Severe Weather Alert: Henri will bring damaging winds, heavy rain and flooding on Sunday

Pinpoint Weather Alerts

Henri remains a Category 1 Hurricane as of the latest update from the National Hurricane Center. The storm has sustained winds of 75mph and is moving northward and accelerating. This continues to point to a high impact situation for Southern New England with damaging winds, heavy rain and potentially significant storm surge flooding.

The storm is expected to continue to move toward the Rhode Island coast Sunday morning. In response, the Hurricane Warning has been expanded to include coastal RI in addition to Long Island and coastal CT and Tropical Storm Warnings for the rest of CT, RI and parts of Southeastern MA.

Storm Surge Warnings have also been issued across our region. A “Warning” means hurricane conditions and storm surge flooding is expected Sunday.

A Flood Watch has also been issued for all of RI and CT with the potential for 1-3″ of rain from Henri in our area, leading to localized street and poor drainage flooding along with the threat of stream and river flooding.


The latest info from our computer model guidance and the National Hurricane Center shows Henri making landfall between Montauk (eastern Long Island) to New Bedford….perhaps crossing right over Block Island and Charlestown. The impacts will be felt far outside where the storm makes landfall, however.

Overnight, expect increasing clouds with some showers/downpours possible toward dawn.

The winds will be picking up early Sunday as well with some gusts of 30-40mph near the coast at dawn. Temperatures overnight will remain warm…low to mid 70s.

HOUR BY HOUR: Conditions for the next 36 hours »

Conditions will deteriorate through the day on Sunday as Henri brings rounds of tropical downpours and strong, damaging winds. Some downpours are possible early Sunday morning.

While the chance is low, it’s possible there could be a quick spin-up of a tornado or waterspout.

The center of the storm will come ashore around mid-day 10am -2pm…that’s when the strongest of the winds and storm surge are expected. The closer to 2pm for a landfall the better….that’s about when low tide is and the storm surge will be less of an impact.

Henri will continue to move inland through the evening and the winds will weaken, but the heavy rain could continue, especially west of the track.


Please prepare now for the potential for wind damage and multi-day power outages, rainfall and storm surge flooding, along with significant beach erosion. We will also see large, dangerous waves and a high risk for rip currents at area beaches, starting as early as this evening.

WIND: Tropical storm force winds are likely with this storm with the potential for some gusts to near or over hurricane strength. The strongest winds in RI are expected at the coast, but power outages and wind damage are likely inland, too. The ground is pretty saturated as a result of the wet summer. In addition, trees are still fully-leaved, so trees could topple more easily with the strong winds.

RAIN: The heaviest rain will be along and just west of the center of Henri. Right now, CT and western MA are the favored areas for significant rainfall. However a shift in the track to the east could bring higher rainfall into RI and parts of SE MA, too.

STORM SURGE: We are concerned about significant flooding around high tide Sunday morning (~7-9 AM) and again on Sunday Evening (~7-9PM). Tides will already be astronomically high due to the full sturgeon moon and Henri will push additional water up the coast and bays. As mentioned before, the worst of the storm surge may coincide with low tide, which will be good. We’ll watch this closely.

Please check back with us for more updates as new data comes in through Sunday.
