An atmospheric river bringing warm air and moisture all the way from Hawaii is to blame for Monday’s record-breaking rainfall in Greater Victoria, according to Environment Canada.
The Malahat received the worst of the rain on Monday, with the weather agency recording 88 millimetres, enough to set a new record for precipitation for Nov. 15. Victoria International Airport and Gonzales Point also set new records for the date, with 79 and 72 millimetres recorded, respectively.
Meterorologist Bobby Sekhon said as bad as the storm was on Monday morning, it is important to note the rain started on Saturday and continued nearly non-stop, pushing the total rainfall for the region higher.
Combining those three days the Malahat received 188 mm of rain, the airport 126 mm and Gonzales Point 120 mm.
“Certainly there were a lot of records set, especially in the Fraser Valley where the precipitation was the most heavily concentrated,” Sekhon said. “It was certainly a heavy precipitation event.”
Atmospheric rivers are a weather phenomenon the Island can expect to deal with most falls and winters, but there have already been several this year, making September and October wetter and more active from a weather perspective.
