Tropical Storm Hermine's Expected Impact on Connecticut for Sunday, Labor Day: Latest Update

Tropical Storm Hermine is slowly moving up the East Coast and Connecticut should begin to see some of the effects of the powerful storm later on Sunday and Labor Day. (For continued updates on the storm, including news on power outages and road closures, sign up for Patch news alerts here.)

The Connecticut coastline from Greenwich to New London will see the greatest impacts from this storm. A Tropical Storm Warning has been issued for areas along the immediate coast.

Interior sections of Fairfield, New Haven, Middlesex, New London, along with Hartford and Tolland counties will see less effects from Hermine and are under a Hazardous Weather Outlook.

Hermine’s impact on Connecticut isn’t going to be a major rainstorm. The immediate coast may see up to an inch of rain total, and areas inland may see a half inch of rain, according to the current projections from the National Weather Service.

The real concern in Connecticut, especially at the coast, is the wind and storm surge which may result in moderate to severe coastal flooding later on Sunday. On the coast, winds will gust 20 to 30 mph and possibly up to 50 mph, the weather service states.

The storm surge at the coast may be 2-4 feet above ground beginning early Sunday afternoon, the weather service states. Damage to buildings near the coast is possible, the weather service states. There could be damage to marinas, docks, boardwalks, and piers too.

In interior sections, some showers are possible and gusty winds at times but the major effects are more likely at the immediate coast.

Governor Dannel P. Malloy is continuing to caution shoreline residents about possible flooding from Tropical Storm Hermine, especially those in low-lying, flood prone areas as tropical storm warnings have been issued for the immediate Connecticut coast.

In addition, all Connecticut state park campgrounds will close at noon on Sunday, Sept. 4 due to the anticipated conditions.

The Governor will also partially activate the state Emergency Operations Center in Hartford beginning at 6 p.m. on Sunday.

"After assessing the current forecast with emergency management officials, I have decided to partially activate the state emergency operations center on Sunday evening to monitor conditions across the state. This will also allow us to better coordinate any assistance to our municipalities that may be necessary," Governor Malloy said in a news release. "If you live in a low-lying, flood prone area, please stay alert to changing weather conditions, especially during high tide cycles over the next few days."

Hermine continues to move into the Atlantic off the Mid Atlantic Coast. The storm will then turn north and regain strength on Sunday and stall off the coast Sunday night into Monday before resuming a slow northeast track southeast of Long Island Tuesday into Wednesday, the National Weather Service states.
