More Flooding Downpours Along Interstate 95 Friday

Persistent downpours and thunderstorms will continue to bring the threat for flash flooding across the mid-Atlantic and Southeast Friday as a stalled front sits nearby.

Flooding may impact Washington, D.C., Philadelphia, Pa., Richmond and Norfolk, Va., Raleigh, N.C., Charleston, S.C., and Jacksonville, Fla.

The heaviest downpours will produce over an inch of rain per hour, which will lead to flooding along streets, highways and areas of poor drainage. Some roads may even become impassible due to high water.

The heavy rainfall rates can also push small streams and creeks out of their banks, many of which are already swollen thanks to recent heavy rain.

The most numerous showers and thunderstorms should develop from eastern Florida up to Virginia and the Washington, D.C., area.

Heavy rain already pounded much of the Washington area Thursday night, leading to flooded roadways and even a handful of water rescues. It will not take much rain to cause additional flooding problems on Friday.

Farther north and east, the showers will not be as widespread around the Philadelphia area, but any shower or thunderstorm can produce a flooding downpour in any given location.

The ground is already saturated in many areas from recent rainfall. Streams and creeks from eastern Georgia to Virginia are already near or above flood stage. Any additional rainfall will only act to exacerbate existing flooding problems.

One example of the recent heavy rain is Greenville, S.C. Measurable rain has been recorded through each of the first 11 days of the month, totaling 10.19 inches. That total is already more than double the average of 4.80 inches for the entire month of July.

The flooding threat will persist into Saturday and spread into the central and southern Appalachians as the energy helping to fuel the storms drifts west. The moisture from Tropical Rainstorm Chantal will also help to enhance the rainfall, especially across the Carolinas and eastern Virginia.

The good news for these rain-soaked areas is that the showers and thunderstorms will not be nearly as widespread by Sunday and early next week, allowing more opportunities to dry out.
