Canadian Hurricane Centre: history

Creation and evolution of the CHC

  • September 25-28, 1985 - Hurricane Gloria affected the Maritime provinces. Canadians had to rely largely on U.S. forecasts concerning this intense storm. When the storm's effects on Canada were much less than predicted, there was considerable confusion in the media and the general public. This eventually lead to the creation of the CHC.
  • 1986 - A study on tropical cyclones in Canada was commissioned to determine the need for a Canadian hurricane centre. The study, “30-year Climatology of Tropical Cyclones in Atlantic Canada,”was published by Barks and Richards.
  • August 31, 1987 - Environment Canada established hurricane centres on each coast: at the then Maritimes Weather Centre (Bedford, N.S.), and at the then Pacific Weather Centre (Vancouver, B.C.).
  • 2000 - The Canadian Hurricane Centre was established in Dartmouth, N.S., to serve all of Canada.
