The NWS has issued the following warnings/watches for our area in reaction to the impending nor'easter:

A flood watch is in effect from 6 a.m. Friday to 6 a.m. Saturday for all of Long Island.

A coastal flood warning is in effect from 6 a.m. to 11 a.m. Friday for southern Nassau County.

A high wind watch is in effect from 7 a.m. Friday to 6 a.m. Saturday for Nassau and western Suffolk County.

A high wind warning is in effect from 7 a.m. Friday to 6 a.m. Saturday for eastern Suffolk. ​

The NWS has released the following statement regarding the nor'easter and its expected impact upon the Long Island region, noting that residents should expect and prepare for power outages; in addition, they advised caution when traveling – especially in low-lying coastal areas, where flooding is most likely – and urged residents to do so only when absolutely necessary.

"Damaging winds will blow down trees and power lines. Widespread power outages are expected. Travel will be difficult, especially for high profile vehicles,” the NWS said. "There is potential for several tidal cycles of widespread flooding of vulnerable areas near the waterfront and shoreline. Two to three feet of inundation above ground level in low lying, vulnerable areas is possible. This would result in numerous road closures and cause widespread flooding of low-lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront. Vehicles parked in vulnerable areas near the waterfront would become flooded."
