The last of the severe thunderstorm warnings for Long Island expired at 8 p.m. Monday after a system with torrential rain and strong gusts moved through the area, the National Weather Service said.

Gusts of 39 mph were reported in Islip about 3 p.m., before the heavy rain, and both the wind strength and the chance of rain were expected to fall overnight, the service said.

But it appears Long Island escaped the worst of the storm, said Jay Engle, a National Weather Service meteorologist based in Upton.

The brunt of the rain and winds was felt in New York City and areas west and north of the Island, he said.

“They weakened as they moved east,” Engle said of the storms.

Nassau and Suffolk police said they did not have any reports of major damage and flooding, but the Long Island Rail Road reported weather-related signal problems on the Hempstead branch. It started just before 8 p.m. east of Garden City and had delayed four trains by 8:22 p.m. Crews were at the scene, LIRR said.

The Federal Aviation Administration also had reported weather-related delays at Kennedy and LaGuardia airports.

News 12 meteorologist Matt Hammer said Tuesday will be sunny: “A few showers may linger for the East End of Long Island early Tuesday,” Hammer said. “However, Tuesday will become mainly sunny with lower humidity.”

Highs in the low 80s are expected.

Wednesday should bring mostly sunny skies, then a slight chance of afternoon showers, also with highs in the low 80s, the weather service said.
