Depression Prompts Tropical Storm Watch for Mexico

The formation of Tropical Depression Ten-E over the Eastern North Pacific Ocean prompted the issuance of a Tropical Storm Watch for a portion of the coast of Mexico.  At 5:00 p.m. EDT on Sunday the center of Tropical Depression Ten-E was located at latitude 13.8°N and longitude 98.7°W which put the center about 175 miles (280 km) south of Punta Maldonado, Mexico.  The tropical depression was stationary.  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1005 mb.

A Tropical Storm Watch was in effect for the portion of the coast from Punta Maldonado to Salina Cruz, Mexico.

A low pressure system over the Eastern North Pacific Ocean strengthened on Sunday afternoon and the U.S. National Hurricane Center designated the system as Tropical Depression Ten-E.  More thunderstorms formed near the center of Tropical Depression Ten-E.  Bands of showers and thunderstorms began to revolve around the center of the tropical depression.  Storms near the center of circulation began to generate upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Ten-E will move through an environment favorable for intensification during the next 24 hours.  The tropical depression will be over water where the Sea Surface Temperatures are near 30°C.  It will be in a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Depression Ten-E is likely to strengthen to a tropical storm during the next 24 hours.

Tropical Depression Ten-E will be in an area where the steering winds are weak during the next 24 hours.  The tropical depression is likely to move very slowly toward the north on Monday.  On its anticipated track, Tropical Depression Ten-E will move a little closer to Mexico.

Tropical Storm Ileana Makes Landfall on West Coast of Mexico

The center of Tropical Storm Ileana made landfall on the west coast of Mexico south of Los Mochis on Saturday afternoon.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Ileana was located at latitude 25.5°N and longitude 108.9°W which put the center about 20 miles (30 km) south-southeast of Los Mochis, Mexico.  Ileana was moving toward the north at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1002 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Altata to Huatabampito, Mexico.

The center of Tropical Storm Ileana made landfall on the west coast of Mexico near Topolobampo.  Thunderstorms were occurring in bands in the northern and eastern sides of the center of Ileana’s circulation.   Bands in the southern and western parts of Tropical Storm Ileana consisted primarily of showers and lower clouds.

The strongest winds were occurring in the eastern side of Tropical Storm Ileana.  Winds to tropical storm force extended out 60 miles (95 km) in the eastern side of Ileana’s circulation.  The winds in the western side of Tropical Storm Ileana were blowing at less than tropical storm force.

Tropical Storm Ileana will move around the western side of a high pressure system over Mexico.  The high pressure system will steer Ileana toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Ileana will move near the west coast of Mexico.

Tropical Storm Ileana will weaken to a tropical depression this evening as it moves a little farther inland.  Ileana will bring gusty winds and locally heavy rain to parts of Sinaloa.  Heavy rain could cause flash floods in some locations.

Tropical Storm Ileana Brings Wind and Rain to Southern Baja California

Tropical Storm Ileana brought gusty winds and rain to the southern part of Baja California on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Ileana was located at latitude 22.7°N and longitude 109.4°W which put the center about 35 miles (55 km) east-southeast of Cabo San Lucas, Mexico.   Ileana was moving toward the north-northwest at 7 m.p.h. (11 km/h).   The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (9 km/h).   The minimum surface pressure was 1000 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Santa Fe to San Evaristo, Mexico.  The Tropical Storm Warning includes Cabo San Lucas and La Paz.

A Tropical Storm Watch is in effect for the portion of the coast from San Evaristo to Loreto, Mexico.  A Tropical Storm Watch is in effect for the portion of the coast from Topolobampo to Huatabampito, Mexico.

The circulation around Tropical Storm Ileana was not particularly well organized on Friday afternoon.  The northwestern part of Illeana’s circulation was passing over the southern end of Baja California.  The flow of air over land may have been disrupting the circulation.  Thunderstorms were occurring in bands revolving around the center of Tropical Storm Ileana.  Easterly winds pushing air up slopes in southern Baja California may have been contributing to the development of thunderstorms in that part of Ileana’s circulation.  Storms near the center of Ileana generated upper level divergence that pumped mass away to the northeast of the tropical storm.

The distribution of wind speeds in Tropical Storm Ileana was asymmetrical.  Winds to tropical storm force extended out 60 miles (95 km) in the eastern side of Ileana’s circulation.  The winds in the western part of Tropical Storm Ileana were blowing at less than tropical storm force.

Tropical Storm Ileana will move through an environment that will become less favorable for intensification during the next 24 hours.  Ileana will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern part of an upper level trough over the Southwest U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Ileana’s circulation.  Those winds will cause the vertical wind shear to increase.  Tropical Storm Ileana is likely to weaken when the vertical wind shear increases.  The center of Ileana’s circulation could move across the southeastern tip of Baja California, which would also cause Tropical Storm Ileana to weaken.

Tropical Storm Ileana will move around the western end of a high pressure system over Mexico.  The high pressure system will steer Ileana toward the north during the next 24 hours.  On its anticipated track, the center of Tropical Storm Ileana will move across the southeastern tip of Baja California and over the southern Gulf of California.

Tropical Storm Ileana will continue to bring gusty winds and locally heavy rain to the southern part of Baja California during the next 24 hours.  Heavy rain could cause flash floods in some locations.

 

Tropical Storm Ileana Forms South of Baja California

Tropical Storm Ileana formed south of Baja California on Thursday afternoon.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Ileana was located at latitude 19.9°N and longitude 108.0°W which put the center about 240 miles (385 km) south-southeast of Cabo San Lucas, Mexico.  Ileana was moving toward the north-northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1001 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Santa Fe to San Evaristo, Mexico.  The Tropical Storm Warning includes Cabo San Lucas and La Paz.

A Tropical Storm Watch is in effect for the portion of the coast from San Evaristo to Loreto, Mexico.  A Tropical Storm Watch is in effect for the portion of the coast from Topolobampo to Huatabampito, Mexico.

A low pressure system over the Eastern North Pacific Ocean south of Baja California strengthened on Thursday afternoon and the U.S. National Hurricane Center designated the system as Tropical Storm Ileana.  More thunderstorms were developing near the center of Ileana’s circulation.  However, the distribution of theunderstorms in Tropical Storm Ileana was asymmetrical.  Thunderstorms were occurring in bands in the western side of Ileana’s circulation.  Bands in the eastern side of Ileana consisted primarily of showers and lower clouds.

The distribution of wind speeds in Tropical Storm Ileana was also asymmetrical.  Winds to tropical storm force extended out 80 miles (130 km) in the northeastern quadrant of Ileana’s circulation.  The winds in the other parts of Ileana were blowing at less than tropical storm force.

Tropical Storm Ileana will move through an environment somewhat favorable for intensification during the next 24 hours.  Ileana will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southwestern part of an upper level ridge over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Ileana’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  Tropical Storm Ileana is likely to intensify during the next 24 hours.

Tropical Storm Ileana will move around the western end of a high pressure system over Mexico.  The high pressure system will steer Ileana toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Ileana will reach the southern end of Baja California on Friday morning.

Tropical Storm Ileana will bring gusty winds and locally heavy rain to the southern part of Baja California.  Heavy rain could cause flash floods in some locations.

Tropical Storm Francine Churns over Western Gulf of Mexico

Tropical Storm Francine was churning over the western Gulf of Mexico on Tuesday morning.  At 8:00 a.m. EDT on Tuesday the center of Tropical Storm Francine located at latitude 24.5°N and longitude 94.9°W which put the center about 395 miles (640 km) south-southwest of Cameron, Louisiana.  Francine was moving toward the north at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 990 mb.

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.

Flood Watches are in effect for parts of Louisiana.

Tropical Storm Francine could cause a storm surge of up to 10 feet (3 meters) along parts of the coast of Louisiana.

A Storm Surge Warning is in effect for the portion of the coast from High Island, Texas to the Mouth of the Mississippi River.  The Storm Surge Warning includes Vermilion Bay.

 

 

Tropical Storm Francine Prompts Hurricane Watch for Louisiana

The risk posed by Tropical Storm Francine prompted the issuance of a Hurricane Watch for a portion of the coast of Louisiana on Monday morning.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Francine located at latitude 23.0°N and longitude 94.9°W which put the center about 480 miles (770 km) south-southwest of Cameron, Louisiana.  Francine was moving toward the north-northwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 1002 mb.

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.

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

Low Pressure System over Gulf of Mexico Designated Potential Tropical Cyclone Six

A low pressure system over the southwestern Gulf of Mexico was designated as Potential Tropical Cyclone Six by the U.S. National Hurricane Center on Sunday afternoon.  A Tropical Storm Watch was issued for the coast of northern Mexico.  At 5:00 p.m. EDT on Sunday the center of Potential Tropical Cyclone Six located at latitude 21.6°N and longitude 94.6°W which put the center about 340 miles (545 km) south-southeast of the Mouth of the Rio Grande River.  The low pressure system was moving toward the northwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 1003 mb.

A Tropical Storm Watch was in effect for the portion of the coast from Barra del Tordo,, Mexico to the Mouth of the Rio Grande River.

A U.S. Air Force Reserve Hurricane Hunter reconnaissance aircraft investigated a low pressure system over the southwest Gulf of Mexico that was previously designated as Invest 91L on Sunday afternoon.  The Hurricane Hunters found that there was a large low pressure system with a broad counterclockwise rotation.  The reconnaissance flight was unable to find a distinct low level center of circulation.  The flight crew did find a large area of tropical storm force winds in the western side of the low pressure system.

Winds to tropical storm force extended out 185 miles (295 km) in the western side of Potential Tropical Cyclone Six.  The winds in the eastern side of the low pressure system were blowing at less than tropical storm force.

The strongest winds in Potential Tropical Cyclone Six were occurring in bands of thunderstorms in the southwestern part of the low pressure system.  The bands in the other parts of the circulation consisted primarily of showers and lower clouds.  The storms in the southwestern part of Potential Tropical Cyclone Six began to generate upper level divergence that pumped mass away from the low pressure system.

Potential Tropical Cyclone Six will move through an environment mostly favorable for the intensification during the next 24 hours.  The low pressure system will move over water where the Sea Surface Temperatures are near 30°C.  It will move over the eastern part of an upper level ridge over northern Mexico and the western Gulf of Mexico.  The upper level ridge will produce northwesterly winds that will blow toward the top of Potential Tropical Cyclone Six’s circulation.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  The large size of the circulation around the low pressure system will also reduce the rate of intensification.  Potential Tropical Cyclone Six is likely to intensify slowly during the next 24 hours.  The low pressure system could intensify more rapidly after an inner core forms.

Potential Tropical Cyclone Six will move around the southwestern part of a high pressure system that extends from the western Atlantic Ocean to the Gulf of Mexico.  The high pressure system will steer the low pressure system toward the northwest during the next 24 hours.  On its anticipated track, Potential Tropical Cyclone Six will move toward northern Mexico.  The low pressure system will move more toward the north on Tuesday when it moves around the western end of the high pressure system.  It is likely to be southeast of Texas on Tuesday night.  Potential Tropical Cyclone Six could approach the coast of Louisiana on Wednesday.  It could be a hurricane when it approaches the coast of Louisiana.

Low Pressure System Forms over Bay of Campeche

A low pressure system formed over the Bay of Campeche on Saturday.  The low pressure system was designated as Invest 91L.  At 8:00 a.m. EDT on Saturday the center of the low pressure system was located at latitude 18.8°N and longitude 92.7°W which put the center about 150 miles (240 km) west of Campeche, Mexico.  The low pressure system was moving toward the west at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 25 m.p.h. (40 km/h) and there were wind gusts to 35 m.p.h. (55 km/h).  The minimum surface pressure was 1005 mb.

A low pressure system formed in the northern end of a tropical wave over the eastern Bay of Campeche on Saturday.  There was a well developed low level center of circulation that was visible on satellite images.  However, there were few thunderstorms near the center of circulation.  Thunderstorms were starting to form in bands in the eastern side of the low pressure system.  Bands in the rest of the low pressure system consisted primarily of showers and lower clouds.

The low pressure system designated as Invest 91L will move into an environment mostly favorable for the formation of a tropical cyclone during the next 36 hours.  The low pressure system will move over water where the Sea Surface Temperatures are near 31°C.  It will move over the eastern part of an upper level ridge over northern Mexico and the western Gulf of Mexico.  The upper level ridge will produce northerly winds that will blow toward the top of Invest 91L’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit the formation of a tropical cyclone, but the shear will not be enough to prevent the formation of a tropical depression or a tropical storm.

There is a second low pressure system embedded in a nearly stationary front over the northwestern Gulf of Mexico.  The second low pressure system could drift toward the southwest during the next day or two.  It is possible that the circulation around the second low pressure system and the circulation around Invest 91L could merge early next week.

The low pressure system designated as Invest 91L will move around the southwestern part of a high pressure system that extended from the western Atlantic Ocean to the Gulf of Mexico.  The high pressure system will steer Invest 91L toward the west-northwest during the next 24 hours.  On its anticipated track, the low pressure system designated as Invest 91L will move toward the western Bay of Campeche.

If the second low pressure system over the northwestern Gulf of Mexico interacts with Invest 91L, then the low pressure system designated as Invest 91L could get pulled toward the north during the first half of next week.  If Invest 91L get pulled toward the north, then it would spend more time over water and it would have more time to strengthen.  The low pressure system designated as Invest 91L could affect the coast of Texas and Louisiana in a few days.

Gilma Strengthens to a Major Hurricane

Hurricane Gilma strengthened to a major hurricane over the Eastern North Pacific Ocean between Baja California and Hawaii on Thursday morning.   At 5:00 a.m. EDT on Thursday the center of Hurricane Gilma was located at latitude 16.6°N and longitude 124.2°W which put the center about 1025 miles (1650 km) west-southwest of the southern tip of Baja California.  Gilma was moving toward the west-northwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 140 m.p.h. (220 km/h).  The minimum surface pressure was 963 mb.

Hurricane Gilma strengthened to a major hurricane over the Eastern North Pacific Ocean between Baja California and Hawaii on Thursday morning.  A circular eye with a diameter of 17 miles (28 km) was present at the center of Gilma’s circulation.  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 Hurricane Gilma.  Storms near the core of Gilma generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The circulation around Hurricane Gilma was symmetrical.  Winds to hurricane force extended out 30 miles (50 km) from the center of Gilma’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Hurricane Gilma.

Hurricane Gilma will move through an environment favorable for intensification during the next 24 hours.  Gilma will move over water where the Sea Surface Temperatures are near 28°C. It will move under the southern part of an upper level ridge over the Eastern north Pacific Ocean.  The upper level ridge will produce northeasterly winds that will blow toward the top of Gilma’s circulation.  Those winds will cause some vertical wind shear. The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  Hurricane Gilma is likely to continue to intensify during the next 24 hours.

Hurricane Gilma will move around the southern side of a subtropical high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Gilma slowly toward the west-northwest during the next 24 hours.  On its anticipated track, Hurricane Gilma will move farther away from Baja California.

 

Gilma Intensifies to a Hurricane

Former Tropical Storm Gilma intensified to a hurricane over the Eastern North Pacific Ocean between Baja California and Mexico on Wednesday morning.  At 11:00 a.m. EDT on Wednesday the center of Hurricane Gilma was located at latitude 16.0°N and longitude 122.8°W which put the center about 965 miles (1555 km) west-southwest of the southern tip of Baja California.  Gilma was moving toward the west at 7 m.p.h. (11 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 983 mb.

Former Tropical Storm Gilma intensified to a hurricane between Baja California and Hawaii on Wednesday morning.  The inner end of a rainband wrapped around the center of Hurricane Gilma.  A circular eye was evident on microwave satellite images of Gilma.  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 Hurricane Gilma.  Storms near the center of Gilma’s circulation generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The circulation around Hurricane Gilma was more symmetrical on Wednesday morning.  Winds to hurricane force extended out 30 miles (50 km) from the center of Gilma’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Hurricane Gilma.

Hurricane Gilma will move through an environment favorable for intensification during the next 24 hours.  Gilma will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southern part of an upper level ridge over the Eastern north Pacific Ocean.  The upper level ridge will produce northeasterly winds that will blow toward the top of Gilma’s circulation.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  Hurricane Gilma will continue to intensify during the next 24 hours.  Gilma could strengthen to a major hurricane later this week.

Hurricane Gilma will move around the southern side of a subtropical high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Gilma toward the west during the next 24 hours.  On its anticipated track, Hurricane Gilma will move farther away from Baja California.
