This morning, Long Islanders woke up to incredible flooding - last night's torrential downpour drenched the Island, damaging countless homes and cars, making many local roadways impassable, and causing at least one fatal accident. At Islip's MacArthur Airport, rainfall totals exceeded a foot - the official reading from the National Weather Service was a whopping 13.27 inches. Islip's rainfall was the highest recorded total for the day, although many coastal towns in both Nassau and Suffolk reported rainfall totals of over half a foot.
The heavy flooding prompted the Town of Islip to declare a state of emergency, and Governor Cuomo to dispatch emergency recovery responders to assist with the clean up and recovery post-storm. This morning, there were closures on eleven major roadways on Long Island, including the Long Island Expressway, Northern State Parkway, Sunrise Highway, and the Wantagh State Parkway. Although the rain has stopped, and roadways are once again becoming drivable, there is still major flooding across Long Island, and Islip, as well as other hard-hit areas, will likely continue to recover from today's storm for days to come.
