Just as Long Islanders finally dry off from Thursday's deluge, which dumped several inches across the region and created flash flood conditions . . . here comes the rain again.

Scattered showers dotted the Island beginning around 5 p.m. Heavier rain and thunderstorms were expected overnight, said Carlie Buccola, a meteorologist with the National Weather Service in Upton.

A waterspout was spotted off Long Beach shortly after 5 p.m. as dark clouds and scattered showers swept over Nassau and western Suffolk counties.

The waterspout was seen about a mile offshore, with winds of about 30 mph. The funnel cloud was the same formation as a tornado, but was expected to break up before moving on shore, Weather Service meteorologist Faye Barthold said.

"There's less friction over water, so it breaks up the circulation when it moves over land," Barthold said. "If you're on a boat, there are pretty strong winds and coming from different directions and more danger in the water."

Additional waterspouts were expected later Saturday night with stronger storms in the Atlantic, but not expected to make landfall. The storm was expected to bring about a half-inch of rain to Long Beach.

Temperatures Saturday touched the low 80s before they were forecast to drop into the mid 60s overnight, Buccola said.

The rain will continue through the first part of Sunday before finally tapering off after 3 p.m., Buccola said. Sunday's forecast calls for temperatures in the mid to upper 70s and falling into the upper 50s overnight.

Monday's forecast looks dry with temperatures reaching the upper 70s.
