First Bus will suspend all Glasgow services over Storm Eowyn on Friday.
The travel giant has issued a warning to passengers to heed the "do not travel" guidance over the rare red weather alert.
Bosses have made the move to temporarily halt all buses across Greater Glasgow after the Met Office said the weather could be a "danger to life".
The services will be stopped from 8am tomorrow "to return all vehicles and colleagues to their depots safely".
They will not operate again until after "the worst of the weather has passed" and routes have green lit as safe to recommence.
Duncan Cameron, managing director of First Bus Scotland said: “Following strong advice from the relevant authorities including the First Minister and Police Scotland, First Bus will be temporarily suspending all services across Greater Glasgow ahead of the red weather warning.
“We’re advising all passengers to follow the advice given by not travelling tomorrow.
"Our network of routes will begin to be withdrawn from 0800 to allow us to return all vehicles and colleagues to their depots safely.
“These measures are being implemented in the interests of the safety of our people and passengers which are our utmost priority.
“Services will not resume until after the worst of the weather has passed and routes have been assessed as safe for operations to recommence.
"Pending the status of the red weather warning, we expect services to gradually be reinstated after approximately 1800.”
