Long Island weather alerts
UPDATE 2:30 P.M.: Storm warning in effect for Long Island Sound East of New Haven, Connecticut and Port Jefferson to the mouth of the Connecticut River until 12 p.m. Sunday.

WHAT YOU NEED TO KNOW

The worst of the nor'easter will occur Saturday night into Sunday morning. Expect drenching rain, damaging wind gusts and moderate to major coastal flooding during high tide. Weather conditions will continue to deteriorate as the storm moves closer to Long Island.
Wind gusts over 60 mph was reported over parts of Long Island on Saturday morning. Gusts up to 60 MPH isn't out of the question as the center of the storm moves closer to the area. Scattered power outages and downed trees will continue to be a threat through the duration of this storm due to the supersaturated ground and weighted branches from heavy rainfall.
Coastal flooding is one of the biggest concerns for Saturday night, especially around high tide. Water could cover coastal and low-lying roads, making some areas difficult or even impassable to travel through. Never attempt to drive through a flooded roadway.
Rainfall totals over 2" was reported over parts of the area since Friday with an additional 2" to 3" of rainfall possible through Monday. Street flooding and highway flooding will continue to be a concern with any heavy rainfall.
Sunday starts gusty with torrential downpours and another round of coastal flooding during the early morning high tide. Rain will gradually become scattered during the afternoon, with wind gusts near 35 to 45 mph. Coastal communities will need to remain vigilant through Sunday evening as another high tide brings an additional flooding concern.
The storm will slowly pull away on Monday afternoon, with leftover showers and breezy conditions. Weather conditions will really improve on Tuesday through the end of the week, with plenty of sunshine and milder temperatures in the 70s.
