Volkswacht Bodensee - Cuba, Florida brace for Hurricane Ian

Authorities in Havana said they were ready to evacuate those from the most affected areas while also organizing fresh drinking water supplies and medical services.

The US National Hurricane Center (NHC) warned Ian was intensifying and could pass over western Cuba late Monday and early Tuesday.

"Maximum sustained winds have increased to near 85 miles (135 kilometers) per hour with higher gusts," it said.

"Rapid strengthening is expected during the next day or so, and Ian is forecast to become a major hurricane."

Cuba's Insmet meteorology institute said Ian was advancing at a speed of 22 kilometers per hour.

The six provinces put on alert are Pinar del Rio, Artemisa, La Habana, Mayabeque, Cienfuegos and Isla de la Juventud.

- 'Huge storm surge' expected -

In Florida, the city of Tampa was under a hurricane watch, and Governor Ron DeSantis declared a state of emergency in all 67 counties as officials scrambled to prepare for the storm's forecast landing on late Wednesday or Thursday.

Ian "will bring heavy rains, strong winds, flash flooding, storm surge, along with isolated tornado activity along Florida's Gulf Coast," DeSantis said at a press conference in Tallahassee on Monday.

He warned people to prepare for power cuts.

"Even if the eye of the storm doesn't hit your region, you're going to have really significant winds, it's going to knock over trees, it's going to cause interruptions," DeSantis said, warning of likely flooding.

The governor urged residents to stock up on food, water, medicine and fuel, and he activated 7,000 National Guard members to help with the effort.

Authorities in several Florida municipalities, including Miami, Fort Lauderdale and Tampa, started distributing free sandbags to residents to help protect their homes from the risk of flooding.

President Joe Biden approved emergency aid to 24 counties in Florida through the Federal Emergency Management Agency (FEMA).

NASA said it was rolling back its massive Moon rocket into its storage hangar at the Kennedy Space Center in Florida due to the hurricane.

- Fiona's wake -

The Caribbean and parts of eastern Canada are still counting the cost of powerful storm Fiona, which tore through last week, claiming several lives.

When it arrived in eastern Canada, the storm packed intense winds of 80 miles per hour, bringing torrential rain and waves of up to 40 feet (12 meters).

Three people are believed to have died when Fiona barreled into Canada's Atlantic provinces as a post-tropical cyclone early Saturday.

Prince Edward Island authorities confirmed the death of one person while officials in Newfoundland said they found the body of a 73-year-old woman believed to have been swept from her home. She was apparently sheltering in her basement when waves broke through.

A third person has been reported missing in Nova Scotia -- one of the hardest-hit provinces -- and is presumed dead

"The devastation is immense," Nova Scotia Premier Tim Houston told reporters. "The magnitude of the storm is incredible."

Storm surges swept at least 20 homes into the sea in the town of Channel-Port aux Basques, on the southwestern tip of Newfoundland.

Around 200 residents had been evacuated before the storm hit.

"Some people have lost everything, and I mean everything," Mayor Brian Button told CBC News.
