Sept. 25 (UPI) -- Hurricane Lee is gradually strengthening while moving westward, the National Hurricane Center said Tuesday.
In its 11 a.m. advisory, the NHC said Lee had maximum sustained winds of 105 mph -- and was about 675 miles east of Bermuda and 1,620 miles west-southwest of the Azores. It was moving at 10 mph.
Forecasters note that Lee is a small tropical cyclone, and hurricane force winds only extend 15 miles from the center.
"The hurricane is expected to turn northwestward on Wednesday and northward on Thursday," the NHC said. "Lee could strengthen a little more before weakening likely begins on Thursday."
No coastal watches or warnings are in effect.
Lee became the 11th named storm of the Atlantic Hurricane season on Sept. 16 but dropped into a depression, and then a low. It became a hurricane for the first time Sunday, and the eye has since then become more defined, the NHC said.
