Hurricane Gaston formed off the coast of Georgia on August 27, 2004. Gaston was originally classified as a tropical storm. However, upon reanalysis of storm data The National Hurricane Center reclassified Gaston as a category-1 hurricane. After moving inland over South Carolina, Gaston began to turn northeast and enter the Canadian Response Zone on August 31 as a tropical storm, moving into Canadian waters late in the day. Maximum winds in the Response Zone reached 83 km/h as the system tracked south of Nova Scotia and Newfoundland, eventually dissipating on September 2. Gaston completed the transition from its tropical to extratropical phase as it passed south of Sable Island, on the morning of September 1. Heavy rain north of Gaston just missed mainland Nova Scotia but fell at Sable Island which recorded 72 mm in four hours (35 mm in one hour). No significant impacts were reported from Canadian waters or territory. The CHC issued 20 Hurricane Information Statements.
