Debby has resulted in heavy rainfall and flash flooding overnight, especially across portions of the Lowcountry where 24-hr rainfall of 6-10″ has been widespread in the vicinity of I-95 between Savannah and Charleston.  In their latest discussion, the Weather Prediction Center states that over the next few hours, some of the rain bands could briefly produced 4″ of rain in just an hour.  6-hour rainfall could be 3-5″ or more. Flash flooding is likely, some of which maybe significant to locally catastrophic. 

Here is the latest discussion graphic, followed by a few scenes out of Charleston, SC from this morning.

Future of Debby:

The main concern moving forward is the rain and potential for massive flooding.

The center of Debby could crawl offshore the GA coast late today and then hang out just off shore through early Thursday. That is an awful scenario as rain bands fueled with tropical moisture pull into the southeast coast and bring in the tremendous flooding.

A ridge over the western Atlantic and a trough over the upper Midwest final give Debby the push needed to move and move more quickly. A track through North Carolina and into Virginia expected by week’s end and by late Saturday night/early Sunday, the center of Debby (moving extratropical at that point) is forecast to be off the New England Coast.
