite images. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Ida. Storms near the core generated upper level divergence that pumped mass away from the hurricane. Winds to hurricane force extended out 30 miles (50 km) from the center of Ida. Winds to tropical storm force extended out 130 miles (210 km) from the center of circulation.

Hurricane Ida will move through an environment that will be very favorable for intensification during the next 24 hours.  Hurricane Ida will move over water where the Sea Surface Temperature is near 30˚C.  It will move under an upper level ridge over the Gulf of Mexico.  The winds will be weak in the ridge and there will be little vertical wind shear.  Hurricane Ida will strengthen and it is likely to undergo a period of rapid intensification that will cause it to strengthen to a major hurricane.  Ida could reach Category 4 on the Saffir-Simpson Scale. Hurricane Ida could pull some slightly drier air over the southeastern U.S. into its circulation when it nears the coast. If that happens, Ida will stop intensifying and it could weaken slightly just before it makes landfall.

Hurricane Ida will move around the southwestern part of a high pressure system that extends from the Atlantic Ocean to the eastern Gulf of Mexico.  The high will steer Ida toward the northwest during the next 24 hours.  On its anticipated track Hurricane Ida is likely to approach the coast of southeast Louisiana as a major hurricane by the middle of the day on Sunday.  Ida will be capable of causing major damage when it approaches the coast. I t could cause a storm surge of up to 10 to 15 feet (3 to 4.5 meters). A Storm Surge Warning has been issued for the coast from west of Vermillion Bay to the Mississippi/Alabama border. The Storm Surge Warning includes Vermilion Bay, Lake Borgne, Lake Pontchartrain, and Lake Maurepas. Hurricane Ida could move more slowly when it nears the coast on Sunday. That could prolong the duration of strong winds. Widespread power outages could occur in southeast Louisiana. Ida will also drop heavy rain over parts of eastern Louisiana and Mississippi. Flash floods could occur in that region. Mandatory and voluntary evacuations have been announced for parts of southeastern Louisiana.

Hurricane Ida probably will not be as strong or as large as Hurricane Laura was last year.  Ida could be a little bigger and a little stronger than Hurricane Delta was when it approached Louisiana in 2020. Ida is likely to be bigger and strong than Hurricane Zeta was when Zeta hit the same part of Louisiana in 2020.
