Tropical Storm Warnings in the Northeast with Hurricane Jose

18 Sep 2017, 2:22 pm

Hurricane Jose is located well off the East Coast, but the storm will still be close enough to create some problems. Even with the cyclone staying well out to sea, tropical storm force winds, rough surf, dangerous rip currents and coastal flooding are likely to occur. The cyclone is located about 265 miles east-southeast of Cape Hatteras, NC and 490 miles south of Nantucket, MA. Hurricane-force winds extend outward up to 60 miles and will stay offshore, but tropical-storm-force winds extend out to 230 miles from the center of the storm, which may reach the coast. Maximum sustained winds are near 75 mph with higher gusts.

Tropical Storm Warnings continue along the coast from Watch Hill to Hull, Block Island, Martha’s Vineyard and Nantucket. Tropical Storm Watches remain in effect for Fenwick Island to Sandy Hook, Delaware Bay South and East Rockaway Inlet to Watch Hill. High Surf Advisories are also in affect throughout the Middle Atlantic and Northeast.

Swells generated by Jose are affecting Bermuda, the Bahamas, and much of the U.S. east coast. These swells are likely to cause dangerous surf and rip current conditions for the next several days in these areas.

Satellite images indicate that Jose is losing some tropical characteristics. The cloud pattern of the hurricane is asymmetric with its thunderstorm bands, which has been confined to areas north of the center. The NOAA and Air Force Hurricane Hunters have found that Jose is weaker with lower winds.

Jose should remain over warm Gulf Stream waters during the next 24 hours, but it will also be entering an environment of strong wind shear, so little change in strength is expected. Tuesday into Wednesday, the hurricane is forecast to cross into a progressively drier air mass. These unfavorable conditions should cause a slow weakening trend and lead to post-tropical transition, which is now expected to be complete by the end of the week.

The hurricane has been wobbling around with a general north motion. A ridge over the western Atlantic
should continue to steer Jose northward. For the rest of the week, a storm system currently over Central Canada is expected to cause Jose to turn eastward.

Jose is expected to produce total rain accumulations of 3 to 5 inches over eastern Long Island, Southeast Connecticut, South Rhode Island, and Southeast Massachusetts, including Martha’s Vineyard and Nantucket through Wednesday. Jose is also expected to produce total rain accumulations up to 2 inches along the mid-Atlantic coast, and from southeast New York to coastal Maine. This rainfall could cause isolated flooding.
