A severe thunderstorm warning in effect for Suffolk County has been lifted, according to the National Weather Service.

Shortly after 3 p.m., thunderstorms "capable of producing damaging winds in excess of 60 mph" were located along a line from Northport to Port Jefferson and moving east at 30 mph, the weather service said.

The warning was lifted at 3:36 p.m. as those storms weakened, said Peter Wichrowski, weather service meteorologist.

Still, forecasters were "keeping an eye on" showers and thunderstorms to the west -- activity that should head east and move out by about 10 p.m., Wichrowski said.

Earlier Friday, the weather service predicted heavy rainfall during the day and into the night, as a cold front moves through Long Island.

"Localized flash flooding is a possibility with any thunderstorms that develop," the weather service said in a statement.

The weather was causing arrival delays averaging a little more than an hour at LaGuardia and Kennedy airports.

Gusty winds could accompany some of the storms, the weather service said. The chance of precipitation is 70 percent, and the high temperature will be in the low 80s.

In addition, there's a high rip current risk at ocean beaches, where the surf height will be 3 to 5 feet, the weather service said.
