Flooding Risk Expands Into Mid-Atlantic, South

A swath of slow-moving showers and thunderstorms will gradually push into the mid-Atlantic into Tuesday.

Torrential downpours associated with the thunderstorms could result in flash flooding and travel delays for people from parts of Kentucky and Tennessee to portions of Virginia and North Carolina through Tuesday morning.

This includes portions of the I-40, I-81, I-85 and I-95 corridors; however, the showers and storms are forecast to stay south of the cities of Philadelphia and Baltimore, and graze Washington, D.C.

AccuWeather Senior Meteorologist Kristina Pydynowski warns that these storms can create travel delays as they move through, especially on the roadways. This includes the commutes through Tuesday morning.

"Even if flooding fails to ensue, the downpours would create hazards to motorists by dramatically reducing visibility and heightening the risk of vehicles hydroplaning at highway speeds," Pydynowski said.

Remember that if you come across a flooded roadway it is dangerous to drive through it. The water may be deeper than it appears and can carry your vehicle with the current.

It takes less than 2 feet of rushing water to lift and move a car. Turn around, don't drown.

The system responsible for these showers and thunderstorms already has a history of flooding.

On Sunday, slow-moving thunderstorms dumped over 5 inches of rain on the town of Skullbone, Tennessee, which resulted in flash flooding in surrounding areas.

Downpours such as this are possible through Tuesday morning across the lower part of the mid-Atlantic, especially over the Appalachian Mountains.

Another round of showers and thunderstorms is expected to dive southward into the mid-Atlantic later in the week, delivering more rain to the mid-Atlantic.

"As yet another batch of showers and storms moves in from the Midwest, the risk of disruptive downpours will expand northward across the mid-Atlantic during Wednesday into Friday," said AccuWeather Senior Meteorologist Alex Sosnowski.

These showers and thunderstorms can bring disruptions to outdoor activities and possibly more travel delays.
