People living around the western Gulf coast in Mexico and the US state of Texas have been urged to move to storm shelters as another major hurricane approaches.
Texan officials are giving out sandbags and warning there to prepare for flooding as a tropical storm, named Hermine, heads towards land.
In late June Hurricane Alex killed at least 12 people in north east Mexico as it drenched the land for days − Hermine will be the second major storm so far this season.
“We urge the general population to be on alert for possible floods and mudslides.”
Salvador Trevino, Tamaulipas state civil defence director
Miami’s National Hurricane Centre said Hermine is likely to become hurricane strength as it hits a relatively empty area 80km south of Matamoros city, near Brownsville, Texas.
Residents of Rio San Fernando in Mexico were issued with a hurricane alert, which also applies all the way up the coast to Baffin Bay, Texas.
Emergency officials in Mexico have said anyone living in a low lying area along the coast should move to a storm shelter.
Tamaulipas state civil defence director Salvador Trevino said: “We urge the general population to be on alert for possible floods and mudslides.”
Pumping equipment is being prepared by officials along the Texas coast and residents of Cameron County are being distributed with sandbags, county emergency management coordinator John Cavazos said.
He added that emergency workers are asking people who are staying in recreational vehicles in parks along the coast to move inland.
The ground across the region is already saturated with water because of recent rains.
Cavazos said some areas may find they get as much as a foot of rainfall, adding: “Anyone living in an area that’s known to flood needs to take some precautions.”
