Forecasters have warned that heavy snowfall may bring significant disruption to travel across parts of central and northern Scotland as the warning remains in place until 9am on Friday, January, 29.
The warning covers the area between Perth, Stirling and Inverness.
It does reach towards Fort William but the heavy snow isn’t expected to cause major disruption in the area.
The warning continues further north than Inverness, affecting central and northern Scotland right up to Ullapool.
Forecasters have warned that some roads and railways may be affected by longer journey times so people should expect delays when travelling by bus, train or car.
Some services may be cancelled and there is a small chance of stranded vehicles and passengers.
They have also warned that there is a slight chance that some rural communities could become cut off due to the bad weather.
Furthermore, there is a small chance that due to the snow, power cuts will occur and other services, such as mobile phone coverage, may be affected.
A statement on the Met Office website says: “A band of snowfall will push north east into this region during the early hours of Thursday and become slow-moving before clearing during Friday morning.
"Snow may fall to lower elevations for a time with some locations seeing several cm by Friday morning.
"Above 200m elevation significant and prolonged snowfall is possible throughout Thursday before easing on Friday morning with the potential for 15-20 cm to accumulate which may lead to transport disruption.”
