Hurricane Teddy underwent extra-tropical transition to a strong 951 mb storm well off shore in the Gulf of Maine before moving north north towards Halifax, Nova Scotia. This powerful cyclone coincided with astronomically high tides bringing a second day of minor coastal flooding to the New Hampshire Seacoast. Although winds were offshore, large, long period swell entered the Gulf of Maine leading to splash-over and minor coastal flooding to coastal New Hampshire.
