Hurricane Michael has made landfall along the Florida Panhandle.
It pummeled the coast near Panama City Wednesday afternoon.
Early Wednesday morning, forecasters upgraded Michael to an "extremely dangerous Category 4" storm with winds measuring around 140 mph.
The storm got even stronger as it headed toward Florida. When the storm made landfall, the National Hurricane Center reported Michael's maximum sustained winds were topping out at 155 mph.
As a Category 4, Michael is the strongest hurricane on record to hit that part of Florida.
It's also the strongest hurricane to directly hit the U.S. so far this year.
Last month, Hurricane Florence made landfall in North Carolina as a Category 1 storm.
Beyond Florida, forecasters predict Michael will bring hurricane-force winds and heavy rains across portions of Alabama and Georgia.
Residents in the Carolinas and southern Virginia could see up to 6 inches of rain later in the week.
It's also expected to bring massive power outages.
In preparation, officials in Florida, Alabama and Georgia all declared states of emergency, and about 375,000 people in Florida were ordered to evacuate. Flooding from Michael has already led to at least 13 deaths in Nicaragua, Honduras and El Salvador. Additional reporting from Newsy affiliate CNN .
