The tropical weather system moving across the Florida Panhandle on Wednesday was showing a greater chance of becoming a tropical depression as it moves toward the northern Gulf Coast, according to the National Hurricane Center.
The weather system has a 40% chance of becoming a tropical depression as it moves west toward southeastern Louisiana on Thursday, the federal agency said. The tropical weather will affect Alabama and Mississippi as well.
Regardless of whether the system worsens, heavy downpours could cause flooding, officials warned.
New Orleans is bracing for three to five inches of rain through Saturday, but some localized areas could see more than eight to 10 inches, especially near the coast, the National Weather Service said.
“While a tropical depression cannot be ruled out near the coast on Thursday, the main focus remains the heavy rain threat,” the agency wrote on X.
The looming threat in the southeast comes on the heels of a series of lethal floods this summer. On Monday, flash floods inundated New York City and parts of New Jersey, claiming two lives. And at least 132 people were killed in floodwaters that overwhelmed Texas Hill Country on the Fourth of July.
The current system percolating over Florida would be called Tropical Storm Dexter if it becomes a named storm. Just six weeks into the Atlantic hurricane season, which runs from June 1 to Nov. 30, there have been three named storms: Andrea, Barry and Chantal. Dexter would be the fourth if it develops that way.
Chantal made landfall in South Carolina last week, and its remnants caused flooding in North Carolina that killed an 83-year-old woman when her car was swept off a rural road.
The National Oceanic and Atmospheric Association said there was a 60% chance that there will be more named storms this hurricane season than there have been in past years on average.
The currently developing weather system is expected to move fully inland by the end of the week.
