After a stretch of mild September weather, conditions are about to change across coastal BC as an atmospheric river arrives this weekend.
According to The Weather Network, a narrow band of Pacific moisture is moving down the coast from Alaska and northern BC.
The weather system is expected to stall over the central coast and northern Vancouver Island. This system, rated an AR3, could bring an entire month’s worth of rain in just a few days to communities like Bella Bella.
In the hardest-hit areas, rainfall totals are expected to exceed 100 millimetres by Sunday.
The north coast could see 50 to 70 millimetres, while northern Vancouver Island may get up to 50 millimetres.
Fortunately for those attending Rifflandia this weekend, Greater Victoria might avoid the worst of the system, with Environment Canada predicting between five and 10 millimetres of rain this weekend.
Saturday is expected to stay mostly dry with a mix of sun and clouds and a high near 18°C. Sunday has a 40 percent chance of showers.
While residents of Victoria may miss the worst of the rain, forecasters say rain boots will be necessary for much of coastal BC this weekend.
