A low pressure system designated as Invest 90L will drop heavy rain over parts of Central and South Florida during the next 24 hours. At 2:00 p.m. EDT on Tuesday the center of Invest 90L was located at latitude 26.9°N and longitude 93.9°W which put it about 75 miles (120 km) west-southwest of Sarasota, Florida. The low pressure system was moving toward the east-northeast at 13 m.p.h. (20 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 1009 mb.

A low pressure system developed over the eastern Gulf of Mexico on Tuesday. The low pressure system was designated as Invest 90L. It was approaching the west coast of Florida near Sarasota on Tuesday afternoon. The low pressure system was being steered toward the east-northeast. It will move across the Florida Peninsula during Tuesday night. The low pressure system will drop heavy rain over parts of Central and South Florida.

A Flood Watch was in effect for South Florida.

A well defined low level circulation was visible on satellite images. Thunderstorms were occurring in the eastern and northern parts of the low pressure system. Thunderstorms were also occurring in a band just east of the center of circulation. Bands north and west of the center of the low pressure system consisted primarily of showers and lower clouds.

The low pressure system will move through an environment unfavorable for the formation of a tropical cyclone during the next 24 hours. The low pressure system will move over water where the Sea Surface Temperatures are near 30°C during the next few hours. Then it will move over the Florida Peninsula. An upper level trough over the eastern U.S. will produce westerly winds that will blow across the top of the low pressure system. Those winds will cause strong vertical wind shear. The combination of movement over land and strong vertical wind shear is likely to prevent the development of a tropical cyclone during the next 24 hours.

The low pressure system could move into a more favorable environment when it moves over the western Atlantic Ocean on Friday. The upper level trough could move northeast of the low pressure system which would cause the vertical wind shear to decrease. The U.S. National Hurricane Center is indicating that probability is 20% that the low pressure system develops into a tropical cyclone after it moves over the western Atlantic Ocean northeast of Florida.

The upper level trough will steer the low pressure system toward the east-northeast during the next 24 hours. On its anticipated track the low pressure system will reach the west coast of Florida near Sarasota in a few hours. The center of the low pressure system is likely to pass south of Orlando and Daytona Beach. It will drop heavy rain over parts of Central and South Florida. Some thunderstorms could approach severe criteria.
