Residents are reminded to always dial 9-1-1 for emergencies. Īdditionally, residents dependent on critical life safety items, such as suctions or ventilators, and who may need assistance using these items during the storm are encouraged to identify themselves by contacting the Acton Fire Department at 97.

Residents are encouraged to sign up for emergency alerts from the town at /subscribe. If it becomes necessary to issue a dam safety watch or warning, the town will issue emergency alerts through the reverse 9-1-1 system. The town took measurements today to establish a baseline water level and is prepared to implement the Emergency Action Plan should water levels become dangerous. Town officials are closely monitoring the water levels and condition of the River Street dam. Town officials are receiving briefings as the situation is updated, and are staying current on storm tracks and forecasts to ensure staffing is in place to deal with any emergency that arises. However, the exact path and strength of the storm when it gets closer to New England are still uncertain and residents are urged to stay alert and monitor the local forecast. There is a Hurricane Watch in effect for parts of Rhode Island, and a Storm Surge Watch for parts of the South Shore of Massachusetts. These swells could cause life-threatening surf and rip currents. Swells from Henri are expected to reach the East Coast on Friday and continue through the weekend. There is a potential for tropical storm or lower-end hurricane force winds along with rough seas.

Henri is forecast to intensify into a hurricane on Friday with additional strengthening predicted to occur this weekend. The center of Henri is expected to remain offshore of the East Coast during the next couple of days, but is forecast to track near Cape Cod and the Islands or just offshore Sunday into Monday. Friday, Tropical Storm Henri is moving west-northwest over the western Atlantic and is about 770 miles south-southwest of Nantucket. It is recommended that residents stay alert and prepare to take the necessary safety precautions as Tropical Storm Henri is expected to track toward in New England in the coming days.Īccording to the National Hurricane Center, as of 11:30 a.m. The end result is a reasonably confident forecast that Henri will make landfall in New England this weekend. There’s still a chance that the storm could turn out to sea-remember, the cone of uncertainty is the historical margin of error in a forecast’s track-but the most likely outcome is a landfall in this heavily populated part of the country.įollow the National Hurricane Center’s website frequently over the next couple of days for the latest information on the storm and its effects in the region.Tropical Storm Henri Safety Tips and Preparations Meteorologists gave the models another leg-up by sending up a NOAA jet to sample the atmosphere around the storm, providing extra data for the models to work with. These models do a better job when they start out with better and more frequent data. Sending up extra weather balloons helps set the initial conditions of the weather models. When you plot all of this balloon data on the same map, it paints a pretty good picture of winds, pressure, and moisture through each layer of the atmosphere. These weather balloons tell us temperature, moisture, wind, and pressure data throughout the atmosphere. Much of that data comes from twice-daily weather balloon launches around the world. The models combine all of this data to simulate what the atmosphere will do in the coming days. They use formulas to simulate the atmosphere and different aspects of Earth’s surface, climatological data as a point of reference for past weather, and observations from ground stations, satellites, and radars to tell them what the atmosphere is doing right now. Weather models ingest data from lots of different sources.
