The Met Office has upgraded the weather warnings issued for North and East Yorkshire this weekend.
From 4pm tomorrow to 9am on Sunday, there is an amber warning for snow and ice.
This is reported to be expected to mostly affect Selby and its surrounding areas.
However the Yellow warning remains further north.
Strong easterly winds will lead to some temporary blizzard conditions and drifting of snow.
Travel delays on roads are likely, stranding some vehicles and passengers.
Some delays and cancellations to rail and air travel are likely.
There is also a yellow warning for snow and ice in York, Thirsk and Northallerton.
On Sunday, snow showers will continue which could prove disruptive.
There is a chance that power cuts will happen, and some rural communities could be cut off.
Ice on roads, pavements and cycle paths is likely either where melted snow refreezes or where further wintry showers occur.
This increases the risk of accidents, as well as injuries due to falls.
Drivers are being urged to be prepared before setting out on journeys after Highways England issued a severe weather alert for snow.
Highways England has also issued an amber 'be prepared' alert for the North which will come into force at 7pm tonight (Friday) and run until 5am on Saturday morning, with up to 10cm of snow expected on higher routes.
Drivers are being advised to avoid trans-Pennine roads, including the M62 (junctions 21 to 25), A628 and A66, if at all possible as well as the M1 between junctions 35 (Rotherham) and 47 (Garforth), the M606 near Bradford and the M621 near Leeds.
"Our gritter drivers will be out treating our roads around the clock but it is still important to drive to the conditions when snow is forecast.
Make sure you keep your distance and reduce your speed if you need to travel because, even in conditions that seem normal and when the snow is not settling, it can be slippery if ice patches have formed, or where fresh salt has not been worked into the carriageway.
Highways England is advising drivers to pay attention to messages on the overhead electronic signs and listen for Minster FM radio updates.
