The National Weather Service issued a flood watch for central and southern New Hampshire in anticipation of continued warm temperatures this week, along with heavy rain.

The watch issued Sunday afternoon is for Tuesday and Wednesday, when as much as an inch-and-a-half of rain could fall and overnight temperatures are expected to remain above freezing, meteorologist Bob Marine of the National Weather Service said Sunday.

“The main concern is ice-jam flooding because it looks like we’re going to get a fair amount of rain,” Marine said from the NWS station in Gray, Maine. “Some of the rivers have been aggravated from that last system. There are already several ice jams remaining on some rivers and water levels are staying fairly high in some of them.”

One of the biggest concerns was in New Boston, where an ice jam on the Piscataquog River continues to grow.

Temperatures climbed into the high 40s again on Sunday, melting more of the remaining snow from last weekend’s storm.

Marine said overnight temperatures have been dropping back below freezing, slowing the melting and reducing the runoff, but that is expected to change this week, just in time for the rain.

“It’s just going to aggravate the situation,” Marine said.
