Storm hitting Atlantic Canada 'very similar' to what struck B.C.: meteorologist

“It's a very similar storm,” Bob Robichaud, a senior Environment Canada meteorologist based in Nova Scotia, told CTVNews.ca in a phone interview. “It's the same type of atmospheric setup that would generate this type of rainfall.” He explained that this type of extreme rainfall event, like the one in B.C., occurs when a “very concentrated plume of moisture in the atmosphere that streams up from the tropics” becomes part of a storm.
