Hurricane Irma is now a Category 1 storm as it makes its way up the west coast of Florida, following its second landfall in Southern Florida on Sunday. NASA and the National Oceanic and Atmospheric Administration (NOAA) are providing satellite imagery to the National Hurricane Center to aid forecasts about Irma's potential for destruction on the U.S. mainland after battering the Caribbean and Atlantic Ocean island nations in the path of the storm. They are also tracking Hurricane Jose, a Category 4 storm behind Irma, and the now-Tropical Storm Katia in the Gulf of Mexico. [Hurricane Irma in Photos: Views of the Monster Storm from Space]
