An intense low-pressure system draped higher elevations - including the Coquihalla Highway and Merritt connector - with snow and hazardous driving conditions over the weekend.
The storm left about 24 centimetres on the Coquihalla and 36 centimetres on the connector, hardly out of the ordinary for mid-fall but something of a cold shock after a mild October.
Several motor vehicle accidents were reported on Sunday near the Logan Lake exit on the Coquihalla.
Itinerant weather forced the cancellation of a search-and-rescue exercise planned for the Red Lake area on Saturday.
Kamloops Search and Rescue had planned to conduct a search based on the RCMP's cold-case investigation of the disappearance of Edna Bette-Jean Masters in 1960.
The weather dumped on that plan with heavy rain and snow accumulations at higher points.
"We did have a lot of searchers come down from all over the southern Interior, so it was kind of disappointing for everybody," said Alan Hobler, KSAR search manager. "We thought the best thing to do was to postpone until spring."
KSAR anticipated a weather problem. It wasn't aware of the cold case investigation until September. The Masters search was delayed by another search in the North Thompson for Vern Boettger, a Vavenby man who hasn't been seen since Oct. 6, Hobler said. That search has so far turned up nothing.
They considered staging the search as a discrete training exercise, but thought better of it. Although it would have been unlikely to have found any clues about the Masters child, there was risk of damaging whatever might conceivably remain, he said.
In any case, snow cover precluded a thorough search.
More snow, mixed with rain, is forecast to arrive later in the week, starting on Thursday.
