![]() ![]() These additional launches supply extra insight into what the atmosphere may be doing to influence Henri’s forecast track. ![]() NdPbRtlJNA- National Hurricane Center August 19, 2021Įxtra weather balloon launches are expected to take place along much of the East Coast. The storm is expected to be near southern New England on Sunday and Monday, and interests there should monitor its progress. Here are the 11 am AST Key Messages on Tropical Storm #Henri. ![]() Coastal communities from North Carolina up through Atlantic Canada could experience “life-threatening surf and rip currents,” according to the NHC. “For the coast, high surf and pounding can create coastal flooding and erosion,” said Curtis.Īnd high surf, as well as rip currents, won’t just be limited to the Northeast. But Curtis explains there are other concerns as well. There are also additional rain chances in much of the Northeast this weekend, so flooding will be a concern even before Henri potentially hits the area. Thanks to the remnants of Tropical Storm Fred, much of New England will be receiving heavy rainfall today. “Generally, with tropical storms the biggest impact is from flooding rains,” said Margaret Curtis, a meteorologist with the NWS in Portland, Maine. The onset of tropical-storm-force winds for coastal Massachusetts is expected Sunday morning, so the NWS urges that all preparations must be done by that point.Įven though the models may vary on what the exact impacts will be from Henri, it is always better to be prepared in case the storms hits. “Track will ultimately tell us which coastline is most at risk (east coast vs south coast) or if both will be in play,” the Boston NWS said. High-tide timing is important because the moon phase tides will already be higher than normal, so any storm surge on top of that could trigger enhanced coastal flooding. “Keep in mind tides will be astronomically high this weekend along both coasts,” says the National Weather Service (NWS) in Boston. Massachusetts, which has the potential to take a direct hit, can expect multiple potential hazards such as damaging winds, storm surge and heavy rain. This would allow impacts to be more widespread from eastern Long Island, NY, up through Maine. The morning American forecast model brings the center of the storm closer to shore. ![]()
