Cindy’s major flood threat to persist as storm unleashes up to a foot of rain

 Cindy will continue to release torrential rainfall and raise the risk of flooding even as the storm pushes well inland over the United States into this weekend.
Just as flooding is the greatest threat to lives and property along the Gulf coast, so will be the case farther inland.
Static Cindy Inland Flood Risk Friday to Saturday morning

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 part of the central Appalachians and mid-Atlantic through Friday night.
Cindy, as a tropical rainstorm, will interact with an approaching push of cooler air from the north. At the local level, 4-8 inches of rain can fall, which will enhance the risk of flooding.
People in this area should be alert for rapidly rising water on streams, which can flood adjacent roadways.
Only the increasing forward speed of the tropical feature will shorten the duration of the rain and may limit the flooding to isolated areas.
"The most likely time for torrential downpours and urban flooding from Washington, D.C., to Philadelphia and New York City is late Friday night into early Saturday," according to AccuWeather Senior Meteorologist Dave Dombek.

"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.
Static South Dries Out Early Next Week

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.
