Hurricane Ian will make landfall in Florida this afternoon after it strengthened to a Category 4 storm overnight.

According to the 5 a.m. update from the National Hurricane Center, Ian is currently about 75 miles south-southwest of Punta Gorda, Florida, moving north-northeast at 10 mph.

The storm now features maximum sustained winds of 155 mph, which is just 2 mph hour away from a Category 5 hurricane.

Ian’s path hasn’t changed since the 11 p.m. update, but as of now, the storm’s eye will likely make landfall between Venice and Fort Myers at around 2 p.m. on Wednesday, bringing “life threatening” storm surge to the Lee and Charlotte counties.

“Catastrophic storm surge inundation of 12 to 16 feet above ground level along with destructive waves are expected somewhere along the southwest Florida coastline from Englewood to Bonita Beach, including Charlotte Harbor,” said the NHC. “Residents in these areas should urgently follow any evacuation orders in effect.”

Although the “cone of uncertainty” shifted south last night, forecasters say residents in Tampa Bay can still expect hurricane force winds and heavy rain, as well as flash flooding and power outages. The one big change over the last 48 hours for Tampa Bay will be storm surge, which forecasters say will be less of a problem for the area.

Tropical force winds are also expect to arrive in the region as early as 8 a.m.

Ian is expected to weaken after it makes landfall, says the NHC, but conditions will still be extremely dangerous as it barrels towards Polk County and Orlando.

“Catastrophic wind damage is expected along the southwestern coast of Florida beginning in the next few hours where the core of Ian makes landfall. Preparations to protect life and property should be urgently rushed to completion,” says the NHC. “Heavy rainfall will spread across the Florida peninsula through Thursday and reach portions of the Southeast U.S. later this week and this weekend,”

A Hurricane Warning remains in effect for most of the Tampa Bay area, including Hillsborough, Pinellas, Manatee, Sarasota, Highlands, Polk, Desoto, and Hardee counties.

Hillsborough County has ordered mandatory evacuations for residents of zones A and B., while Pinellas and Pasco have ordered evacuations for A, B, and C.
