Heavy rain pounded Long Island throughout Sunday, leaving hundreds without power, though largely sparing the area from other storm-related damage, said meteorologists with the National Weather Service.

Parts of Nassau and Suffolk reported receiving a half-inch of rain after two rounds of showers hit the region — an early morning storm system crept over the area and was followed by more rain in the evening. The evening system entered Nassau County at about 6 p.m. and was expected to exit Long Island’s East End by midnight, officials with the Upton-based National Weather Service said.

“We didn’t receive any reports of damage on Long Island,” said Joe Pollina, a meteorologist with the service.

Islip reported 0.56 inches of rain, while Farmingdale reported 0.58 inches of rain, Pollina said.

“Nothing too serious, and it was well needed,” Pollina said of the precipitation amounts.

The earlier rain showers led to power outages at hundreds of homes during the day that were largely restored by Sunday evening, according to the PSEG Long Island website.

About 3 p.m., PSEG Long Island officials reported 1,124 customers without electricity.

But by about 9 p.m., that number had dropped to 39 customers, according to the company’s website.

The start of the work week on Monday will bring a break from the unsettled weather when highs will climb to around 80.

“We dry out and it’ll be mostly sunny,” Barthold said. Nighttime lows will be in the mid-60s.

Highs in the upper 70s are ahead for Tuesday when it will be partly sunny, but a chance of showers is forecast from noon until about 6 p.m. Lows are expected to be around 60.

On Wednesday, highs will be in the low to mid-70s under mostly sunny skies; lows will drop to the mid-50s.

“Thursday stays mostly dry,” Barthold said. “It’ll be sunny again, with highs in the low to mid-70s and lows at night in the mid-50s.”

Highs in the mid-70s start the weekend on Friday, when lots of sun returns and lows will be around 60.

Barthold said the average temperatures for the week would be highs in the mid-70s and lows in the mid-50s.
