Hurricane Harvey just hit Houston, Texas a week or so ago, but now another Hurricane called Irma is gaining speed out in the Caribbean and heading for the East coast. It's already a Category 4 or 5 storm, according to weather reports.
Weatherman Al Roker said that if this hurricane makes landfall, then this will be the first time in history that a Category 4 or 5 storm has happened right after another one in that same category has ended.
