Authorities announced Tuesday that Hurricane Ian has knocked out power to the whole island of Cuba before making landfall in Florida over the next 24 hours.

In a statement, the state-run energy provider of Cuba, Unión Eléctrica de Cuba, reported that electricity was cut off to the entire island of around 11 million people and that restoration works were underway.

Tuesday morning, the Category 3 hurricane swept across western Cuba, devastating destruction and forcing the evacuation of numerous people.

Authorities are currently assessing the damage caused by the hurricane, although no casualties have been recorded as of yet.

Ian could grow to a Category 4 hurricane as it approaches the state of Florida, where it is predicted to strike the southwestern shore on Wednesday and expand northward throughout the week.

At least 2.5 million Floridians are under some form of evacuation order as of Tuesday, when Storm Ian rapidly strengthened into a major hurricane.

Residents in Tampa began their preparations to withstand the hurricane with minimal damage by stocking up on food and water at grocery stores. The most desired items included sandbags, generators, radios, and chainsaws.
