FLOOD WARNING
Issue Date: 319 AM EDT Sun Sep 27 2026
COASTAL FLOOD WARNING REMAINS IN EFFECT UNTIL 8 PM EDT THIS EVENING
HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT THIS EVENING
WHAT
For the Coastal Flood Warning, up to one foot of inundation above ground level in low-lying areas near shorelines and tidal waterways (3.9 to 12.6 feet Mean Lower Low Water). For the High Surf Advisory, large breaking waves of 6 to 15 feet in the surf zone. WHERE
Eastern Essex MA, Suffolk MA, Eastern Norfolk MA, Eastern Plymouth MA, Barnstable MA, Dukes MA and Nantucket MA Counties. WHEN
Until 8 PM EDT Sunday. IMPACTS
Strong northeast winds with large waves will result in minor coastal flooding with pockets of moderate coastal flooding over multiple high tide cycles from late today through the weekend. The water also may struggle to vacate the area after the high tides given persistent strong northeast winds. The greatest risk for coastal flooding appears to be setting up south of Boston and onto the Cape and Islands. In addition
the long duration of northeast winds coupled with large waves over multiple high tide cycles will result in areas of severe beach erosion for a prolonged period.
PRECAUTIONARY/PREPAREDNESS ACTIONS
Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. && && Time of high total tides are approximate to the nearest hour.

FLOOD WATCH
Issue Date: 248 AM EDT Sun Sep 27 2026
FLOOD WATCH REMAINS IN EFFECT THROUGH LATE MONDAY NIGHT
WHAT
Flooding caused by excessive rainfall continues to be possible. WHERE
Portions of Massachusetts, including the following areas, Barnstable MA, Central Middlesex MA, Dukes MA, Eastern Essex MA, Eastern Norfolk MA, Eastern Plymouth MA, Nantucket MA, Northern Bristol MA, Northern Middlesex MA, Northern Worcester MA, Southeast Middlesex MA, Southern Bristol MA, Southern Plymouth MA, Southern Worcester MA, Suffolk MA, Western Essex MA, Western Norfolk MA and Western Plymouth MA and Rhode Island, including the following areas, Block Island RI, Bristol RI, Eastern Kent RI, Newport RI, Northwest Providence RI, Southeast Providence RI, Washington RI and Western Kent RI. WHEN
Through late Monday night. IMPACTS
Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. ADDITIONAL DETAILS
- Periods of rain will continue across the region right through Monday. Storm total rainfall amount of 2-4 inches are expected, but localized 5-7 inches amounts are possible. If these higher amounts are realized
the potential for both urban and small river/stream flooding would increase. This is particularly true if these localized higher amounts occur over a vulnerable urban center. - Http://www.weather.gov/safety/flood
PRECAUTIONARY/PREPAREDNESS ACTIONS
You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. &&
