How many coastal/sea level locations have gotten 30"+ from a single event? The only official locations I can think of are Cape May 34" in Feb 1899, PHL in Jan 1996 and JFK in Jan 2016!
I think Cape Cod got 30"+ in Jan 2005, but I dont know if that was an official measuring location (meaning airport or park lol.)
Come to think of it, the Brookhaven NWS office may have gotten 30" in Feb 2013......
