A potent low-pressure system rolling up from Wyoming is expected to bring heavy rainfall and strong winds to parts of west-central Saskatchewan beginning Saturday, with meteorologists warning of localized flooding and wind damage through the weekend.
Forecasters say the system, aided by a deep upper-level trough crossing the Rockies and enhanced moisture from the south, is expected to stall over southern Saskatchewan, unleashing widespread rain and cooler-than-average temperatures. The storm will push eastward through the province overnight Saturday into Sunday.
Rainfall totals are expected to be significant, with 30 to 50 millimetres forecast for much of southern Saskatchewan. Communities such as Kindersley and Swift Current could see 50 to 75 millimetres by Monday, and some localized areas could exceed 100 mm.
We’re looking at a fairly substantial rainfall event across the region. It’s not out of the question that some pockets could see over 100 millimetres by the time this wraps up.
Gusty winds are also expected to accompany the system Saturday, raising concerns about downed trees and power lines as already-saturated soils could weaken root structures.
Officials are urging residents to prepare for the risk of flooding, especially in low-lying or poorly drained areas. Motorists are reminded not to attempt driving through flooded roads, where water depth can be dangerously deceptive.
While disruptive, the rain is welcome news for both farmers and firefighters, with many regions still playing catch-up after a dry start to the year. The precipitation will help replenish soil moisture and potentially reduce the threat of wildfires in the weeks ahead.
The system is expected to gradually taper off Monday, but cooler, unsettled conditions may persist into early next week.
