Florida prepares for Isaac on eve of GOP convention

MIAMI (AP) -- Officials organized shelters and urged vacationers to leave the Florida Keys as Tropical Storm Isaac approached, though preparations farther north focused on getting ready for the Republican National Convention.

A hurricane warning had been issued for the Keys, though it was still a sunny day in Tampa. Forecast models show Isaac won't hit Tampa head-on, but the storm will still likely lash the city with rain and strong winds just as the convention ramps up. Protests were to start in full force on Sunday afternoon, and demonstrators have vowed that they will make their presence known rain or shine.

Isaac was forecast to hit the Keys late Sunday or early Monday, and it then could bring stormy conditions to Florida's west coast before moving to the Panhandle.
