Post Tropical Storm Andrea is racing northeast at 28 mph. Andrea is producing gusty winds to 45 mph and heavy rainfall. The center of circulation is located near the North Carolina-Virginia border with a rain shield extending well northeastward. Moisture streaming in from the Atlantic was interacting with a frontal boundary over the area and enhancing rainfall.
Andrea has produced an axis of heavy rain that extends 50-80 miles inland along the Georgia and North and South Carolina coasts. Generally, a widespread 2- to 5-inches of rain has fallen within this area, with pockets of rainfall in the 6- to 8-inch range (red-shaded areas). Isolated amounts are likely to exceed 8 inches.
Heavy rain will continue over the Mid Atlantic and Northeast U.S. as Andrea pushes northeast tonight and Saturday. Here is a forecast for rain within this region. While Andrea will continue to weaken, it can still produce a lot of heavy rainfall. Fortunately, a progressive forward speed will limit total rainfall amounts.
Coastal and inland flooding is possible due to the heavy rain. Potential impacts will include.
Pooling of water within low and poorly-drained spots
Main stem river flooding
1. Potential main stem river flooding.
