The forecast computer model shows strong low pressure (red “L”) that could bring severe weather to the south and heavy rain to the east.
Below, we have details on what we know now about the severe weather, heavy rains and high wind risks this storm poses to the South.
The Gulf Coast and Southeast may see severe weather on Monday and Tuesday: Increasing moisture from the Gulf of Mexico ahead of a strong low pressure system will gradually increase the chance of severe storms Monday and Monday night.
This threat could extend from the Texas coast eastward to southern parts of Louisiana, Mississippi, and Alabama as well as the Florida Panhandle. Houston, New Orleans and Mobile, Alabama, are among the cities at risk.
Damaging winds and some tornadoes are possible in all of these areas.
Monday night into Monday severe thunderstorms forecast
On Tuesday, the threat is spreading eastward from north and central Florida into southeastern Alabama, central and southern Georgia as well as parts of the Carolinas. Tampa, Jacksonville and Charleston, South Carolina, are some areas that could see severe weather.
Destructive straight-line winds and a tornado threat can accompany any severe storms.
Tuesday Night – Tuesday Severe thunderstorms forecast
The storm can also produce flooding and strong winds: Flash flooding will be possible in the south Monday into Tuesday as a Finnish cold front crosses the region. Rainfall totals for most areas will range from 1 to 3 inches, but some locations may reach 3 to 5 inches.
The central Gulf Coast will face its greatest flooding threat Monday and Monday night. Parts of the southern Appalachian Mountains and neighboring Piedmont face an increased risk of flooding on Tuesday.
Strong winds will spread from the Midwest and South during the day on Tuesday to the East Coast on Tuesday and Wednesday night.
Strong storms in these areas may cause some tree damage and/or power outages even in areas without severe thunderstorms.
