Tropical Storm Hermine developed on August 27, 2004 south of Bermuda. Hermine intensified into a tropical storm carrying maximum sustained wind reaching 94 km/h. While entering the Canadian Response Zone on August 31, Tropical Storm Hermine contained winds reaching 83 km/h. A weak interaction with Tropical Storm Gaston caused Hermine to weaken as it tracked towards Cape Cod, following which, it became extratropical. The remnant low centre tracked up the Bay of Fundy on August 31, making landfall in New Brunswick, bringing heavy rain to portions of southern New Brunswick which received between 40 and 55 mm. Minor basement flooding and street closures were reported from Moncton, New Brunswick. The CHC issued 7 Hurricane Information Statements.
