Tropical Storm Henri will affect the US; much more uncertain

“The biggest point here is it’s still too early to know exactly how close Henri’s center is to the New England coast,” the National Hurricane Center said. (NHC) said.

Even if Henri stays ashore, swellings from the storm could cause life -threatening high surf and rip waves.

However, the NHC’s official forecast has landfall as a possibility for New England, from Connecticut to Maine.

“It should be noted that as Henri gains latitude and moves closer to New England, the wind field is expected to expand,” NHC said. in an update. “Therefore, users are reminded not to focus on the exact forecast points because the effects will extend far into the center.”

The NHC said watches and warnings for locations inside the cone will likely be needed over the weekend, and could be issued early tomorrow.

It doesn’t help that weather forecasting models seem to be all over the place when it comes to Henri’s predicted track.

The American morning forecast model is approaching the center of the coastal storm.  This will allow the effects to be wider from eastern Long Island, NY, to Maine.

Massachusetts, which has the potential to take a direct hit, can expect many potential hazards such as harmful winds, hurricanes and heavy rain.

“Keep in mind that astronomy will be high this weekend along both coasts,” the National Weather Service (NWS) said. in Boston.

The timing of the high-tide is important because the rising phase of the moon will be higher than normal, so any storm collapse at its peak could trigger enhanced coastal flooding.

“The track will tell us which coast is most at risk (east coast vs. south coast) or if both will play out,” the Boston NWS said.

The start of tropical-storm-strong winds for the Massachusetts coast is expected Sunday morning, so the NWS urges that all preparations be made at that point.

Although models may differ on what exactly the impact will come from Henri, it’s always better to be prepared in case storms hit.

Henri is likely to deliver these effects

“In general, in tropical storms the biggest impact comes from pouring rain,” said Margaret Curtis, a NWS meteorologist in Portland, Maine.

Thanks to the remnants of Tropical Storm Fred, most of New England will receive heavy rainfall today. There will also be additional rain opportunities in most of the Northeast this weekend, so flooding will be a concern even before henri has the potential to reach the area. But Curtis explained that there are other concerns as well.

“For the coast, high surf and pounding can create flooding and coastal erosion,” Curtis said.

And the high surf, as well as the rip waves, aren’t just limited to the Northeast. Coastal communities from North Carolina all the way through Atlantic Canada can experience “deadly surf and rip waves,” according to the NHC.

Extreme weather balloon launches are expected to occur along most of the East Coast. These additional launches provide too much insight into what the environment can do to influence the track of Henri’s prophecy.

“Hunter planes sampling the atmosphere around a storm are likely to play a bigger role than over -launching in gaining accuracy and confidence in the upcoming model output,” said Chad Myers, CNN meteorologist. .

“It’s too early to determine what the storm will do at this time, but a direct collapse as a hurricane and then the center of the ground stop producing severe flooding seems to be the worst situation in some current model outputs. “
