    1. No, heavy rain is not as intense. And they They will have a Canadian rating system in place by Jan 2022. The amount of rain and the time it falls determines what class of atmospheric river it will be. Compare it to a very windy day, and a tornado, they have different classes of tornados too. A heavy rain will be classes a “0” . Whereas, 50 mm falling in 1 hour will be classed more as a threat. Google the atmospheric river, and get a scientific explanation. I

    2. @Shaarinya perhaps visit Merrit, or Abbotsford, and tell me otherwise, go back to your comic books, thousands of farm animals died in such intense rain that areas were flooded in under an hour. Do your homework. It is hysteria when your home floods in under half an hour and you can’t load up all your dogs and wedding photos quickly enough.

  1. An atmospheric river is a narrow corridor or filament of concentrated moisture in the atmosphere. Other names for this phenomenon are tropical plume, tropical connection, moisture plume, water vapor surge, and cloud band. Atmospheric rivers consist of narrow bands of enhanced water vapor transport, typically along the boundaries between large areas of divergent surface air flow, including some frontal zones in association with extratropical cyclones that form over the oceans. Pineapple Express storms are the most commonly represented and recognized type of atmospheric rivers; they are given the name due to the warm water vapor plumes originating over the Hawaiian tropics that follow various paths towards western North America, arriving at latitudes from California and the Pacific Northwest to British Columbia and even southeast Alaska
