Sept. 30 (UPI) — Humberto weakened to a Category 3 storm on Monday in the Atlantic, according to forecasters, who expected it to continue to lose strength over the next few days.

Humberto had maximum sustained winds of 115 mph, the National Hurricane Center said in its 11 p.m. AST update, a drop of 30 mph in the last 12 hours.

It was located about 265 miles southwest of Bermuda and was moving north-northwest at 14 mph, according to forecasters.

Hurricane-force winds extend outward up to 65 miles from the center of the storm, and tropical-force winds extend outward up to 200 miles.

No watches or warnings were in effect.

“On the forecast track, the center of Humberto will pass west and then north of Bermuda on Tuesday and Wednesday,” the NHC said.

Though the storm is expected to continue on its weakening trajectory, it is forecast to become a “strong extratropical system” in the next few days.

Swells generated by Humberto are likely to cause dangerous surf and life-threatening rip current conditions, affecting beaches of the northern Caribbean, Bahamas, Bermuda and much of the U.S. East Coast for the next few days.

Humberto is the eighth named storm of the Atlantic season and became the season’s third hurricane on Friday morning.

On Sunday, it was joined in the Atlantic by Tropical Storm Imelda.
