PORTSMOUTH — A Nor’easter spinning its way up the New England coast will hit Portsmouth by Thursday night, bringing heavy rain and strong winds with it.

AccuWeather meteorologist Dave Samuhel said the Seacoast area can expect the storm to show up around 8 p.m. and dump 1 to 3 inches of rainfall as precipitation continues into Friday morning. AccuWeather acknowledged that rain pooling on the roadways and minor river flooding were possible, and Portsmouth could receive as much rain as any other spot on the Nor’Easter’s travel itinerary.

“It’s going to hit you guys head on,” Samuhel said. “It’s going to rain hard for a good six-to-eight hours.”

The storm should wrap up by late morning on Friday, he said, when it
will begin to impact areas such as Portland, Maine. Winds throughout the storm area are expected to reach 20 to 25 miles per hour.

The National Weather Service forecast as of 1 p.m. Thursday was much milder, calling for between an inch and inch and a half of rain
through Friday.

Lets see what happens. Mr Choate did acknowledge the milder forecast in his article. I can’t find my rain gauge, it is probably with my flow meter. The higher rain forecast means the boat may need a midnight bilge pump, the lower, it can wait till morning.
