The powerful storm came ashore near Keaton Beach on Wednesday morning

Hurricane Idalia made landfall in Florida on Wednesday morning.

The powerful storm came ashore near Keaton Beach as a Category 3 storm after having intensified in the Gulf of Mexico this week. It was expected to be a Category 4 storm, but was downgraded less than an hour before hitting land.

That doesn't mean Idalia isn't dangerous. As the storm made its way to shore on Wednesday morning, it was moving at 18 mph as a hurricane, with wind speeds upwards of 125 mph and a storm surge upwards of 16 ft. It's the strongest storm that has made landfall in the Big Bend region in more than 125 years, according to CNN.

Upwards of 18 million people have been impacted by the hurricane storm warnings, with approximately 161,000 people are without power, according to poweroutage.us. The storm's expected path is along the north, through Tallahassee. Tornado warnings are also in effect.

Weather experts say it'll likely be a tropical storm by the time it hits Charleston, South Carolina and Wilmington, North Carolina.

The Federal Emergency Management Agency is ready and waiting to react to the impacts, FEMA officials saying in a release they're "ready to move to the most impacted areas immediately after the storm passes" with "warehouses filled with commodities like food, water, blankets, and medical supplies that ready to rapidly move into the impacted area at the state’s request."

Prior to making landfall, the storm passed over western Cuba on Monday, then passed by the southeastern Gulf of Mexico the following day, according to the National Hurricane Center. More than 10,000 people in Cuba left their homes for safety as up to 4 inches of rain was recorded, reported the Associated Press.

The storm strengthened on Tuesday into a Category 2 hurricane with 100 mph winds on Tuesday, according to CNN.
