Irma has quickly become one of the most powerful Atlantic Ocean hurricanes ever recorded, with wind speeds of 185 miles per hour. As this monster churns through the Caribbean and heads toward Florida, here's the lowdown.

At least five people were killed and eight others were injured in a shooting Friday afternoon at Fort Lauderdale-Hollywood International Airport in Florida, according to the Broward County Sheriff's Office. The sheriff's office tweeted that "one subject" was in custody and that the injured had been taken to a local hospital. The mayor of Broward County, Barbara Sharief, also told CNN that a suspect had been taken into custody.
