Hurricane Isaac
Drivers along a stretch of the Florida Turnpike slow down after passing a sign warning of severe weather caused by Tropical Storm Isaac in Hialeah, Fla. Forecasters predicted Isaac would intensify into a Category 1 hurricane later Monday or Tuesday with top sustained winds of between 74 and 95 mph. The center of its projected path took Isaac directly toward New Orleans on Wednesday, but hurricane warnings extended across some 330 miles from Morgan City, La., to Destin, Fla. It could become the first hurricane to hit the Gulf Coast since 2008. (AP Photo/Wilfredo Lee)
