NORTHAMPTON — The National Weather Service has extended a flood warning for the Connecticut River at Northampton until early Friday morning.

At 1 p.m. Tuesday, the river was 2 feet above flood stage at 114 feet, the weather service stated. It is not expected to fall below flood stage until Thursday evening.

High water is affecting the Oxbow in Northampton, including Riverside Homes on Island Road, as well as parts of Hadley, according to the weather service. In Hatfield, back water from the Connecticut River will push the Mill River over its banks, flooding parts of Valley Street and surrounding areas.

The Connecticut River has also reached minor flood stage upstream at Montague.

Much of the Northeast endured a windy storm Sunday and Monday that dumped 2½ to 3 inches of rain and cut power to hundreds of thousands across the region amid unseasonably balmy temperatures.

Maine State Police were looking Tuesday for two people whose car was swept away by floodwaters. Some towns in Vermont, which had suffered major flooding from a storm in July, were seeing more flood damage. Seventeen people were rescued from floodwaters in Conway, New Hampshire, four of them by helicopter.

More than 5 inches of rain fell in parts of New Jersey and northeastern Pennsylvania, and parts of several other states got more than 4 inches, according to the National Weather Service. Wind gusts reached nearly 70 mph along the southern New England shoreline.

During the storm Monday, an 89-year-old Hingham man was killed when high winds brought a tree down on a trailer, authorities said. In Windham, Maine, police said, part of a tree fell and killed a man who was removing debris from his roof. Another man in Fairfield, Maine, died while trying to move a storm-downed tree with a tractor, news outlets reported.
