British Columbians should brace for a bomb cyclone bringing windy weather and heavy rains this week.

Environment Canada has issued a weather statement for much of the province, forecasting “very windy conditions” beginning Tuesday night and into Wednesday morning.

The “significant” fall storm will see winds increase along coastal areas throughout Tuesday afternoon, with winds hitting peak speeds overnight.

“Strong winds are likely to continue on Wednesday morning but should ease later in the day,” reads the statement.

Heavy rains are also expected in some areas during the storm, but winds remain the “primary concern.” Power outages, ferry cancellations, and damages due to downed trees are also possible.

The strong winds are the result of what’s called a bomb cyclone, according to the Weather Network. Also referred to as bombogenesis, a bomb cyclone describes a rapid drop in atmospheric pressure at the centre of a storm system. If the pressure at the eye of the storm drops quickly enough — roughly 24 millibars over the course of 24 hours — it is called a bomb cyclone.

The bomb cyclone responsible for this week’s winds will remain offshore. However, B.C.’s coast and mainland will still see intense wind gusts as a result. Weather analysts also suggest this week’s storm could be similar to a storm that hit Metro Vancouver in the fall of 2021; that storm introduced Vancouver to “Barge Chilling Beach.”
