Thousands of households in the New York region, mainly on Long Island, were without power Sunday as winds gusting more than 50 miles per hour continued to sweep through the area for a second day.

Wind gusts of 40 to 50 mph and sustained winds of 30 to 40 p.m. were forecast for the metropolitan region through 7 p.m. Sunday, said John Murray of the National Weather Service.

Bert Cunningham, a spokesman for the Long Island Power Authority, said 4,701 customers, or about 12,900 people, were without power on the island Sunday morning. Officials blamed falling trees for downing power lines.

He said crews were working 16-hour shifts to restore power.

LIPA had reported that 78,683 customers — about 228,000 people — were without power Saturday.

Consolidated Edison reported scattered outages Sunday, mainly in Westchester County, where 115 customers were without power, spokesman Alfonso Quiroz said. About 50 customers in New York city were without power, he said.

NWS meteorologist John Cristantello said the high winds were caused by a stronger-than-normal low pressure system that passed through Pennsylvania and New York on its way to southeastern Canada.

Saturday's winds were accompanied by on-and-off rainstorms that dropped 2.54 inches on Central Park.

No rain was forecast for Sunday in the metropolitan region, and meteorologists predicted a warming trend for Monday and Tuesday with sunny conditions and temperatures in the 60s.
