Normal for this time of the year.....In addition to "Chinooks" (specifically, the wet coastal version) and "Pineapple Express," British Columbia's fall storms are also commonly referred to by meteorologists and the public as:
  • Atmospheric Rivers
  • Southeasters (referring to the strong, often damaging, wind events)
  • Bomb Cyclones (or "weather bombs," "bombogenesis," "explosive cyclogenesis"), which describes a low-pressure system that rapidly intensifies over a 24-hour period, bringing heavy rain and powerful winds.
  • Generic terms such as low-pressure systems or simply fall storms.

The term Pineapple Express is a colloquial name for a specific type of atmospheric river that originates near the Hawaiian Islands and transports a "river" of tropical moisture to the West Coast. Chinook winds have two meanings in North America; the original coastal BC term refers to the warm, wet winds from the ocean, while the more common inland usage (e.g., in Alberta) refers to a warm, dry foehn wind that descends the leeward side of the Rocky Mountains.
