Hurricane Michael has made landfall in Florida as a Category 4 hurricane with winds up to 249 km/h — the most powerful hurricane to hit mainland U.S. in nearly 50 years.

Evacuation orders were given to 500,000 people as the hurricane made landfall at Florida’s Panhandle, where 30 centimetres of rain and waves up to four-metres-high were expected.

As opposed to Hurricane Florence that struck the Carolinas in a slow, halting manner, Michael grew stronger quickly as it drew near shore.

The Florida region is bracing for “major infrastructure damage,” specifically to electricity distribution, wastewater treatment systems and transportation networks, Jeff Byard, associate administrator for the Federal Emergency Management Agency (FEMA), told reporters on a conference call.

The storm already had a significant impact on offshore energy production. U.S. producers in the Gulf cut oil production by about 40 per cent and natural gas output by 28 per cent on Tuesday, the Bureau of Safety and Environmental Enforcement said.

U.S. President Donald Trump has declared a state of emergency for the entire state of Florida, freeing up federal assistance to supplement state and local disaster responses.

After Florida, the storm is expected to hit Alabama, Georgia, the Carolinas — which is still reeling from flooding from Hurricane Florence — and then into Virginia.

The last major hurricane to hit the Panhandle was Hurricane Dennis in 2005.

Gaining fury with every passing hour, Hurricane Michael closed in Wednesday on the Florida Panhandle with potentially catastrophic winds of 150 mph, the most powerful storm on record ever to menace the stretch of fishing towns, military bases and spring-break beaches.
