Today's Weather Trivia

30 August

2004: The remnants of tropical storms Gaston and Hermine merged over the Gulf of Maine and dumped 30 to 50 mm of rain over parts of New Brunswick. Two hours earlier, at high tide, a thunderstorm had dropped 26 mm of rain on Moncton, causing local flooding. With water reaching the headlights of cars and over the wheels of pick-up trucks, authorities closed the causeway and towed away 9 vehicles.
