This NOAA satellite image taken Wednesday, August 22, 2012 at 01:45 PM EDT shows Tropical Storm Isaac moves over the Lesser Antilles, bringing heavy rains and strong winds to the region. This system has maximum sustained winds up to 45 mph and it continues moving westward at 21 mph. Isaac is expected to strengthen as it moves over the northeastern Caribbean Sea over the next few days. To the north, a frontal boundary lingers over Florida and the Gulf of Mexico, producing more heavy rains and strong winds. (AP PHOTO/WEATHER UNDERGROUND) less
