Tropical Storm Idalia Causes Hurricane Warning for West Coast of Florida

The imminent threat posed by Tropical Storm Idalia caused the issuance of a Hurricane Warning for the west coast of Florida on Monday morning. At 11:00 a.m. EDT on Monday the center of Tropical Storm Idalia was located at latitude 20.8°N and longitude 85.2°W which put it about 80 miles (130 km) south-southwest of the western end of Cuba. Idalia was moving toward the north at 8 m.p.h. (13 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.

A Hurricane Warning was in effect for the portion of the coast from the Ochlockonee River to the middle of Longboat Key, Florida. The Hurricane Warning included Tampa Bay. A Hurricane Warning was also in effect for the Cuban Province of Pinar del Rio. A Hurricane Watch was in effect for the portions of the coast from Englewood to the middle of Longboat Key, Florida and from the Ochlockonee River to Indian Pass, Florida. A Tropical Storm Warning was in effect for the portion of the coast from Chokoloskee to the middle of Longboat Key, Florida.

Tropical Storm Idalai strengthened gradually on Monday morning. Winds to tropical storm force extended out 100 miles (160 km) from the center of Idalia’s circulation. Even though Tropical Storm Idalia was stronger, the distribution of thunderstorms was asymmetrical. Most of the thunderstorms in Idalia were in bands in the southern and eastern parts of the circulation. Bands north and west of the center of circulation consisted primarily of showers and lower clouds. Tropical Storm Idalia was under the eastern part of an upper level ridge over the Yucatan Peninsula. The ridge was producing northeasterly winds that were blowing toward the top of Idalia’s circulation. Those winds were causing vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms.

Tropical Storm Idalia will move into an environment that will become more favorable for intensification during the next 24 hours. Idalia will be over water where the Sea Surface Temperatures are near 30°C. It will move into a region between the upper level ridge over the Yucatan Peninsula and an upper level low over the northern Gulf of Mexico. The upper level winds are weaker between the ridge and the low and there will be less vertical wind shear. Tropical Storm Idalia will intensify to a hurricane during the next 24 hours. Idalia could intensify rapidly when the upper level winds weaken. Idalia could strengthen to a major hurricane on Tuesday.

Tropical Storm Idalia will move around the western end of high pressure system over the western Atlantic Ocean. The high pressure system will steer Idalia toward the north during the next 24 hours. The center of Idalia will pass near the western end of Cuba in a few hours. On its anticipated track Tropical Storm Idalia will move over the eastern Gulf of Mexico on Monday night. An upper level trough over the eastern U.S. will turn Idalia toward the northeast later on Tuesday. Idalia is likely to make landfall on the west coast of Florida on Wednesday morning. Idalia could make landfall as a major hurricane.

Tropical Storm Idalia will drop heavy rain over parts of the northeastern Yucatan Peninsula and western Cuba. Heavy rain could cause flash floods in some locations.

Tropical Storm Idalia could be be a major hurricane when it reaches the west coast of Florida. Idalia is likely to make landfall in an area where high storm surges can occur. Idalia could cause a storm surge of up to 12 feet (3.5 meters) near where the center makes landfall. A Storm Surge Warning has been issued for the portion of the coast from Englewood to Ocholockonee River, Florida. The Storm Surge Warning includes Tampa Bay. Idalia will bring strong winds and heavy rain to parts of central and northern Florida. Widespread outages of electricity are likely. Heavy rain could cause flash floods in some locations.

Elsewhere, Hurricane Franklin rapidly intensified to Category 4 on the Saffir-Simpson Scale was over the Atlantic Ocean southwest of Bermuda. At 11:00 a.m. EDT on Monday the center of Hurricane Franklin was located at latitude 27.8°N and longitude 71.0°W which put it about 480 miles (770 km) southwest of Bermuda. Franklin was moving toward the north at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 145 m.p.h. (230 km/h) and there were wind gusts to 170 m.p.h. (280 km/h). The minimum surface pressure was 937 mb. A Tropical Storm Watch was in effect for Bermuda.

Tropical Storm Idalia Prompts Hurricane Watch for West Coast of Florida

A risk posed by Tropical Storm Idalia prompted the issuance of a Hurricane Watch for part of the west coast of Florida. At 5:00 p.m. EDT on Sunday the center of Tropical Storm Idalia was located at latitude 20.1°N and longitude 85.5°W which put it about 95 miles (155 km) east-southeast of Cozumel. Idalia was moving toward the northeast at 3 m.p.h. (5 km/h). The maximum sustained wind speed was 40 m.p.h. (60 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 995 mb.

A Tropical Storm Watch was also in effect for the Dry Tortugas. A Tropical Storm Watch was in effect for the Isle of Youth.

Tropical Storm Idalia did not change a lot on Sunday afternoon. A few more thunderstorms developed near the low level center of circulation. The low level center of circulation was meandering around inside of a larger counterclockwise rotation over the Northwestern Caribbean Sea. There were bands of showers and thunderstorms in the larger counterclockwise circulation. The thunderstorms in the larger circulation generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 70 miles (110 km) from the low level center of circulation.

Tropical Storm Idalia will be in an environment mostly favorable for intensification during the next 24 hours. Idalia will be over water where the Sea Surface Temperatures are near 30°C. It will be under an upper level ridge over the Yucatan Channel. The winds are weak in the upper level ridge and there will be little vertical wind shear. However, much of the air moving around the western side of Tropical Storm Idalia will pass over the northeastern Yucatan Peninsula. Some of the air in the eastern side of the Idalia will pass over western Cuba. The flow of air over land will inhibit intensification, but it probably will not prevent intensification. Tropical Storm Idalia could intensify slowly during the next 12 hours. Idalia could intensify more quickly on Monday when it moves over the eastern Gulf of Mexico. Tropical Storm Idalia is forecast to strengthen to a hurricane by Monday night

.Tropical Storm Idalia will be in a region where the steering currents are weak during the next 12 hours. Idalia may not move much during that time period.

A NOAA research aircraft found sustained tropical storm force winds in former Tropical Depression Ten on Sunday morning and the U.S. National Hurricane Center upgraded the system to Tropical Storm Idalia. There was a low level center of circulation meandering around inside of a larger counterclockwise rotation over the Northwestern Caribbean Sea. Thunderstorm activity fluctuated near the low level center of circulation. There were few thunderstorms currently near the low level center. There were bands of showers and thunderstorms in the larger counterclockwise circulation. The thunderstorms in the larger circulation generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 35 miles (50 km) from the low level center of circulation.

A low pressure system over the Yucatan Peninsula exhibited more organization on Saturday afternoon and the U.S. National Hurricane Center designated it as Tropical Depression Ten. The circulation around Tropical Depression Ten was still organizing. There was a weak center of circulation at the surface. Radar images from western Cuba indicated that there was a stronger circulation in the middle troposphere. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center started to generate upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Ten will be in an environment mostly 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 under an upper level ridge over the Yucatan Channel. The winds are weak in the upper level ridge and there will be little vertical wind shear. However, much of the air moving around the western side of Tropical Depression Ten will pass over the northeastern Yucatan Peninsula. Some of the air in the western side of the tropical depression will pass over western Cuba. The flow of air over land will inhibit intensification, but it probably will not prevent intensification. Tropical Depression Ten could intensify slowly on Sunday.

Tropical Depression Ten will be in a region where the steering currents are weak during the next 24 hours. Tropical Depression Ten may not move much on Sunday. A high pressure system over the western Atlantic Ocean will start to steer the tropical depression toward the north early next week. Tropical Depression Ten is likely to strengthen when it moves over the eastern Gulf of Mexico.

Tropical Depression Ten will drop heavy rain over parts of the northeastern Yucatan Peninsula and western Cuba. Heavy rain could cause flash floods in some locations.

Tropical Storm Watches Issued for South Florida and Western Cuba

The National Hurricane Center issued Tropical Storm Watches for South Florida and all of the Florida Keys on Thursday afternoon. The government of Cuba also issued Tropical Storm Watches for western Cuba. The National Hurricane Center designated former Invest 91L as Potential Tropical Cyclone One on Thursday afternoon. At 5:00 p.m. EDT on Thursday the center of Potential Tropical Cyclone One was located at latitude 21.4°N and longitude 87.5°W which put it about 75 miles (120 km) north-northwest of Cozumel, Mexico. Potential Tropical Cyclone One was moving toward the north at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1003 mb.

A Tropical Storm Watch was issued for the coast of Florida from Longboat Key on the west coast to the Volusia/Brevard County Line on the east coast. A Tropical Storm Watch was also issued for all of the Florida Keys. The government of Cuba issued Tropical Storm Watches for the provinces of Matanzas, Mayabeque, La Habana, Artemisa, Pinar del Rio and the Isle of Youth.

The National Hurricane Center designated former Invest 91L as Potential Tropical Cyclone One in keeping with its policy on the issuance of watches and warnings. The circulation around Potential Tropical Cyclone One consisted of a broad area of low pressure. One or more smaller centers of circulation were revolving around inside the broad area of low pressure. The National Hurricane Center identified a center near the northeast tip of the Yucatan Peninsula as the center of Potential Tropical Cyclone One. Images from satellites and radar indicated that a middle level center of circulation might be located near the western end of Cuba. The strongest thunderstorms were occurring in bands in the eastern side of Potential Tropical Cyclone One. Those thunderstorms were generating upper level divergence that pumped mass away to the east of the low pressure system. Bands in the western half of the circulation were over the Yucatan Peninsula and those bands consisted primarily of showers and lower clouds.

Potential Tropical Cyclone One will move through an environment that will be somewhat favorable for intensification during the next 36 hours. Potential Tropical Cyclone One will move over water where the Sea Surface Temperatures are near 28˚C. An upper level trough over the western Gulf of Mexico and an upper level ridge over the Northwest Caribbean Sea will interact to produce southwesterly winds that will blow toward the top of Potential Tropical Cyclone One. Those winds will cause moderate vertical wind shear. The vertical shear will somewhat inhibit intensification. However, the upper level ridge will also enhance the upper level divergence over Potential Tropical Cyclone One. More upper level divergence would cause the surface pressure to decrease. Potential Tropical Cyclone One is forecast to strengthen to a tropical storm during the next 36 hours.

The upper level trough over the western Gulf of Mexico and the upper level ridge over the Northwest Caribbean Sea will steer Potential Tropical Cyclone One toward the northeast during the next several days. On its anticipated track, Potential Tropical Cyclone One will approach Southwest Florida on Saturday morning. Potential Tropical Cyclone One will bring gusty winds and heavy rain to western Cuba and South Florida later this week. Heavy rain is likely to cause flash floods in some locations.

Hurricane Grace was intensifying on Wednesday morning. A reconnaissance plane found that an eye with a diameter of 18 miles (29 km) was forming at the center of Grace. The developing eye was surround 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 center of Hurricane Grace. Storms near the core of Grace were generating upper level divergence that was pumping mass away from the hurricane. The removal of mass was causing the surface pressure to decrease. Winds to hurricane force extended out 25 miles (40 km) on the eastern side of Grace. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation.

Hurricane Grace will move through an environment favorable for intensification during the next 12 hours. Grace will move over water where the Sea Surface Temperatures are near 30°C. It will move under the southern side of an upper level ridge centered near Florida. The ridge will produce easterly winds that will blow toward the top of Grace’s circulation. Those winds will cause some vertical wind shear, but the shear will be too small to prevent intensification. Hurricane Grace will continue to intensify during the next 12 hours. A period of rapid intensification could occur once an inner core with an eye and an eyewall is fully formed at the center of Grace.

Hurricane Grace will move south of a subtropical high pressure system over the Atlantic Ocean. The high will steer Grace toward the west-northwest during the next several days. On its anticipated track Hurricane Grace will approach the Yucatan Peninsula on Wednesday night. Grace will bring strong winds and locally heavy rain. Flash flooding is likely to occur in some locations. Grace will also cause a storm surge along the east coast of the Yucatan Peninsula.

The circulation around Zeta remained intact. Thunderstorms were occurring around the center of circulation. Bands of showers and thunderstorms were revolving around the core of Tropical Storm Zeta. Storms near the core generated upper level divergence which pumped mass away from the tropical storm. Wins to tropical storm force extended out 140 miles (220 km) from the center of Zeta.

Tropical Storm Zeta will move over the southern Gulf of Mexico during the next few hours. Zeta will move over water where the Sea Surface Temperature is near 29°C when it reaches the Gulf.  It will be under the western part of an upper level ridge where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Zeta is likely to intensify back into a hurricane on Tuesday. An upper level trough over the southwestern U.S. will produce southwesterly winds which will blow toward the top of Hurricane Zeta on Wednesday. Those winds will cause more vertical wind shear and Zeta could weaken when it moves over the northern Gulf of Mexico.

Tropical Storm Zeta will move around the western end of a ridge of high pressure. The ridge will steer Zeta toward the northwest on Tuesday. Zeta will move more toward the north on Wednesday when it moves around the western end of the ridge. The upper level trough is likely to steer Zeta toward the northeast as it approaches the Gulf Coast. Zeta could approach the coast of southeast Louisiana on Wednesday afternoon. Zeta is likely to still be a hurricane when it approaches the Gulf Coast

Zeta Intensifies to a Hurricane, Watches Issued for Gulf Coast

Former Tropical Storm Zeta intensified into a hurricane over the northwestern Caribbean Sea on Monday. At 5:00 p.m. EDT on Monday the center of Hurricane Zeta was located at latitude 19.5°N and longitude 86.0°W which put it about 90 miles (145 km) southeast of Cozumel, Mexico. Zeta was moving toward the northwest at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 981 mb.

A Hurricane Warning was in effect for the portion of the coast from Tulum to Dzilam, Mexico and the warning included Cancun and Cozumel. A Hurricane Watch was issued for the portion of the coast from Morgan City, Louisiana to the Mississippi/Alabama border. The Hurricane Watch included New Orleans, Lake Pontchartrain and Lake Maurepas. Tropical Storm Warnings were in effect for the portions of the coast from Punta Allen to Tulum, Mexico and from Dzilam to Progresso. Tropical Storm Watches were issued for the portions of the coast from Intracoastal City to Morgan City, Louisiana and from the Mississippi/Alabama border to Okaloosa/Walton County Line, Florida.

Former Tropical Storm Zeta intensified quickly into a hurricane on Monday. More thunderstorms formed near the center of circulation and the circulation became more symmetrical. Storms that formed near the center of Hurricane Zeta generated upper level divergence which pumped mass away from the hurricane. The removal of mass allowed the surface pressure to decrease, which contributed to the increase in wind speed. Winds to hurricane force extended out 25 miles (40 km) from the center in the northeast quadrant of Zeta. The winds in the other quadrants were blowing at less than hurricane force. Winds to tropical storm force extended out 120 miles (195 km) in the eastern half of Hurricane Zeta. Winds to tropical storm force extended out 80 miles (130 km) in the western half of Zeta.

Hurricane Zeta will move through an environment favorable for intensification during the next few hours and it could strengthen more. Zeta will move across the Yucatan Peninsula on Monday night. It will likely weaken while the center passes over land. Hurricane Zeta will move over the southern Gulf of Mexico on Tuesday. Zeta will move over water where the Sea Surface Temperature is near 29°C when it reaches the Gulf.  It will be under the western part of an upper level ridge where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Zeta is likely to intensify on Tuesday. An upper level trough over the southwestern U.S. will produce southwesterly winds which will blow toward the top of Hurricane Zeta. Those winds will cause more vertical wind shear and Zeta could weaken when it moves over the northern Gulf of Mexico.

Hurricane Zeta will move around the western end of a ridge of high pressure. The ridge will steer Zeta toward the northwest on Monday and Tuesday. On its anticipated track Hurricane Zeta will pass over the northeastern tip of Yucatan Peninsula on Monday night. Zeta will bring gusty winds and locally heavy rain to the northeastern Yucatan. It will also cause a storm surge of 4 to 7 feet (1 to 2 meters) along the coast where the wind blows the water toward the shore. Hurricane Zeta will move more toward the north on Wednesday when it moves around the western end of the ridge. Zeta could approach the coast of southeast Louisiana on Wednesday afternoon. Zeta is likely to still be a hurricane when it approaches the Gulf Coast
