Tropical depression Bonnie, now over Louisiana and western Mississippi. Bonnie’s remnants are producing scattered showers and thunderstorms today and tonight in those areas.

At 8:30 a.m. EDT (7:30 a.m. CDT) Bonnie’s remnants generated an area of showers and thunderstorms north of Lake Pontchartrain in eastern Louisiana and western Mississippi. One of the thunderstorms spawned a tornado warning for Wathall and Washington Counties in western Mississippi at that time.

Bonnie’s center is located inland south of New Orleans, Louisiana, and the bulk of the showers and thunderstorms associated with it are mainly to the west and north of the remnant low’s center.

The National Weather Service in New Orleans has issued a Coastal Flood Advisory in effect until 7 p.m. CDT this evening. The remnant low pressure formerly known as tropical depression Bonnie is moving inland across Louisiana today. Moderate to strong south to southeast winds near the coast will diminish today. Tides however will remain as much as two feet above normal over Hancock County Mississippi and the east facing coastal areas of southeast Louisiana.

Winds out of the southeast in the area of Bonnie are not because of the remnant low, but because of the high pressure area over the Gulf. Winds are expected to be light today, between 5 and 10 mph shifting to the south.

The National Weather Service forecast for New Orleans today, Sunday, July 25 includes showers and thunderstorms today and tonight with hot and humid conditions. The high is expected near 92, but the humidity will bring the heat index to 105 Fahrenheit today.

The National Hurricane Center noted that “Regeneration is not expected as the system moves northwestward at about 10 mph. There is a low chance…near 0 percent…of this system becoming a tropical cyclone during the next 48 hours.”

Tropical Storm Bonnie Disorganized Over South Florida

Tropical Storm Bonnie was crossing over south Florida at 11 a.m. EDT today, July 23, and it is being battered by strong wind shear. Satellite and radar data have indicated that the center of Bonnie’s circulation is southeast of the strongest convection and showers, which are currently located over southeastern Florida.

Eye on Bonnie as she tracks across Florida today. At 1625 UTC (12:25 p.m. EDT), GOES-13 visible imagery showed the bulk of Bonnie’s clouds over south Florida, although her center is southeast of there. GOES is operated by the National Oceanic and Atmospheric Administration, and NASA’s GOES Project, located at NASA’s Goddard Space Flight Center, Greenbelt, Md. creates some of the GOES satellite images.

At 11 a.m. EDT, Bonnie’s center was near 25.4 North and 80.3 West, about 30 miles south-southwest of Miami, Fla. and 130 miles southeast of Fort Myers, Fla. Bonnie’s maximum sustained winds remain near 40 mph, and she’s moving west-northwest near 18 mph. Bonnie is expected to produce total rain accumulations of 1 to 3 inches over south Florida with possible isolated maximum amounts of 5 inches.
