TAMPA, Fla. (AP) - All Isaac needs to do is come close to Tampa to bring a lot of problems to the Republican National Convention.
    
That's because even an average summer thunderstorm in this area can flood major roads.
    
When a tropical storm raked the Tampa Bay area a couple of months ago, thousands of homes and businesses lost power, tornadoes spun off and streets and bridges were closed.
    
It's still too early to say where Isaac will end up, but officials are closely watching the storm. They say they're ready to make any decisions about evacuations or cancellations as 70,000 delegates, journalists and protesters descend on the city.
    
The current forecast has Isaac likely strengthening into a hurricane Thursday and heading toward South Florida on Monday, the opening day of the convention.
