The advancing system in the west has cut power to thousands in BC with it’s fierce winds, heading into AB and SK where warnings and statements are widespread. The possibility is for gusts in the 90 – 100km/h range in the warned regions.

A peak strength near 980mb is quite intense but the storm will steadily weaken moving across SK and towards MB later in the week.

Farther out towards the end of the month it appears there could be some broad reinforcement of lower heights and unsettled conditions in the region while stout ridging returns to the west.
