Firefighters and police officers have closed a road in Tenby because of fears that a flat roof is in danger of being blown into the path of passing traffic.
The incident involves a building close to the resort's Fourcroft Hotel, above the North Beach.
Traffic was stopped from using The Croft road for much of the afternoon.
But this evening, police officers are grouping vehicles into convoys before escorting them past the scene.
