President Joe Biden and first lady Jill Biden will travel to Puerto Rico on Monday, and Florida on Wednesday to survey the damage from Hurricane Fiona and Hurricane Ian, respectively, the White House announced Saturday night.

Biden had previously said he would visit Florida to see the destruction in person, and that it was his "intention" to do the same for Puerto Rico.

Florida’s death toll from Hurricane Ian has climbed to at least 72, according to information from local officials.

Lee County, which encompasses Fort Myers, accounts for the majority of the fatalities, with at least 35 lives lost in the county, according to the Lee County Sheriff’s Office.

In Charlotte County, which is home to Punta Gorda, the preliminary death toll is 23, the Charlotte County Sheriff's Office told ABC News.

Other fatalities were reported in Sarasota, Volusia, Lake, Collier, Hendry and Manatee counties.

Despite the "complete devastation" in Lee County, Sheriff Carmine Marceno said Saturday that "there's light at the end of the tunnel. ... We are going to be stronger than ever."

"We are one big family together. That's what makes us great. And sometimes these horrific events bring us all together for us to move forward," Marceno said.

Over 1.05 million customers remain without power in Florida on Saturday, days after Hurricane Ian tore through the state.

Another 56,800 customers are without power in North Carolina and more than 17,000 are in the dark in Virginia after Ian and its remnants moved north.

More than 1,100 Floridians have been rescued by the Florida National Guard in the wake of Hurricane Ian, according to state officials.

The rescues include 1,076 people evacuated from flooded areas in southwest and central Florida as of Saturday morning, as well as 78 people transported from a flooded nursing home facility, Gov. Ron DeSantis' office said in a press release.

Caribbean islands such as Jamaica and Grand Cayman will start to experience the effects from the outer bands of Tropical Storm Ian within the next 24 hours, forecasts show. The islands will experience conditions such as heavy rain, possible flash flooding and storm surge.

The storm system will begin to rapidly intensify overnight into Monday before it closes in on western Cuba on Monday night.

As of 2 p.m., the sustained winds in the tropical storm remained at 50 mph as it moved west-northwest at 12 mph, the center about 265 miles away from Grand Cayman.

Hurricane warnings are in effect for Grand Cayman and western Cuba, while tropical storm warnings and watches are in effect in other portions of both islands.

As a hurricane, Ian is expected to peak at a Category 4 before weakening slightly as it looks to make landfall on the west coast or panhandle of Florida in the coming days.

There is still some uncertainty to the track Ian will take once the system enters the Gulf of Mexico.

The center of the storm and the worst of the impacts could end up heading toward the western coast of Florida's peninsula, including the Tampa area. The other possible scenario has the storm moving more due north and bringing a possible landfall along the Florida peninsula, impacting cities like Panama City and Tallahassee with more direct effects.

The storm will begin to impact the Florida keys and the southern portions of the state by Tuesday night.
