Hurricane Iota Drops Heavy Rain over Nicaragua and Honduras

Hurricane Iota was dropping heavy rain over Nicaragua and Honduras on Tuesday morning. At 10:00 a.m. EST on Tuesday the center of Hurricane Iota was located at latitude 13.7°N and longitude 85.2°W which put it about 135 miles (220 km) east of Tegucigapla, Honduras. Iota was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 980 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Bluefields, Nicaragua to the Honduras/Guatemala border including the Bay Islands.

Hurricane Iota continued to move steadily inland over Nicaragua on Tuesday morning. The center of Iota was just to the east of the border between Nicaragua and Honduras. Hurricane Iota was dropping heavy rain over much of Nicaragua and Honduras. Bands of showers and thunderstorms continued to revolve around the center of Iota. Those rainbands were dropping rain fast enough to cause flash floods over many of the same places that were flooded by Hurricane Eta.

Hurricane Iota will continue to move westward during the next 24 to 36 hours. Iota will weaken to a tropical storm when its center moves over Honduras during the next few hours. Iota will likely be a tropical depression when the center reaches El Salvador on Tuesday night. Even though Hurricane Iota will weaken steadily, it will continue to drop heavy rain over Nicaragua, Honduras and El Salvador. Catastrophic flash floods could occur in that region.

Dangerous Hurricane Iota Hits Nicaragua

Dangerous Hurricane Iota hit Nicaragua with powerful winds and heavy rain on Monday night. At 10:00 p.m. EST on Monday the center of Hurricane Iota was located at latitude 13.6°N and longitude 83.4°W which put it about 30 miles (50 km) south of Puerto Cabezas, Nicaragua. Iota was moving toward the west at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 185 m.p.h. (300 km/h). The minimum surface pressure was 920 mb.

A Hurricane Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Patuca, Honduras. Tropical Storm Warnings were in effect for the portions of the coast from Bluefields to Sandy Bay Sirpi, Nicaragua and from Punta Patuca to the Honduras/Guatemala border including the Bay Islands. Tropical Storm Warnings were also in effect for San Andres and Providencia Island.

Hurricane Iota was a powerful hurricane when it made landfall on the coast of Nicaragua just to the south of Puerto Cabezas. Iota was at Category 4 on the Saffir-Simpson Scale. Winds to hurricane force extended out 45 miles (75 km) from the center of circulation. Winds to tropical storm force extended out 175 miles (280 km) from the center, The Hurricane Intensity Index (HII) for Hurricane Iota was 33.3. The Hurricane Size Index (HSI) was 16.3 and the Hurricane Wind Intensity Size Index (HWISI) was 49.6. Iota was capable of causing regional significant damage.

Hurricane Iota made landfall on the same portion of the coast of Nicaragua devastated by Hurricane Eta two weeks ago. Iota will compound the damage caused by Eta. Strong winds will cause additional damage and they will destroy temporary shelters erected after Hurricane Eta. The winds blowing water toward the coast could cause a storm surge of up to 20 feet (6 meters) south of Puerto Cabezas.

Hurricane Iota will continue to move toward the west during the next 48 hours. On its anticipated track the center of Iota will move across northern Nicaragua, southern Honduras and El Salvador. The winds around Hurricane Iota will weaken steadily as it moves inland. Iota will drop heavy rain over Nicaragua, Honduras, and El Salvador. The heavy rain will cause flash floods and some floods will occur in the same locations flooded by Hurricane Eta.

Hurricane Iota Rapidly Intensifies to Cat. 5

Hurricane Iota rapidly intensified to Category 5 on the Saffir-Simpson Scale on Monday morning. At 10:00 a.m. EST on Monday the center of Hurricane Iota was located at latitude 13.5°N and longitude 82.0°W which put it about 100 miles (160 km) east-southeast of Cabo Gracias a Dios. Iota was moving toward the west at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 190 m.p.h. (305 km/h). The minimum surface pressure was 917 mb.

A Hurricane Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Patuca, Honduras and for Providencia Island. A Hurricane Watch was in effect for San Andres. Tropical Storm Warnings were in effect for the portions of the coast from Bluefields to Sandy Bay Sirpi, Nicaragua and from Punta Patuca to the Honduras/Guatemala border including the Bay Islands. A Tropical Storm Warning was also in effect for San Andres.

Hurricane Iota intensified very rapidly on Sunday night and it reached Category 5 on the Saffir-Simpson Scale on Monday morning. A reconnaissance aircraft found a circular eye with a diameter of 14 miles (22 km) at the center of Iota. 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 Iota. Storms near the core generated strong upper level divergence which pumped mass away from the hurricane in all directions. The removal of large quantities of mass allowed the surface pressure to decrease rapidly which produced the very rapid intensification.

Winds to hurricane force extended out 35 miles (55 km) from the center of Hurricane Iota. Winds to tropical storm force extended out 150 miles (240 km) from the center. The Hurricane Intensity Index (HII) for Hurricane Iota was 35.0. The Hurricane Size Index (HSI) was 13.9 and the Hurricane Wind Intensity Size Index (HWISI) was 48.9. Hurricane Iota was capable of causing catastrophic damage.

Hurricane Iota will move through an capable of supporting a very intense hurricane on Monday. Iota will move over water where the Sea Surface Temperature is near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. If the inner end of a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could begin. An eyewall replacement cycle could cause Hurricane Iota to start to weaken, but Iota could still be at Category 5 when it makes landfall on the northern coast of Nicaragua.

Hurricane Iota will move south of a high pressure system over the western Atlantic Ocean. The high will steer Iota toward the west during the next several days. On its anticipated track Iota could approach the coast a little to the south of the border between Nicaragua and Honduras on Monday night. Hurricane Iota will be a major hurricane when it reaches the coast and it could be at Category 5. Nicaragua and Honduras are still trying to cope with floods and other damage caused by Hurricane Eta. Another major hurricane could have catastrophic consequences for that region.

Hurricane Iota Rapidly Intensifies East of Nicaragua

Hurricane Iota rapidly intensified east of Nicaragua on Sunday morning. At 10:00 a.m. EST on Sunday the center of Hurricane Iota was located at latitude 13.2°N and longitude 77.8°W which put it about 380 miles (615 km) east-southeast of Cabo Gracias a Dios. Iota was moving toward the west-northwest at 6 m.p.h. (10 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 982 mb.

A Hurricane Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Patuca, Honduras and for Providencia Island. A Hurricane Watch was in effect for San Andres. Tropical Storm Warnings were in effect for the portions of the coast from Bluefields to Sandy Bay Sirpi, Nicaragua and from Punta Patuca to Punta Castilla, Honduras. A Tropical Storm Warning was also in effect for San Andres.

Hurricane Iota was intensifying rapidly on Sunday morning. A small eye formed at the center of Iota. 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 Iota. Storms near the core generated strong upper level divergence which pumped mass away from the hurricane. The removal of mass caused the surface pressure to decrease quickly, which contributed to the rapid intensification. Winds to hurricane force extended out 30 miles from the center of circulation. Winds to tropical storm force extended out 90 miles from the center.

Hurricane Iota will move through an environment very favorable for intensification during the next 36 hours. Iota will move over water where the Sea Surface Temperature is near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Iota is likely to continue to intensify rapidly. Iota could strengthen into a major hurricane within 24 hours and it could intensify to Category 4 on the Saffir-Simpson Scale.

Hurricane Iota will move south of a high pressure system over the western Atlantic Ocean. The high will steer Iota toward the west during the next several days. On its anticipated track Iota could approach the coast near the border between Nicaragua and Honduras on Monday night. Hurricane Iota is likely be a major hurricane when it reaches the coast. Nicaragua and Honduras are still trying to cope with floods and other damage caused by Hurricane Eta a few days ago. Another major hurricane could have catastrophic consequences for that region.

Elsewhere over the Atlantic Ocean, former Tropical Storm Theta weakened to a tropical depression southwest of Madeira. At 7:00 a.m. EST on Sunday the center of Tropical Depression Theta was located at latitude 31.8°N and longitude 18.3°W which put it about 120 miles (195 km) southwest of Madeira. Theta was moving toward the east at 3 m.p.h. (5 km/h). 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 1003 mb.

Tropical Storm Iota Strengthens, Hurricane Watches for Nicaragua and Honduras

Tropical Storm Iota strengthened on Saturday and Hurricane Watches were issued for the coasts of Nicaragua and Honduras. At 1:00 p.m. EST on Saturday the center of Tropical Storm Iota was located at latitude 12.6°N and longitude 76.4°W which put it about 485 miles (780 km) east-southeast of Cabo Gracias a Dios. Iota was moving toward the west-southwest 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 65 m.p.h. (105 km/h). The minimum surface pressure was 1002 mb.

A Hurricane Watch was issued for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Patuca, Honduras and for Providencia Island. Tropical Storm Warnings were in effect for San Andres and Providencia Island. A Tropical Storm Watch was issued for the portion of the coast from Punta Patuca to Punta Castilla, Honduras.

A U.S. Air Force Reserve Hurricane Hunter plane found on Saturday afternoon that Tropical Storm Iota had strengthened. The maximum sustained wind speed had increased to 50 m.p.h. (80 km/h) and the minimum surface pressure had decreased to 1002 mb. The circulation around Tropical Storm Iota was still organizing. Many of the stronger thunderstorms were occurring in bands on the eastern side of Iota. Bands in the western side of the circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 90 miles (145 km) in the eastern half of Iota. Most of the winds on the western side of the circulation were blowing at less than tropical storm force.

Tropical Storm Iota will move through an environment favorable for intensification during the next 48 hours. Iota will move over water where the Sea Surface Temperature is near 29°C. An upper level trough over the western Caribbean Sea has been producing southwesterly winds which were blowing toward the top of Iota. The upper level trough will move westward away from Tropical Storm Iota and the wind shear will decrease on Sunday. Iota is likely to strengthen more rapidly after an inner core is formed. Tropical Storm Iota could rapidly intensify into a hurricane on Sunday and it could strengthen to a major hurricane on Monday.

Tropical Storm Iota will move south of a high pressure system over the western Atlantic Ocean. The high will steer Iota toward the west during the next several days. On its anticipated track Iota could approach the coast of Nicaragua on Monday. It will likely be a hurricane at that time and it could be a major hurricane. Nicaragua and Honduras are still trying to cope with floods and other damage caused by Hurricane Eta a few days ago. Another hurricane could have catastrophic consequences for that region.

Elsewhere over the Atlantic Ocean, Tropical Storm Theta moved toward Madeira. At 10:00 a.m. EST on Saturday the center of Tropical Storm Theta was located at latitude 31.6°N and longitude 20.2°W which put it about 210 miles (340 km) west-southwest of Madeira. Theta was moving toward the east at 8 m.p.h. (13 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 1000 mb.

TD 31 Strengthens to Tropical Storm Iota

Former Tropical Depression Thirtyone strengthened to Tropical Storm Iota on Friday afternoon. At 4:00 p.m. EST on Friday the center of Tropical Storm Iota was located at latitude 13.8°N and longitude 73.8°W which put it about 335 miles (540 km) south-southeast of Kingston, Jamaica. Iota was moving toward the west-southwest at 3 m.p.h. (5 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 1006 mb.

The low level circulation around former Tropical Depression Thirtyone appeared to reform a little farther to the southeast near a band of showers and thunderstorms on Friday afternoon. Based on data from satellites the National Hurricane Center upgraded the depression to Tropical Storm Iota. The circulation around Iota was still organizing. A band of thunderstorms wrapped about three quarters of the way around the center of circulation on the southern, eastern and northern sides of the center. Other bands of showers and thunderstorms were revolving around the center of the Tropical Storm Iota. Storms near the center generated upper level divergence which pumped mass away to the north and east of the tropical storm. Winds to tropical storm force extended out 100 miles (160 km) on the eastern side of Iota. The winds on the western side of Iota were blowing at less than tropical storm force.

Tropical Storm Iota will move through an environment favorable for intensification during the weekend. Iota will move over water where the Sea Surface Temperature is near 29°C. An upper level trough over the western Caribbean Sea will produce southwesterly winds which blow toward the top of Iota during the next 12 hours. Those winds will cause vertical wind shear, but the shear will not be strong enough to prevent Tropical Storm Iota from becoming more organized. The upper level trough will move westward away from the depression and the wind shear will decrease during the weekend. Tropical Storm Iota is likely to strengthen more rapidly after an inner core is formed. Iota could rapidly intensify into a hurricane on Saturday and it could strengthen to a major hurricane by Sunday.

Tropical Storm Iota will move south of a high pressure system over the western Atlantic Ocean. The high will steer Iota toward the west during the next several days. On its anticipated track Iota could approach the coast of Nicaragua on Sunday. It will likely be a hurricane at that time and it could be a major hurricane. Nicaragua and Honduras are still trying to cope with floods and other damage caused by Hurricane Eta a few days ago. Another hurricane could have catastrophic consequences for that region.

Elsewhere over the Atlantic Ocean, Tropical Storm Theta Passed south of the Azores. At 4:00 p.m. EST on Friday the center of Tropical Storm Theta was located at latitude 31.9°N and longitude 22.6°W which put it about 490 miles (785 km) south-southeast of the Azores. Theta was moving toward the east at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 993 mb.

Tropical Depression 31 Forms over Caribbean Sea

Tropical Depression Thirtyone formed over the Caribbean Sea on Friday morning. At 10:00 a.m. EST on Friday the center of Tropical Depression Thirtyone was located at latitude 14.2°N and longitude 74.3°W which put it about 310 miles (500 km) south-southeast of Kingtson, Jamaica. The depression was moving toward the west-southwest at 7 m.p.h. (11 km/h). 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 1007 mb.

The circulation around an area of low pressure over the Caribbean Sea exhibited much better organization on visible satellite imagery on Friday morning and the National Hurricane Center designated the system as Tropical Depression Thirtyone. A band of thunderstorms wrapped about three quarters of the way around the center of circulation on the southern, eastern and northern sides of the center. Other bands of showers and thunderstorms were revolving around the center of the depression. Storms near the center generated upper level divergence which pumped mass away to the north and east of the depression.

Tropical Depression Thirtyone will move through an environment favorable for intensification during the weekend. The depression will move over water where the Sea Surface Temperature is near 29°C. An upper level trough over the western Caribbean Sea will produce southwesterly winds which blow toward the top of the depression during the next 12 hours. Those winds will cause vertical wind shear, but the shear may not be strong enough to prevent Tropical Depression Thirtyone from strengthening into a tropical storm. The upper level trough will move westward away from the depression and the wind shear will decrease during the weekend. Tropical Depression Thirtyone is likely to strengthen into a tropical storm during the next 12 hours. It could rapidly intensify into a hurricane on Saturday and it could strengthen to a major hurricane by Sunday.

Tropical Depression Thirtyone will move south of a high pressure system over the western Atlantic Ocean. The high will steer the depression toward the west during the next several days. On its anticipated track it could approach the coast of Nicaragua on Sunday. It will likely be a hurricane at that time and it could be a major hurricane. Nicaragua and Honduras are still trying to cope with floods and other damage caused by Hurricane Eta a few days ago. Another hurricane could have catastrophic consequences for that region.

Elsewhere over the Atlantic Ocean, Tropical Storm Theta Passed south of the Azores and Tropical Storm Eta completed a transition to an extratropical cyclone. At 10:00 a.m. EST on Friday the center of Tropical Storm Theta was located at latitude 31.7°N and longitude 23.8°W which put it about 470 miles (760 km) south-southeast of the Azores. Theta was moving toward the east at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 993 mb.

Tropical Storm Eta Brings Wind and Rain to Tampa

Tropical Storm Eta brought wind and rain to the area around Tampa and St. Petersburg on Wednesday night. At 10:00 p.m. EST on Wednesday the center of Tropical Storm Eta was located at latitude 28.3°N and longitude 83.4°W which put it about 60 miles (95 km) west-northwest of Tampa, Florida. Eta was moving toward the north at 12 m.p.h. (19 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 993 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Boca Grande to Suwannee River, Florida. A Tropical Storm Warning was issued for the portion of the coast from the Flagler/Volusia County Line in Florida to St. Andrews Sound, Georgia. A Tropical Storm Watch was in effect for the portion of the coast from Suwannee River to Aucilla River, Florida.

Bands revolving around the eastern side of Tropical Storm Eta brought wind and rain to the area around Tampa and St. Petersburg on Wednesday night. One band stretched from Sarasota to Tampa and another band was over Clearwater and Tarpon Springs. Heavy rain was dropping over those areas and there were reports of urban flooding. Since the center of Tropical Eta was west-northwest of Tampa, southwesterly winds were blowing water into Tampa Bay. There were reports of storm surges of several feet around the bay.

An upper level trough over the Central U.S. will steer Tropical Storm Eta toward the northeast on Thursday. On its anticipated track Eta will make landfall between Tarpon Springs and Cedar Key in a few hours. The trough will steer Tropical Storm Eta across northeastern Florida and out over the Atlantic Ocean. Eta could still be a tropical storm when it reaches the Atlantic which prompted the issuance of a Tropical Storm Warning for the coast of northeastern Florida. Tropical Storm Eta could pass southeast of Charleston, South Carolina on Thursday night.

Elsewhere over the Atlantic Ocean, Tropical Storm Theta was moving south-southwest of the Azores. At 10:00 p.m. EST on Wednesday the center of Tropical Storm Theta was located at latitude 31.1°N and longitude 31.4°W which put it about 540 miles (865 km) south-southwest of the Azores. Theta was moving toward the east-northeast at 12 m.p.h. (19 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.

Eta Strengthens to a Hurricane, Hurricane Watch for Tampa

A NOAA plane found that former Tropical Storm Eta had strengthened back into a hurricane on Wednesday morning. A Hurricane Watch was issued for a portion of the west coast of Florida that included Tampa and St. Petersburg. At 7:35 a.m. EST on Wednesday the center of Hurricane Eta was located at latitude 25.8°N and longitude 83.8°W which put it about 170 miles (280 km) south-southwest of Tampa, Florida. Eta was moving toward the north-northeast at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 983 mb.

A Hurricane Watch was issued for the portion of the coast from Anna Maria Island to Yankeetown, Florida. The Hurricane Watch included Tampa and St. Petersburg. A Tropical Storm Warning was issued for the portion of the coast from Bonita Beach to the Suwannee River, Florida. The Warning included Tampa and St. Petersburg. A Tropical Storm Warning was also in effect for the Dry Tortugas. A Tropical Storm Watch was issued for the portion of the coast from the Suwannee River to the Aucilla River, Florida.

Former Storm Eta strengthened back to a hurricane on Wednesday morning, but it appeared to be moving back into a pool of drier air over the Gulf of Mexico. Thunderstorms increased around the center of Eta when it was over the warm water in the Loop Current on Tuesday, but the thunderstorms were weakening on Wednesday morning. Thunderstorms near the center of Hurricane Eta were not as tall as they were on Tuesday. The strongest thunderstorms were occurring in bands north and east of the center of Eta. Bands south and west of the center consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 115 miles (185 km) on the eastern side of Hurricane Eta. Winds to tropical storm force extended out 50 miles in the western half of the circulation.

Hurricane Eta will move through an environment marginally favorable for intensification on Wednesday. Eta will move over water where the Sea Surface Temperature is near 27°C. An upper level trough over the central U.S. will produce southwesterly winds which blow toward the top of Eta’s circulation on Wednesday. Those winds will cause vertical wind shear, but the shear may not be strong enough to prevent Eta from getting stronger. The drier air over the Gulf of Mexico will limit intensification. Hurricane Eta is not likely to intensify much more on Wednesday because of the drier air. The upper level trough will move closer to Eta on Thursday and the wind shear will increase. The shear and drier air will cause Eta to weaken after it makes landfall on the west coast of Florida.

The upper level trough will steer Hurricane Eta toward the north-northeast during the next 24 to 36 hours. On its anticipated track the center of Hurricane Eta could approach Tampa on Wednesday night. The center of Eta is forecast to pass just to the west of Tampa and make landfall north of Tampa. Eta could be near hurricane strength when it passes near Tampa. Southwesterly winds blowing around the east side of Tropical Storm Eta could push water into Tampa Bay. Eta could cause a storm surge of up to 7 feet (2 meters). Hurricane Eta will also drop heavy rain over Central Florida. Floods could occur in that area. Eta could also cause widespread power outages in Central Florida.

Elsewhere over the Atlantic Ocean, Tropical Storm Theta churned southwest of the Azores. At 4:00 a.m. EST on Wednesday the center of Tropical Storm Theta was located at latitude 29.4°N and longitude 34.7°W which put it about 740 miles (1190 km) southwest of the Azores. Theta was moving toward the east-northeast 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 989 mb.

Tropical Storm Eta Turns Back Toward Florida

Tropical Storm Eta tuned back toward Florida on Tuesday evening. At 10:00 p.m. EST on Tuesday the center of Tropical Storm Eta was located at latitude 23.8°N and longitude 84.5°W which put it about 120 miles (195 km) west-northwest of the Dry Tortugas. Eta was moving toward the north- northeast at 9 m.p.h. (15 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 992 mb.

A Tropical Storm Warning was issued for the portion of the coast from Bonita Beach to the Suwannee River, Florida. The Warning included Tampa and St. Petersburg. A Tropical Storm Warning was also in effect for the Dry Tortugas. A Tropical Storm Watch was issued for the portion of the coast from the Suwannee River to the Aucilla River, Florida.

The circulation around Tropical Storm Eta exhibited more organization on Tuesday evening. The inner end of a rainband wrapped around the the eastern and northern side of the the center of circulation. There were occasional indications that an eye could be forming at the center of Eta. Bands of showers and thunderstorms were revolving around the center of Tropical Storm Eta. There were more thunderstorms in the bands in the northeastern half of Eta. Bands in the southwestern half of the circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Tropical Storm Eta will move through an environment more favorable for intensification on Wednesday. Eta will move over water where the Sea Surface Temperature is near 28°C. An upper level trough over the central U.S. will produce southwesterly winds which blow toward the top of Eta’s circulation on Wednesday. Those winds will cause vertical wind shear, but the shear will not be strong enough to prevent Eta from getting stronger. Tropical Storm Eta could strengthen back into a hurricane on Wednesday. The upper level trough will move closer to Eta on Thursday and the wind shear will increase. The shear could get strong enough to cause Eta to weaken.

The upper level trough will steer Tropical Storm Eta toward the north-northeast during the next 24 to 48 hours. On its anticipated track the center of Eta will pass west of the Florida Keys on Wednesday. The center of Tropical Storm Eta could approach Tampa on Thursday morning. Eta could be near hurricane strength when it passes near Tampa. Southwesterly winds blowing around the east side of Tropical Storm Eta could push water into Tampa Bay. Eta could cause a storm surge of up to 7 feet (2 meters).

Elsewhere over the Atlantic Ocean, Subtropical Storm Theta nade a transition to a strong tropical storm. At 10:00 p.m. EST on Tuesday the center of Tropical Storm Theta was located at latitude 29.4°N and longitude 35.5°W which put it about 770 miles (1235 km) southwest of the Azores. Theta was moving toward the east-northeast at 12 m.p.h. (19 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 989 mb.
