Irma became a category 5 hurricane just before 8 a.m. Tuesday. With winds at 175 mph and gusts measured at 215 mph.
The storm is still several hundred miles from the Leeward Islands. It is still too far out to determine impacts along the East Coast or the Gulf Coast, but it does look like there will be some interactions with land in the Greater Antilles, which could have an impact on the power and track of Irma over time.

Floridians took advantage of the Labor Day holiday to empty many store shelves of drinking water and other supplies in advance of Hurricane Irma, which could affect the state by the weekend. By mid-day Monday, many grocery stores across South Florida had been emptied of bottled water and stores were hoping to restock beginning Tuesday morning. Florida Gov. Rick Scott has urged Floridians to stay vigilant and monitor weather conditions.
Though it's still to early to know how Irma may impact the East Coast or the Carolinas, experts say now is the time to review your hurricane plan and be sure you are prepared for what's considered the peak time of hurricane season.
Behind Irma is a tropical wave off the west coast of Africa that has an 90 percent chance of development in the next five days. There's also a disturbance in the Gulf of Campeche that has a 60 percent chance of development.
The last hurricane to make landfall in the U.S. as a category 5 storm was Hurricane Andrew in 1992.
