The historic nor’easter of 13-14 March 2010 By Richard H. Grumm National Weather Service 1. INTRODUCTION Gloria September 1985 (2.0m), Hurricane Donna September 1960 (1.73m), and the An historic nor’easter affected the East Coast of nor’easter of 12-13 December 1992 (1.75m). A the United States on 13-14 March 2010. The total of 17 tropical storms produced strong storm storm will be remembered for heavy rainfall surges. The list of extratropical cyclones (Fig. 1), flooding, strong winds, and the coastal includes many memorable East Coast Winter surge 1. Hurricane force wind gusts were Storms (ECWS) and famous nor’easters reported at Kennedy International Airport including the 31 October 1991 (1.40m), 13 (KJFK) around 0000 UTC 14 March 2010 when March 1993 “Superstorm” (1.46m), and the 7-8 wind gusts reach 64KTS (74 mph).

The strong winds produced the 14-15 November 1995 nor’easter (1.24). widespread power outages, downed trees, and Storm surges and coastal flooding are often produced coastal flooding due to a strong storm overlooked but important aspect nor’easters. The surge. storm of 13-14 March produced a surge of 1.28 m. This storm has been compared to several past storms. The nor’easters of 12-13 December 1992 As with many nor’easters, this storm produced and 07-08 January 1996 storms both produced high winds. The highest gusts were on Long strong storm surges along the East Coast. Unlike Island including KJFK (75 mph) and Breezy this storm, these storms produced areas of heavy Points (66 mph).
