Cindy will continue to release torrential rainfall and raise the risk of flooding even as the storm moves well inland over the United States into this weekend.
"After moving inland, winds associated with Cindy will diminish and the system will eventually be dubbed a tropical rainstorm," according to AccuWeather Hurricane Expert Dan Kottlowski.
However, just as flooding is the greatest threat to lives and property along the Gulf coast, so will be the case farther inland.
The combination of saturated soil, heavy rain and hilly terrain can lead to dangerous flash flooding.
In flat terrain, water will collect on area streets and highways and can lead to difficult travel. Motorists will need to seek an alternate route.
A general 2-4 inches of rain is forecast to fall over parts of the lower Mississippi, Tennessee and Ohio valleys, as well as the southern Appalachians on top of what falls through Wednesday.
Cindy, as a tropical rainstorm, will interact with an approaching push of cooler air from the north. Exactly where this occurs, excessive rainfall can occur.
Localized rainfall of 6-8 inches is possible along this interaction zone from Thursday night through Saturday.
At this time this zone of torrential rainfall is likely to develop in parts of Kentucky and Tennessee and progress eastward through portions of Ohio, West Virginia, Virginia and Maryland.
"Farther south, in Louisiana, Mississippi, Alabama, Georgia, Florida, South Carolina and North Carolina, a plume of tropical moisture will continue to fuel rounds of showers and thunderstorms," according to AccuWeather Senior Meteorologist Ken Clark.
"These additional downpours in the South can continue flooding at the local level along the Interstate-10 and 20 corridors during Friday and this weekend," Clark said.
Never attempt to drive through flooded roads or cross barricades placed by emergency personnel. The road may have been compromised beneath the water. As little as a couple of feet of water can cause a vehicle to temporarily float and be carried downstream.
In mountainous terrain along secondary roads, motorists should be on the lookout for falling debris and washouts.
It may not be until next week before much of the South dries out.
