What is a dancing storm? Good question. The Fujiwara effect “dancing storms” refers to the interaction between two cyclonic vortices. When two low-pressure systems near each other, they begin to orbit one another around a mid-point separating the two systems. The effect gets its nickname from the interaction of two systems appearing to “dance” around one another. Read more here.
WINDY DAY SATURDAY ALONG THE HAIDA GWAII ARCHIPELAGO
Southeasterly winds will pick-up along the channel separating the islands and the Mainland, Saturday. The most powerful wind & waves will remain off-shore. Still, gusty winds & rainfall along Vancouver Island and the Archipelago will lead to a lousy day. Wind gusts between 60-90km/h are likely.
WET ALONG THE COAST WITH SNOW IN THE MOUNTAINS
An unsettled couple of days across the Lower Mainland & Vancouver Island. 25-35mm of rainfall is expected across Vancouver & Victoria through Friday & Saturday. This will be a beneficial rainfall across the region, where its been an unusually-dry start to spring. Unfortunately, the rainfall isn’t expected to penetrate far enough into the interior to bring any relief to the dry conditions.
A more prolonged and significant rainfall is expected along Western sections of Vancouver Island. 40-70mm of rainfall is expected by the end of the day Saturday. The mountain peaks along the coast will see heavy snow – mixing or light accumulation is possible along sections of Highway 19.
