Coquihalla Highway - Hope to Merritt
Snowfall Warning

▶

12:55 a.m. PST Friday 19 December 2025

Snowfall Warning in effect for:

Coquihalla Highway - Hope to Merritt

A long period of heavy snowfall is expected.

When:
Light snow overnight and then a series of low pressure systems will bring rounds of precipitation on Friday and Saturday.

Where:
- Coquihalla Highway (Near Coquihalla Summit)

Additional information:
As a frontal system approaches the B.C. coast, we expect to see close to 10 cm of snowfall accumulation for the Coquihalla Highway tonight. Strong wind gusts of up to 80 km/h and heavy snowfall could lead to blowing snow conditions this evening.

A series of low pressure systems will then make its way through the B.C. interior on Friday and Saturday. The Coquihalla summit will receive another 15 -25 cm on Friday and possible accumulation of 20-30 cm on Saturday. There is some uncertainty on the snowfall accumulation into the weekend.

Travel will likely be challenging. Visibility will likely be reduced at times. Road closures are possible.

Weather in the mountains can change suddenly resulting in hazardous driving conditions.

Prepare for quickly changing and deteriorating travel conditions. The site https://shiftintowinter.ca/ reminds drivers to know before you go. Adjust to winter driving behaviour and use winter tires and chains.
