Rain, Mild Weather to Bring Flooding Risk to Northeast

Rain and melting snow will raise the risk of stream, river and ice jam flooding in parts of the Northeast this weekend.

According to AccuWeather Chief Meteorologist Elliot Abrams, "Parts of upstate New York, northern Pennsylvania and New England can receive a few inches of rain this weekend."

A slow-moving storm, the second of two systems since Friday, will roll through the area Saturday into Sunday.

"There is a substantial amount of snow on the ground in the northern reaches of the Northeast," Abrams said.

While some of the snow will melt with few problems, where ice breaks loose and then jams up on area streams and rivers, there is greater risk for flooding.

"The combination of a couple of inches of rainfall and several inches of water locked up in snow and ice can unleash a half a foot of water onto areas along small streams that then feed into rivers," Abrams said.

Flooding along some small streams is likely this weekend, along with significant rises possible in the following days along some of the major rivers including the Susquehanna, Delaware, Chenango, Connecticut, Mohawk, Walloomsac, Merrimack, Kennebec and Penobscot.

Generally the larger the river, the longer it takes for high water to cycle through.

Some snow or a wintry mix will fall over some of the northern tier areas and highest elevations of the central Appalachians with the storm. This precipitation will tend to slow the runoff.

However, the thaw will continue, resume or expand into next week, keeping some streams and rivers running high.

Temperatures are forecast to reach the 40s and 50s in the northern tier states of the Northeast next week.
