This NOAA satellite image taken Friday, August 3, 2012 at 10:45 AM EDT shows Tropical Storm Ernesto moves over the Windward Islands and into the Caribbean Sea. The system brought heavy rains and strong winds to the region as it remained at tropical storm strength with maximum sustained winds up to 50 mph. In the north, a tropical wave over the Bahamas has a low, 20% chance of tropical cyclone development over the weekend. However, the system will continue producing heavy rains and strong winds as it slowly moves westward into Florida and Cuba. (AP PHOTO/WEATHER UNDERGROUND)
