Bands of rain rotated around the periphery of a slow moving, but vigorous, low pressure system from the 12th through the 15th. Extremely heavy rainfall combined with rough seas and incoming astronomical high tides to produce localized coastal flooding along the coast of New Hampshire. In Portsmouth, New Hampshire, emergency crews dealt with drainage issues created by shifting tides.
