Coastal Flood Warning Issued for Cape Cod

A coastal flood warning is in effect for Plymouth, Barnstable, Dukes, and Nantucket counties from 1 a.m. to 7 a.m. on Monday. The National Weather Service forecasts two to three feet of inundation above ground level in low-lying areas adjacent to shorelines and tidal waterways.

Several roads near harbors, including Nantucket Harbor and Edgartown Harbor, are expected to become impassable due to 1 to 2 feet of water. This flooding may impact access to ferry terminals and coastal routes. Drivers are advised to take necessary precautions to protect property and avoid driving through water of unknown depth.

The weather service defines advisories, watches, and warnings, with a flood warning indicating that flooding is imminent or already occurring. They urge individuals in flood-prone areas to move to high ground and follow evacuation orders if issued.

Safety guidelines emphasize seeking higher ground, disconnecting utilities if time permits, and avoiding basements or submerged areas due to electrical hazards. The service strongly advises against walking through floodwaters, noting that even six inches of fast-moving water can cause a person to be swept away. Vehicles can also be carried away by as little as 12 inches of flowing water.
