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.

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.
