We’re starting to see the impacts of our nor’easter across Long Island, with beach erosion and coastal flooding already occurring in some shoreline communities this morning. Conditions will gradually deteriorate through the day as winds increase and rain begins to move in. The biggest impacts from this storm are expected over the weekend, when we’ll be tracking heavy rain, strong wind gusts, beach erosion and coastal flooding.
For today, expect mostly cloudy skies with winds becoming increasingly gusty. Gusts of 30 to 35 mph are possible, with high temperatures generally in the 60s. Coastal flooding will be a concern around the morning high tide, with another round possible during the evening high tide, generally between 6 p.m. and 10 p.m. Rain showers will become more widespread during the afternoon and evening as the nor’easter draws closer.
Conditions will turn increasingly stormy Friday night. Periods of rain are expected, with some moderate to heavy rainfall possible at times.
