Saturday Storm Summary with a peek into November

As promised by meteorologists a 994 mb extratropical cyclone slammed into the southern tip of Vancouver Island, creating strong winds and high waves causing numerous ferry cancellations with an incident being reported by the Queen of Nanaimo.  

Details about the incident, but in summary:  

  • 10:45 am Saturday morning the Queen of Nanaimo began to back out of it's berth on Mayne Island
  • High winds knocked the ferry out of position and the 22 crew on board quickly followed emergency procedures by dropping anchor to prevent further damage
  • Divers have found some damage to sensitive propeller equipment today, so the ferry will remain out of service indefinitely
  • 2 passengers were on board. Yes, 2. Not a typo. 

Vancouver was spared the strong winds, but a high amount of convergence at the southern end of Georgia Strait and Juan de Fuca led to high amounts of rainfall during the day for the Lower Mainland and North Shore mountains. Lower freezing levels brought a lot of fresh powder above 800 meters above sea level.

Summary by Environment Canada (rain recorded past 24 hours):

  • Ucluelet 96.4 mm
  • Tofino 74.4 mm
  • Campbell River 38.6 mm 
  • Courtenay 59.2 mm
  • Nanaimo 40.6 mm
  • North Vancouver 45.4 mm


At the height of the storm over 100,000 customers lost power in Washington State along with a rare 520 Bridge closure. You can see why with wind gusts approaching 100 km/hr.

A look ahead:

  **Widespread frost expected tonight especially away from the water**

Higher levels of the atmosphere are showing a NW flow, but this flow will switch to a more westerly, moister flow with scattered showers Monday evening and overnight as a week front pushed on through the region.

A stronger weather system and surface low is on tap for Wednesday evening, but uncertainties on the exact track are still in question. I'll keep you updated once models get a handle on the system a little better.

Another system is then on track for the weekend! Have that umbrella handy :)
