Hurricane Ian has been seen in the southeastern Gulf of Mexico as of late Tuesday morning, according to a National Hurricane Center advisory.

CNN News reported that Ian's winds have decreased only slightly after its trip across western Cuba. However, it keeps the storm at Category 3. The hurricane is expected to gain strength again later today and become a Category 4 before the day ends.

The Hurricane Center said in its forecast that Ian is expected to approach the west coast of Florida within the hurricane warning area on Wednesday and Wednesday night.

There is a projected highest surge, expected to be eight to 12 feet, which would occur south of Tampa Bay and north of Bonita Beach. It includes Charlotte Harbor and the cities of Port Charlotte and Punta Gorda.

The center added that its forecast on Ian is that it is seen to be an "extremely dangerous major hurricane."

Several Florida counties have expanded their mandatory evacuation order such as Hillsborough County and Manatee County.

Manatee County Administrator Scott Hopes said that those along the coast and prone to flooding should take the storm seriously and evacuate. Hopes said that it is a "worst-case scenario."

In Cuba, the entire island has been reported without any electricity after a collapse of the power grid, as announced by the Ministry of Mines and Energy. Officials are working to restore power through Tuesday evening and Wednesday.

Associated Press News noted that Ian had made landfall in Cuba's Pinar del Rio province, wherein officials had established more than 55 shelters and evacuated 50,000 people.

Cuba suffered a "significant wind and storm surge impact" due to Ian, according to the U.S. hurricane center.

Havana's El Fanguito, which is a poor neighborhood near the Almendares River, had residents living there packed up whatever they could, as reported by The Guardian.
