Gaston weakens to post tropical storm: NHC

(Reuters) - Gaston weakened to a post-tropical storm and was moving away from the Western Azores in the Atlantic Ocean, the National Hurricane Center said on Saturday. Gaston, formerly a hurricane, was located about 120 miles (190 km) north of Lajes Air Base in the Azores, with maximum sustained winds of 35 miles per hour (55 kph), the Miami-based weather forecaster added. The weather service said in an earlier advisory that the Gaston was a depression, which is a system with winds of 38 mph (62 kmh) or less. The post tropical designation describes a system that no longer is a tropical cyclone. (Reporting by Brendan O'Brien in Milwaukee; Editing by Kim Coghill)
