US President Donald Trump said on Thursday that restoring electricity was a priority as he headed to storm-ravaged Florida, where eight retirees died after Hurricane Irma knocked out power to their nursing home.
A hurricane formed off the southwestern coast of Mexico, meanwhile, triggering warnings of life-threatening storm conditions for a long stretch of coastal communities including the resort city of Acapulco, forecasters said.
In Florida, more than four million people were still without electricity on Thursday, four days after Irma made landfall in the Florida Keys as a powerful Category Four storm.
Trump, speaking at the White House before flying to Fort Myers, Florida, said the federal and state authorities were "doing a great job on power."
"There's never been anything like this," he said. "We have the largest assemblage of human beings ever in one area for power, and rapidly it's being turned on."
Florida Governor Rick Scott said earlier this week that 30,000 utility workers from out of state were helping with the effort to restore electricity in the state.
Florida authorities, meanwhile, have launched a criminal investigation into the eight deaths at a nursing home in Hollywood, north of Miami, which had been without air conditioning since Irma struck.
Governor Scott said he was "absolutely heartbroken" to learn of the "unfathomable" deaths at the facility and promised to "aggressively demand answers."
Three of those who died were in their nineties, including 99-year-old Albertina Vega. The youngest was 70, according to the Broward County Medical Examiner's office.
The deaths brought the total number of storm-related fatalities in Florida to 20, and illustrated the urgency of restoring power.
Trump to meet victims  
Trump and his wife, Melania, will be briefed on hurricane recovery efforts in Fort Myers and then head to nearby Naples to meet storm victims, the White House said.
As Trump visited Florida, French President Emmanuel Macron wrapped up a visit to the French overseas territories of Saint Martin and Saint Barts, two Caribbean resort islands which were devastated by Hurricane Irma.
The storm left around 40 people dead in the Caribbean before churning east and pounding Florida.
Macron pledged on Wednesday on Saint Barts, population 9,000, that an emergency relief fund for victims would be operational by Monday.
France, Britain and the Netherlands have been criticised for the pace of relief efforts for their overseas territories ravaged by the storm.
Islanders have complained of a breakdown in law and order and widespread shortages of food, water and electricity.
Touring Saint Martin, Macron was at times jeered by people waiting for aid supplies or hoping to catch flights to France to escape the devastation across the island.
British Foreign Secretary Boris Johnson visited the British Virgin Islands and Anguilla on Wednesday and pledged "absolute commitment" to Britons there.
The Miami-based National Hurricane Center said meanwhile that Hurricane Max was swirling in the eastern Pacific about 40 miles (65 kilometers) southwest of Acapulco and expected to make landfall Thursday afternoon.
As of 10:00 am, the Category One storm had top winds of 80 miles (130 kilometers) per hour and was moving east at seven miles (11 kilometers) per hour, the NHC said.
Authorities declared a hurricane warning for 300 miles (485 kilometers) of Mexico's coast stretching from Zihuatanejo to Punta Maldonado.
"Preparations to protect life and property should be rushed to completion," the hurricane center warned.
Max was expected to bring dangerous storm surge that will likely cause "significant" coastal flooding, accompanied by "large and destructive waves."
Guerrero state and parts of Oaxaca state were forecast to receive five to 10 inches (12.7 to 25.4 centimeters) of rain, with some areas receiving more than 20 inches.
The rainfall could cause "life-threatening flash floods and mudslides," the NHC said.
