The number of people dead and missing due to Hurricane Otis, a Category 5 storm which hammered the Mexican Pacific resort city of Acapulco has risen to 100, officials say.
Otis battered Acapulco with winds of 265km/h on Wednesday, flooding the city, tearing roofs from homes, hotels and other businesses, submerging vehicles, and severing communications as well as road and air connections.
Looting broke out as the city's population of nearly 900,000 became increasingly desperate for food and water.
The government of Guerrero, Acapulco's home state, said in a statement that 46 people were dead and 54 others were missing.
On Sunday afternoon, Mexico's federal civil protection authorities said there were 48 dead, consisting of 43 in Acapulco and five in nearby Coyuca de Benitez.
Among the dead are a US citizen, a Briton and a Canadian, according to Guerrero's government.
Fishermen and workers on tourism yachts gathered at Acapulco's Playa Honda on Sunday afternoon to look for missing colleagues and friends, worried officials were not doing enough.
Luis Alberto Medina, a fisherman, said he was searching for six people who worked in the harbour.
"It was really horrible," Medina said. "We've already found the bodies of others."
Governor Salgado provided updated figures on the phone with President Andres Manuel Lopez Obrador, who during a regular government press conference urged local authorities to ensure that basic goods were being delivered to Acapulco's population.
The cost of damage from the hurricane could climb as high as $US15 billion ($A24 billion) according to estimates, and Mexico has sent some 17,000 members of the armed forces to keep order and help distribute tons of food and supplies in Acapulco.
Access to food and water remains challenging, and retail group ANTAD on Monday urged the government to step up efforts to prevent looting at stores run by its members. Members include Soriana and Chedraui.
"We condemn acts of robbery by the population," ANTAD said in a statement.
"There is no justification for it."
A line of some 150 people waiting for water provided by a local authority snaked down muddy streets in the La Frontera neighbourhood on Sunday afternoon, as residents holding empty water containers bemoaned the hours-long wait.
"Look how many of us there are," said one of them, Emilia Rojas, looking around her in despair.
"We're so many. This water isn't going to be enough."
On a nearby street, Perla Rubi said the long wait was uncomfortable, given how desperate people were.
"We've been here since dawn, since five in the morning, risking getting robbed, because now they're assaulting people in the streets," she said. "Where's the government help?"
The disaster struck Acapulco barely seven months before Mexico's next presidential election, and Lopez Obrador on Monday reiterated his claim that critics were attacking his response to Otis and inflating its impact for electoral reasons.
His fiery denunciations sparked criticism that the president was downplaying the gravity of the disaster.
