Hurricane Irma is gaining strength as it heads into the Caribbean. The latest model from the American Global Forecasting System shows it's likely to hit the U.S. on Sunday or Monday between Florida and the Carolinas.
That forecast then has Irma marching up the East Coast through the mid-Atlantic states and possibly into the Northeast.
This hurricane, which some are now calling the most powerful in a decade, comes just one week after Hurricane Harvey plowed into South Texas, killing at least 60 people and causing billions of dollars in damage.
Forecaster Dan Leonard of the IBM-owned Weather Co. said, "Irma is already in a rare class of storms with 180 mph winds." Leonard, sometimes known as "Wall Street's weatherman" because he advises many hedge funds and commodity traders, said he believes Irma could be a real monster, causing death and severe destruction.
