Active Weather Alerts
Coastal Flood Watch
Issued: 7:48 PM Oct. 10, 2025 – National Weather Service
...COASTAL FLOOD WATCH REMAINS IN EFFECT FROM SUNDAY MORNING THROUGH LATE MONDAY NIGHT... * WHAT...One to two feet of inundation above ground level possible in low-lying areas near shorelines and tidal waterways (3.7 to 12.9 feet Mean Lower Low Water). * WHERE...Portions of eastern, northeastern and southeastern Massachusetts and northern and southern Rhode Island. * WHEN...From Sunday morning through late Monday night. * IMPACTS...Roads remain passable. Shallow pockets of flooding less than one foot deep affect more vulnerable coastal roads along the North Shore from Salem and Gloucester to Newburyport. Rough surf will likely cause some splashover onto coastal roads around the time of high tide. Roads remain passable. Low lying areas and roads near Nantucket Harbor, including Easy Street, may experience pockets of shallow flooding less than one foot deep. Minor coastal flooding occurs along the most vulnerable shoreline locales in Newport, Portsmouth and Middletown. This includes flooding at parking lots near beaches in Newport, and a portion of Hazard Road. Minor coastal flooding also occurs on several streets in the Common Fence Point area. PRECAUTIONARY/PREPAREDNESS ACTIONS... If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. && && Time of high total tides are approximate to the nearest hour.
