MIAMI (AP) — Tropical Storm Melissa formed in the far eastern Atlantic early Saturday, becoming the 13th named storm of the hurricane season, but posed no immediate threat to land, forecasters said.

At 5 a.m. EDT, Melissa had maximum sustained winds near 40 mph, and slight strengthening was forecast during the next 24 hours, according to the National Hurricane Center.

The center of the storm was located about 260 miles west-southwest of the Cape Verde Islands. Melissa was moving west near 3 mph and was expected to gradually turn west-northwest.

Meanwhile, Tropical Storm Karen continued weakening in the open Atlantic, and the remnants of Hurricane Lorenzo were bringing rain to central Mexico. Lorenzo hit Mexico's Gulf coast early Friday as a hurricane but quickly weakened to a tropical depression as it charged inland.
