Hurricane Ian updates: Florida death toll climbs

NASA said it will roll the Artemis I rocket off the launch pad and back to the vehicle assembly building on Monday night due to the storm.

“Managers met Monday morning and made the decision based on the latest weather predictions associated with Hurricane Ian, after additional data gathered overnight did not show improving expected conditions for the Kennedy Space Center area,” NASA said in a statement. “The decision allows time for employees to address the needs of their families and protect the integrated rocket and spacecraft system.”

As Ian approaches, here are a few commonsense strategies to help avoid unnecessary risk from floodwaters:

--Before flooding, look up your neighborhood's flood zone and determine if your home or business is prone to flooding. Come up with an evacuation plan and make sure your car has a full tank of gas. Stock up on non-perishable foods.

--After flooding, ensure your drinking water is sanitized and wash your hands thoroughly after contact with floodwaters. Disinfect objects that have come into contact with floodwater before offering them to children or toddlers.

--Try to avoid exposure with floodwaters for long periods of time to prevent physical injury. Wear waterproof boots if you have them. Do not attempt to drive over flooded streets as it could damage the car and strand passengers.

The White House is “closely monitoring” the hurricane, a White House official told ABC News.

President Joe Biden approved Florida’s emergency assistance request this weekend “as soon as he received it,” the official said.

“He also directed his team to surge Federal assistance to the region well before landfall,” the official said. “FEMA has already deployed staff there and pre-positioned food, water, and generators.”

Biden was scheduled to travel to Florida this week but that trip has been postponed due to the storm.

Ian is expected to become major Category 3 hurricane Monday night with winds of 115 mph.

As Ian passes Cuba, it’s expected to rapidly intensify, becoming a Category 4 hurricane as it moves through the Gulf. Hurricane warnings are in effect for Cuba and the Cayman Islands.

Models are split when it comes to Ian’s landfall in Florida; impacts could be as far north as Panama City and as far south as Fort Myers.

Some models forecast landfall by Wednesday afternoon between Tampa and Fort Myers, while other models predict landfall at the end of the week near Panama City or Apalachicola.

Hurricane watches have been issued in Tampa, Fort Myers and Naples.
