The fierce weekend nor'easter that pounded Long Island may be history, but that doesn't mean we're out of the woods yet.
The National Weather Service has issued a coastal flood advisory - in effect from 10 a.m. to 2 p.m. Monday, then again from 7 p.m. Monday until 2 a.m. Tuesday - due to "increased tidal piling" and tides that, in many places, will be at least 2 feet above normal, officials said.
"A combination of strong northeast flow and a persistent strong southeasterly swell will result in increasing tidal piling along the coasts," the weather service said in the advisory.
Forecasters predict steady winds of from 20 to 22 mph in the area Monday with rainfall of a quarter-inch. Overcast skies and light rains are likely into Tuesday before skies clear Tuesday night and sunshine returns Wednesday.
And current conditions continued to make life difficult for Long Islanders on Monday.
While anticipated major morning rush-hour delays on the Long Island Rail Road were averted when emergency crews were able to pump water out of a flooded westbound East River tunnel, Long Island roads remained slick and treacherous, with flooding in some areas. There were significant delays reported at LaGuardia Airport, with smaller delays expected throughout the day at other area airports.
The Long Island Power Authority reported more than 66,000 power outages at 9 a.m. Monday - including more than 3,500 customers still without power in Oceanside; more than 3,000 without power in Island Park and Copiague; more than 2,000 without power in Baldwin, Massapequa, Rockaway Beach, Far Rockaway and West Babylon; and more than 1,000 without power in Atlantic Beach, Bay Shore, Bellmore, East Massapequa, Lindenhurst, Merrick, Seaford, South Valley Stream, Valley Stream, Wantagh, West Islip and Woodmere.
A LIPA spokeswoman said more than 1,500 emergency workers were out in the field trying to restore power.
It was unclear Monday how current weather conditions would affect the ability of those workers to restore outages, and if the wet, soggy ground and gusting winds would lead to additional downed trees, utility poles and wires, or if the crews would be able to make decent progress despite ongoing challenging conditions.
