Three Atlantic hurricanes may hit land on the same day this weekend

Right now, three hurricanes are spinning in the Atlantic Ocean, an unusual event that hasn't happened since 2010. Even stranger, each of them is expected to hit land on the same day: Saturday. 
First, there's record-shattering Hurricane Irma, of course, which devastated parts of the northern Leeward Islands, as well as the Caribbean, and poses a dire threat to the Southeast. It is forecast to pass over or very close to South Florida on Saturday night into Sunday as a Category 4 or 5 storm.
