Hurricane Irma is already the most powerful hurricane in recorded Atlantic Ocean history.
The Category 5 hurricane made landfall in the Caribbean with winds of up to 185 mph and is headed toward Florida.
So, how massive is this storm?
As of 4 p.m. ET Thursday, the hurricane was twice as wide as the Florida peninsula.
Take a look at the illustration below, which compares the size of Florida with the size of Hurricane Irma (satellite image by Weather Underground www.wunderground.com/wundermap).
Only three Category 5 hurricanes have ever hit the United States: Andrew (1992), Camille (1969) and an unnamed storm in 1935. As of now, Irma is expected to lose a little steam and become a Category 4 before it hits the United States.
