Hurricane Gaston is producing maximum sustained winds of 105 miles per hour and stronger gusts as it churns through the Atlantic Ocean, the U.S. National Hurricane Center said in an advisory.

The system, which is not threatening any land mass, was located about 600 miles east of Bermuda and moving toward the northwest at about 5 mph as of 11 a.m. EST, the Miami-based weather forecaster said on its website. It is expected to turn toward the north Monday.

The National Hurricane Center said Saturday evening the system had strengthened to a Category 1 hurricane with maximum sustained winds of 85 mph.

Some additional strengthening was possible during the next day or so, the National Hurricane Center said in its latest advisory.

There were no coastal watches or warnings in effect for the storm, the National Hurricane Center said.
