Mariners are urged to take caution as Hurricane Jose causes high seas and potentially dangerous riptides off Cape Cod and Nantucket, the National Weather Service said.

A heavy surf and a risk of rip currents means that through Tuesday, “anyone thinking of being in the water along the South Coast, for sure, is putting their life in danger,” said William Babcock, a meteorologist at the National Weather Service.

Forecasters put out a small craft advisory at 6 p.m. Friday, urging small crafts to not go out until the danger from Jose has passed. As of 11 p.m. Saturday , waves between 4 and 7 feet high had been reported south of Martha’s Vineyard, although forecasters warn that individual waves could be twice that. The advisory is in place until 6 a.m. Monday, although it could be extended into the week, according to forecasters.


As of 11 p.m. Saturday, the storm was about 465 miles off the coast of North Carolina, according to the National Hurricane Center, with the center of the storm expected to pass 150 to 200 miles off of Nantucket on Tuesday or Wednesday, according to forecasters.

“We’re still tracking this storm, but nothing’s changed since last night,” Kevin Cadima, a meteorologist at the National Weather Service said Saturday. “Our tracking has an average error of 200 to 250 miles, so it could be a substantial event or it could go east and have relatively little impact. It all depends on how far north the storm gets before it changes direction.”

Cadima wouldn’t comment on what the potential effect of Jose might be, but as of Saturday, the storm was a Category 1 hurricane with potential wind gusts of up to 80 miles per hour, forecasters said.

Jose could also pummel affected areas with more than 6 inches of heavy rain, leading to beach erosion and possible flooding, according to the Massachusetts Emergency Management Agency.


The National Weather Service will continue to monitor the situation and hoped to have a better sense of Jose’s effect on New England by late Monday evening, Cadima said.

In spite of Jose’s impending arrival, the rest if the weekend is expected to be mild, according to the National Weather Service.

Sunday is expected to be about 72 degrees. A light fog is expected before 10 a.m. but will burn off as the afternoon becomes sunny. Eastward winds of 5 to 7 miles per hour are expected, forecasters wrote.

Monday will likely be similar to Sunday also with a high of 72 degrees but cloudy through the afternoon. There is a 20 percent chance of showers after 3 p.m., which could rise to about 40 percent in the evening, forecasters wrote.

On Tuesday the mercury is expected to drop slightly to about 70 degrees with a 70 percent chance of precipitation including thunderstorms after 10 a.m., forecasters said.

The Boston area could see tropical storm conditions, depending on Jose’s path Tuesday, officials said.
