After doing a loop-the-loop out in the Atlantic Ocean last week, Hurricane Jose is poised to impact coastal New England with heavy rain and some possible flooding, according to the National Weather Service’s Hurricane Center.
“While the center of Jose is currently forecast to remain offshore of the U.S. coast, the large cyclone is expected to cause some direct impacts in portions of New England,” the center said in an advisory late Tuesday morning. However, forecasters expect the effects to be limited to coastal areas because the storm’s recent eastward shift.
With Jose's latest tracks, areas further inland may see minimal impacts. However, southeastern New England could still see TS conditions.

A tropical storm warning is still in effect for the coast of Rhode Island and parts of southeastern Massachusetts, including Cape Cod. A flash flood watch is in effect for Cape Cod.
Officials say “minor to moderate” coastal flooding is possible from Delaware to New England, though it will be “limited in scope.” Scattered power outages and heavy downpours are also possible, according the NWS branch in Taunton. The Hurricane Center forecasts three to five inches of rain for Martha’s Vineyard, Nantucket, and Cape Cod through Wednesday. Total rain for the rest of New England is projected to be three inches or less.
Here are seven maps showing Jose’s predicted wind speeds, rainfall, path, and arrival.
This graphic shows the likelihood of sustained average wind speeds of at least 39 miles per hour:

This model shows when individual locations may expect the arrival of tropical-storm-force winds. According to the National Hurricane Center, preparations for the storm should ideally be completed by this time.
This map shows the areas potentially being affected by the sustained winds of tropical storm force (in orange) and hurricane force (in red), as well as the storm’s past track.
A tropical storm warning is issued when sustained winds of 39 to 73 mph or higher associated with a tropical cyclone are expected in 36 hours or less. Storm surge, coastal flooding, and/or river flooding is also possible.
According to the National Weather Service, a flash flood watch is issued when conditions are favorable for flash flooding. It doesn’t mean flashing flood is imminent, only that it is possible.
