The death toll from Hurricane Alex in the northern Mexican state rose to 15 and the preliminary estimate of the damage hit 770 million U.S. dollars, the Mexican governor said on Tuesday, Xinhua reported.
Rodrigo Medina de la Cruz, governor of northern state Nuevo Leon, said around 140,000 people do not have access to food and water in the state, which remains in a state of emergency.
In the state capital Monterrey, water was selling nearly four times higher than normal as panic buying had emptied the supermarkets, local broadcaster reported on Sunday.
"We are working without pause and our number one priority is the restoration of water supply," Medina told media on Tuesday. "It is difficult to say when things will return to normal."
The worst hit areas were the capital city and the nearby cities of Santa Catarina and Garcia, Medina added. He also made an appeal for volunteers, water, food, personal hygiene items and cleaning equipment.
The storm struck Nuevo Leon's neighbor Tamaulipas as a category two Hurricane on Wednesday last week.
Before hitting northern Mexican, it had caused eight deaths in the rest of Mexico and 10 others across Nicaragua, El Salvador and Guatemala.
A group representing Monterrey business owners said that the disaster has prevented 25,000 people from showing up for work on Friday.
