Hurricane Idalia intensified steadily during Tuesday afternoon. A circular eye with a diameter of 30 miles (50 km) was at the center of Idalia’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 Idalia’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Idalia grew larger when Idalia intensified. Winds to hurricane force extended out 25 miles (40 km) from the center of Idalia’s circulation. Winds to tropical storm force extended out 160 miles (260 km) in the eastern side of Hurricane Ida. Winds to tropical storm force extended out 70 miles in the western side of Ida’s circulation. The Hurricane Intensity Index (HII) for Hurricane Ida was 16.5. The Hurricane Size Index (HSI) was 8.0 and the Hurricane Wind Intensity Size Index (HWISI) was 24.5.

Hurricane Idalia will move through an environment that will be favorable for intensification during the next 12 hours. Idalia will be over water where the Sea Surface Temperatures are near 30°C. It will move into a region between an upper level ridge over the Yucatan Peninsula and an upper level trough over the central U.S. The upper level winds are weaker between the ridge and the trough and there will be little vertical wind shear during the next 12 hours. The upper level winds will be stronger when Idalia moves closer to the upper level trough on Wednesday morning. Hurricane Idalia will intensify during the next 12 hours. Idalia could rapidly intensify at times. Hurricane Idalia is likely to strengthen to a major hurricane.

Hurricane Idalia will move around the western end of high pressure system over the western Atlantic Ocean. The high pressure system and the upper level trough over the central U.S. will steer Idalia toward the north-northeast during the next 12 hours. The upper level trough will turn Idalia toward the northeast on Wednesday. On its anticipated track, Hurricane Idalia will likely to make landfall on the coast of the northeast Gulf of Mexico on Wednesday morning. Idalia is likely to make landfall as a major hurricane.

Hurricane Idalia is forecast to be a major hurricane when it reaches the coast of Florida. Idalia could be similar in size and intensity to Hurricane Dennis when Dennis hit Northwest Florida in 2005. Hurricane Idalia is likely to make landfall in an area where high storm surges can occur. Idalia could cause a storm surge of up to 15 feet (4.5 meters) near where the center makes landfall. A Storm Surge Warning has been issued for the portion of the coast from Englewood to Indian Pass, Florida. The Storm Surge Warning includes Tampa Bay. Hurricane Idalia will bring strong winds and heavy rain to parts of central and northern Florida. Idalia will be capable of causing major damage over parts of northern and northeastern Florida. Widespread outages of electricity are likely. Heavy rain could cause flash floods in some locations. Strong winds and heavy rain will spread over eastern Georgia, South Carolina and North Carolina when Idalia moves toward the northeast. Flood Watches are in effect for parts of northern Florida, eastern Georgia, South Carolina and North Carolina.

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.

Tropical Storm Ian began to intensify quickly on Sunday evening. Microwave satellite images indicated that an eye was forming at the center of Ian’s circulation. The developing eye was surrounded by broken ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of Tropical Storm Ian. Storms near the center of circulation generated strong upper level divergence that pumped large quantities of mass away from the tropical storm. The removal of mass was allowing the surface pressure to decrease rapidly. Winds to tropical storm force extended out 70 miles (110 km) from the center of Ian’ circulation.

Tropical Storm Ian will move through an environment very favorable for intensification during the next 36 hours. Ian will move over water where the Sea Surface Temperatures are near 30˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Ian is likely to intensify rapidly during the next 36 hours. Ian is likely to strengthen to a hurricane during the next 12 hours. Ian is likely to intensify to a major hurricane during the next 36 hours.

Tropical Storm Ian will move around the western end of a high pressure system over the western Atlantic Ocean. The high pressure system will steer Ian toward the northwest during the next 24 hours. Ian will move toward the north when it reaches the western end of the high pressure system. On its anticipated track the center of Tropical Storm Ian will pass west of Grand Cayman on Monday. Ian could be near western Cuba on Tuesday morning. Ian could be a major hurricane when it approaches western Cuba. Ian could be southwest of Tampa, Florida on Wednesday afternoon.
