Storm passed, frost is back. The Coquihalla work zones are the only score on the board.

Alberta — Highway 2 (QEII)

QEII: storm passed — mostly dry with ice in places, minus 5 tonight

Friday's storm is out and Saturday dawns cold and mostly dry on the QEII. The 5:16 a.m. corridor read showed Highway 2 mostly dry with ice in places, lowest minus 7°C and winds to 25 km/h, and no Environment Canada warnings in force as of that check. At 5:00 a.m. Edmonton Blatchford read minus 0.3°C with northwest winds at 24 km/h, and Calgary International read minus 1.3°C with northwest winds at 13 km/h. Environment Canada calls for a mainly sunny day in Edmonton (high plus 3, morning wind chill minus 8) and a mix of sun and cloud in Calgary (high plus 3, morning wind chill minus 9). Tonight both cities fall to minus 5, with wind chill minus 8 in Edmonton and minus 9 in Calgary — cold, but below every scoring threshold.

Alberta — Highway 16 (Yellowhead)

Yellowhead: dry with ice in places, Jasper wind chill minus 10 tonight

At the Jasper end, the 5:00 a.m. reading was minus 5.0°C and calm.

Sunday clears near noon at Jasper with a high of zero, then a clear Sunday night low of minus 8. No closures, no restrictions on the corridor.

British Columbia — Highway 5 (Coquihalla)

Coquihalla open — two work zones on their last day, rain tonight at Merritt

Highway 5 between Hope and Kamloops stayed open to through traffic overnight with no incidents reported, checked at 4:00 a.m. PDT. The two work zones remain in effect through today, Oct 24: lane closures one direction at a time at the Nicolum Creek Bridge and paving-related lane closures in both directions. Drive times are running only a few minutes over typical — 1 hour 54 minutes southbound and 1 hour 56 minutes northbound against a typical 1 hour 51 minutes. Environment Canada's Merritt forecast (the latest on file, issued Friday 4:00 p.m. PDT) calls for a cloudy Saturday with a 60 percent chance of showers, snow level 1,000 metres, high 7, and Saturday night periods of rain with the temperature steady near plus 3. No chain-up requirement is posted; the standing BC chain season (winter tires or chains on designated mountain routes since Oct 1) remains in force.

Ontario — Highway 401 (Windsor–Toronto–Kingston)

401: running but slow in Toronto — Milton maintenance, warm and clear tonight

The 401 corridor is running but slow through Toronto this morning: the live traffic read at 4:46 a.m. EDT showed the 401 west, central and east sections all slow across 235 Toronto cameras, with 44 active Toronto-area incidents in total. The one current 401 item is nightly maintenance on the 401 westbound between Regional Road 25 and Guelph Line in Milton, rated moderate — lane-level work, not a corridor closure. The most serious Toronto-area item this morning is elsewhere: a collision on the 404 northbound at Steeles Avenue. Environment Canada's Toronto-area forecast is the warmest of the four corridors: sunny today, high 16, and tonight clear with a low of plus 3 and a risk of frost. No EC alerts are shown for the corridor.

Prairies — Saskatchewan & Manitoba (storm tail)

Storm tail: gusts to 80-plus across SK/MB, northern snow totals still climbing

The same system that hit Alberta on Friday keeps working the eastern Prairies. The Weather Network reports that warnings remain in effect for high winds and winter storm conditions, with gusts of 50 to 80-plus km/h persisting through Saturday across Saskatchewan and Manitoba and easing into the overnight hours. Sudden reductions in visibility were expected late Friday into early Saturday across southern Saskatchewan as brief but intense snowfall accompanied the gusts, and high snowfall rates continue into the weekend across northern Saskatchewan and Manitoba, with 20 to 50-plus cm of accumulation likely by the end of the storm in the hardest-hit areas. The Weather Network also flags a possible additional light snowfall for Alberta on Sunday, confined to the Rockies and foothills. This item is Weather Network reporting, not an Environment Canada statement.

Bottom line for drivers

The storm has moved on and the board is nearly clean: frost and ice in places are the Alberta hazards this morning, the Coquihalla's work zones are the only scored item, and the prairie storm's tail is still blowing across Saskatchewan and Manitoba. Check 511 and Environment Canada before rolling, and expect a cold, clear Saturday night across Alberta.
