Strong Thunderstorms COULD Affect Delmarva Today

Jun 18, 2013 -- 6:51am

Accu Weather says the risk of flash flooding will expand from the South into the mid-Atlantic today, threatening Atlanta, Georgia, Raleigh, North Carolina and Philadelphia.

Forecasters say an area of low pressure moving from the Tennessee Valley toward the Chesapeake Bay will pull warm, moisture-rich air from the South, providing fuel for heavy thunderstorms this afternoon into tonight. This is the same system that spread flooding thunderstorms across the South on Monday, causing rivers and creeks to jump their banks and roads to close due to high water.

While the threat for flash flooding is widespread, the heaviest rain will be centered from southern Virginia to central North Carolina. In this area, thunderstorms may produce 1-3 inches of rainfall.

Although the highest rainfall totals will be focused on this area, heavy thunderstorms elsewhere can still easily produce over an inch of rain in less than an hour, leading to flash flooding.
