Forecasters have warned drivers to drive carefully as Storm Bert is expected to bring a "multi-hazard event" of wind, rain, and snow over a large portion of the United Kingdom. The Met Office has issued a yellow alert for portions of the United Kingdom and a more severe amber warning for Scotland for Saturday and Sunday, according to a report in The Guardian. Parts of the UK will experience significant weather events due to Bret, the second named storm of the season. In certain places, strong rain and wind gusts of up to 70 mph (113 kmph) are predicted.

"We're looking at strong winds, some high snowfall accumulation, heavy rain, all in various different parts of the UK. So it's quite a complex weather set-up for the weekend. Generally speaking, it's a very unsettled weekend of weather ahead," Oli Claydon, a spokesperson for the Met Office, told The Guardian.

"Further south, it's wind and rain, further north it's snow then rain and wind. So it really depends on where you are in the UK. Keep on top of the forecast for your area and prepare as necessary," he added.

Storm Bert is expected to reach the UK on Saturday.

The amber warning for Scotland covers parts of Angus, Perth and Kinross, Stirlingshire, Aberdeenshire and some of the Highlands and Argyll and Bute. The warning will be in place from 7am to 5pm (local time) in Saturday.

Temperatures have dipped below freezing all week, with snow and ice settling across the north of Scotland, reported the BBC.

The extreme weather warning has already led to closure of dozens of schools across the UK and Scotland, and deferred timings for several others.

Scottish government agency Transport Scotland said roads may be affected by deep snow, particularly over higher routes, and some rural communities might be cut off.
