Hurricane Watch and Storm Surge Watch in effect for the Long Island and the southern New England Coasts, including Cape Cod MA.

As of Friday morning, Tropical Storm Henri is located about 780 miles south-southwest of Nantucket MA, moving to the northwest at 9 mph. Maximum sustained winds are 65 mph.

Henri is expected to turn to the north early today. By Sunday, Henri may be approaching the southern New England coast. This is a dangerous track for Cape Cod and coastal MA, as the most hazardous side of the storm will potentially impact these areas.

Tropical Storm force winds are possible on the southern New England Coastline starting Sunday morning. Cape Cod, RI and the MA coastline all have relatively high chances of experiencing destructive (greater than 60 mph) winds associated with Henri. There will likely be a 2-4 foot storm surge in Long Island Sound and a 3-5 foot storm surge in Narragansett Bay RI, Nantucket Sound, and Cape Cod Bay.

I would not travel to Long Island or the southern New England Coastline and especially not to Cape Cod this weekend. If you are already there camping in your RV, please follow the directions and guidance of your local emergency management officials. Personally, if I was visiting, I would leave if that is possible. Regardless, I would ensure I had full tank(s) of gas/diesel, full fresh water and propane, and empty gray and black tanks. Ensure you are out of danger of any storm surge. On Cape Cod and RI, the strongest winds will likely be from the east and southeast

Please monitor the National Hurricane Center forecasts, either directly from their website, through local TV stations, or reputable, established weather websites.
