The Foreign Office is advising against all but essential travel to Acapulco after a strong hurricane devastated the resort city.
Hurricane Otis caused significant damage to infrastructure in the Mexican Pacific coastal city with up to 40 people reported to have been killed and others missing.
The Mexican government is offering buses to Mexico City for affected tourists.
Acapulco airport re-opened on Friday, but only for flights transporting stranded tourists to the Mexican capital. Normal commercial flights are still not operating.
Acapulco was among the areas worst hit in Mexico, with 80% of the resort’s hotels reported to have been damaged and streets flooded.
“There have been reports of looting and robbery, given the scarce supplies of food, water and fuel,” the latest travel advice from the Foreign. Commonwealth & Development Office (FCDO) said.
Roads in the region have been subject to flooding, mudslides and traffic accidents.
“The National Guard have deployed to the region to help with disaster efforts. You should follow the advice of local authorities, including the National Guard,” the FCDO added.
Otis struck the south coast of the country last Wednesday as a Category Five hurricane, bringing winds of up to 165mph.
Hotels, transport, communications and health services have been affected across the region.
“The post-storm situation remains dangerous in Acapulco and the wider state of Guerrero. There may be further flash flooding and mudslides.
“Be aware that historically more accidents occur post-storm than during it. The storm is not the only hazard; many electric lines may be down and some buildings may not be structurally sound.
“For more information, stay in touch with your accommodation provider and monitor communications from local authorities.”
