SITUATIONAL AWARENESS STATEMENT #5
DATE: January 4, 2018
TIME: 9:00 AM
SUBJECT: Coastal Flooding Concerns
Coastal Flooding Concerns
The National Weather Service (NWS) is forecasting moderate coastal flooding with a pockets of major coastal flooding along east and north facing shorelines south of Boston and on Nantucket. As of 9 AM, the surge had increased to around 1.9 feet in Boston and 1.8 feet in Nantucket. Waves height may build to around 15 feet off Cape Ann and Mass Bay by the time of the high tide (mid-day). Wind direction at the time of the high tide looks to be about 020 degrees or NNE along most of the eastern MA shoreline.
In addition, NWS is anticipating rather extensive inundation and some damage to very vulnerable structures and infrastructure along the immediate shore, such as decks, stairs, docks, parking lots, and the like. Some neighborhoods may become isolated and many shore roads may become impassable for a while and remain impassable long after the high tide due to slow drainage. The Plymouth County coast, and Cape Cod Bay shoreline from Sandwich to Dennis and perhaps even further east to Eastham, are areas of particular concern. Due to such high water levels and strong onshore winds, there is a potential for serious impacts to route 6A in Sandwich among other locations.
