An area of low pressure intensified as it entered interior New England on January sixteenth with a 991mb surface low being observed. This produced storm force easterly wind gusts over the outer waters of the Gulf of Maine and 16 foot nearshore waves with a period of 8 seconds. These large waves and storm surge coincided at the time of high tide leading to coastal flooding on the New Hampshire Seashore.
