Flooding downpours will return to the mid-Atlantic and Northeast on Monday, targeting areas just hit by Andrea. Washington D.C. to Philadelphia to New York City and Boston will be among a host of other cities threatened.
Numerous showers and thunderstorms will move into the interior Northeast by Monday morning before advancing toward the coast into the evening.
The wet weather is in response to an advancing storm fueled by humid air.
Andrea shattered June rainfall records late last week across the mid-Atlantic and southern New England. This will make the region extremely vulnerable to flooding on Monday as downpours return.
The morning commute will be mainly rain-free across the Interstate 95 corridor from Washington to New York City, however the evening commute can be complicated by flash flooding.
Numerous downpours will extend into the region by the evening commute and can quickly flood small streams and overtake storm drains in the region. Ponding on roadways will be widespread in the region, particularly in urban areas.
Any travelers that encounter water covered roadways are urged to stop and turn around. Residents in low-lying areas near small streams should be especially vigilant as these downpours cross the region.
The heaviest rain will move farther north into southern New England by Monday night. Cities such as Hartford, Conn. to Providence, R.I. and Boston will be threatened by flash flooding.
Downpours will persist into Tuesday across the region, but they will be far less frequent. Nonetheless, an isolated flash flood threat will persist through at least early Tuesday night. While the remainder of the week will not be a washout for most, more rain will hit the region from time to time.
