Florence's Remnants Will Bring a Soaking Rain, Possible Flooding to the Northeast Early This Week

While Florence will continue to dump heavy rainfall from the Carolinas into western Virginia and eastern West Virginia through early Monday, its remnants will eventually get steered northward into the Northeast later Monday and into Tuesday, which may lead to some areas of flooding.

An upper-level area of high pressure northwest of Florence will shift eastward over the next day or so, allowing Florence's remnants to finally get steered northward out of the Appalachians and into the Northeast later Monday and into Tuesday. This will bring a threat of heavy rainfall to much of the Northeast.

Rain should develop by Monday morning from western Pennsylvania into western New York, gradually spreading north and eastward through the day. The rain will reach the Interstate 95 corridor and most of New England by Monday night.

The steadiest, heaviest rain is expected Monday night and into Tuesday across much of the Northeast. Rainfall rates on the order of 1 to 2 inches per hour are possible at times.

There is still some uncertainty on the exact track of Florence's remnants, but a widespread area of 1 to 3 inches of rain is possible Monday into Tuesday.

Localized areas could see more than 3 inches of rain, with the best chance of this occurring in eastern New York and central New England.

Northeast Rainfall Forecast

The main concerns are expected to be flash flooding and flooding along smaller streams and creeks. At this time, the concern for mainstem river flooding is low.

It should also be noted that there could be some stronger thunderstorms associated with the rain, potentially packing a threat of gusty winds.

Florence's remnants should push off the coast of the Northeast by Wednesday, leading to drier weather for the middle of the week.
