From September 26th through 28th, a fall season Nor’easter impacted greater Long Island and southern Connecticut. This severe weather event caused coastal flooding, strong winds, heavy rainfall, and power outages. Nor’easters are coastal low-pressure systems that form in the Atlantic Ocean and get their name from the strong northeasterly winds they bring when impacting the eastern coast. Although these events can happen at any time of the year, the peak and most intense activity typically occurs from January through March, which makes this event notable for how intense and early it was. In this radar composite you can see the early bands of the storm rotating counterclockwise.
The National Weather Service’s rainfall analysis shows Long Island received rainfall totals as high as 6.6 inches, with Suffolk County receiving more than Nassau County. Numerous areas on both the north and south shores of Long Island reported major coastal flooding, with several river gauges in Freeport, Lindenhurst, and Port Jefferson reporting major floods through their hydrographs. Both the Main and Southampton campuses of Stony Brook University were impacted by heavy amounts of rainfall.
The School of Marine, Atmospheric, and Sustainability Sciences Southampton Marine Sciences Center weathered the storm, as seen in these two time lapse videos. You can also see the cloud rotation moving from the left (east) to the right (west).
