Trump's visit came the day after police in Hollywood, Florida, launched an criminal investigation into a nursing home where eight patients died after the facility lost power and continued to operate with little or no air conditioning in sweltering heat.
At least 34 people have died in the USA under Irma-related circumstances, the vast majority in Florida.
Hurricane Irma slammed into Southwest Florida last weekend, destroying buildings and snapping trees after causing more extensive damage on the Florida Keys.
The two storms combined killed about 150 people in the US and the Caribbean islands and caused more than $30 billion in estimated damages, and Harvey brought record rainfall to Texas.
Florida's southwestern coast is a haven for retirees seeking warm weather and lovely sunsets across the Gulf of Mexico.
Power outages also remain an issue in the Jacksonville area. Almost 2.7 million homes and businesses, about 1 in 4 Florida customers, were still without power Thursday.
The shocking news that eight people who were residents of the Rehabilitation Center at Hollywood Hills in Hollywood, Fla., died at the facility in the aftermath of Hurricane Irma has sparked many questions about how such a thing could happen. "Our most important concern to ensure they were hydrated and as comfortable as possible", said Carballo in a statement.
Police said a criminal investigation is underway and they are not ruling anything out. "It was very hot on the second floor".
The five women and three men ranged in age from 70 to 99.
Police said the causes of death were not immediately known.
ACCORDING TO BRADY: Is this what a changing climate looks like?
Now, while the world is watching Trump and his band of denying fools squirm, is the flawless time to force them into action. "Absolutely", said CNN senior meteorologist Brandon Miller, who has studied global warming for more than a decade.
Mara K. Gambineri, spokeswoman for the state health department, told the Herald, "At no time did the facility report that conditions had become unsafe or that the health and safety of their patients was at risk".
The ex-husband of 71-year-old victim Gail Nova said her devastated family believes the facility should lose its license.
Fifty-seven residents were moved from a suburban Fort Lauderdale assisted-living facility without power to two nearby homes where power had been restored.
"I am going to work to aggressively demand answers on how this tragic event took place", Governor Rick Scott said in a statement.
"This situation is unfathomable", he said.
Fire and rescue teams were first called to the facility at about 3am for a patient reported in cardiac arrest, and firefighters returned an hour later for a resident with breathing difficulties, the city said.
Total insured losses from the storm are expected to run about $US25 billion, including $US18 billion in the United States and $US7 billion in the Caribbean, catastrophe modeler Karen Clark & Company estimated on Wednesday.
In the battered Florida Keys, meanwhile, county officials pushed back against a preliminary estimate from the Federal Emergency Management Agency that 25 per cent of all homes in the Keys were destroyed and almost all the rest were heavily damaged.
US President Donald Trump has arrived in Florida for his third visit in three weeks and praised emergency services as the reason "thousands and thousands of people" didn't die during Hurricane Irma.
Irma hit much of the Caribbean, including Antigua, Barbuda, St. Martin, St. Barts, Anguilla, Cuba, the British Virgin Islands, Turks and Caicos, and the Bahamas.
Parts of the US Virgin Islands also lay in Irma's path, though Trump does not now have plans to stop there.
