Drenching and gusty thunderstorms threaten to ruin weekend plans up and down the East Coast into this evening.
Today started with heavy thunderstorms rattling the central Gulf Coast, leading to flooded and impassible streets in North Slidell, La., early this morning.
Other streets and highways could face a similar fate into this evening as additional drenching thunderstorms rumble along the corridor from Savannah, Ga., to Norfolk, Va., to New York City to Boston, Mass., to Lebanon, N.H., and Portland, Maine.
Rainfall rates of an inch or more an hour in some of the thunderstorms through this evening will easily overwhelm storm drains, causing water to flood streets and basements.
Water could pond on roadways, significantly heightening the risk of vehicles hydroplaning when traveling at highway speeds.
In any downpour, it is better to seek shelter than use your umbrella if lightning is also present.
Even where flooding does not ensue, motorists should use caution as the downpours will dramatically reduce visibility.
Heavy bursts of rain could also lead to flooding of low-lying, poor drainage and urban areas.
