With rain falling nearly all day and evening on Saturday, the National Weather Service has issued flood warnings for four New Hampshire rivers — warnings that could last through the weekend.

NWS Meteorologist John Cannon said forecasts call for an inch of rain in most parts of the state on Saturday and up to two inches in some parts of the White Mountains.

“(Sunday) there will be a few leftover showers but most of the rainfall is going to be from Saturday until Saturday evening,” he said, adding that temperatures will likely remain in the 60s throughout the state.

The warm weather is melting snow, which is combining with the rainfall to create flooding situations.

“Most of it will be minor flooding,” Cannon said.

The NWS issued the following flood warnings on Saturday: the Ammonoosuc River at Bethlehem until late Saturday night; the Androscoggin River at Gorham until Satuday evening; the Connecticut River near Dalton and Wells River until further notice; the Connecticut River at North Stratford until Sunday morning; the Pemigewasset River at Woodstock until Sunday afternoon; the Pemigewasset River at Plymouth until Sunday night; and the Saco River at Conway until late Sunday night.

“A flood warning is issued when flooding is imminent or already occurring,” Homeland Security & Emergency Management Assistant Director Jennifer Harper said in a statement. “If advised to evacuate, do so immediately.”

To the south, thunderstorms caused the death of at least three people.

In Neshoba County, Miss., a tree fell on a man’s car, killing him, according to Reuters. There were also reports of trees falling on homes in St. Clair County, Miss., and Wattsville, Ala., which also resulted in deaths.
