Hurricane Ian updates: Florida death toll climbs
Lee County, which encompasses Fort Myers, accounts for most of the fatalities.
The remnants of Ian are charging up the East Coast on Saturday after making landfall as a Category 1 hurricane in South Carolina on Friday afternoon.
The monster storm made its first U.S. landfall on Wednesday on Florida's west coast as a powerful Category 4 hurricane, shredding homes with ferocious winds topping 150 mph. Florida's death toll has climbed to at least 81, according to information from local officials.

NASA to reconvene on whether to take Artemis rocket off launchpad
NASA hasn’t decided whether to leave its Artemis I rocket on the launchpad as it monitors Tropical Storm Ian's path toward Florida, the agency said Sunday.
The federal space agency’s mission managers will continue discussions on Monday about the next steps as its rocket was delayed again.
On Saturday, NASA scrapped its third planned launch attempt of Artemis I because of weather concerns. Artemis I was scheduled to launch on Sept. 27.
Engineers will decide if the rocket needs to roll back off the launch pad. If they do not roll it back, the next possible launch date is Sunday, Oct. 2.
Tropical Storm Ian is forecast to strengthen into a major hurricane as it nears Florida.
NASA had to scrub the first launch attempt on Aug. 29 because of a faulty temperature sensor and the second attempt on Sept. 3 due to a liquid hydrogen leak.
If the Oct. 2 launch doesn’t happen, the rocket will be taken back to the Vehicle Assembly Building at the Kennedy Space Center until the team decides on the next date.

Ian strengthens once again, forecast to become hurricane on Monday
Tropical Storm Ian has strengthened with maximum sustained winds at 60 mph and is expected to get stronger throughout the night as atmospheric conditions become more favorable for the storm.
Ian is forecast to become a hurricane on Monday, becoming even more intense likely into Tuesday.
Ian is moving to the northwest to the Northwest at 12 mph, with the center located 160 miles away from Grand Cayman.
Jamaica and the Cayman Islands are expected to experience heavy rain, a heavy surge and possible flash flooding over the next 24 hours.

Ian weakens slightly but will regain strength overnight
Tropical Storm Ian has weakened slightly, but it is expected to not only strengthen but rapidly intensify overnight as it travels over warm waters in the Caribbean.
As of 5 p.m. ET, the storm system had maximum sustained winds of 45 mph and was moving west-northwest at 12 mph, with the center located about 220 miles away from Grand Cayman.
Dry air ahead of the storm has delayed the strengthening trend so far. But the rapid intensification is expected to occur Monday into Tuesday as the system continues across the northwestern Caribbean and closes in on western Cuba.
Over the next 24 hours, the outer bands will impact Jamaica and the Cayman Islands, bringing rounds of heavy rain, possible flash flooding and storm surge. Later Monday and into Monday night, Ian will be closing in on western Cuba and will likely bring significant wind and storm surge impacts to the region.
A hurricane warning is in effect for Grand Cayman and portions of western Cuba. A tropical storm watch has been issued for portions of western Cuba, as well as the lower Florida Keys, including Key West.
As of 5 p.m., the forecast track was nudged slightly eastward. Overall, the forecast guidance variability and uncertainty will remain high, and the track for where the storm will be from the middle to the end of the week will continue to shift over the next 24 to 48 hours.

Caribbean Islands to start experiencing effects from Ian by Monday
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.
