FLORIDA (NBC) - Tropical Storm Isaac could pose a major threat to next week's Republican National Convention. It's expected to become a hurricane and hit Florida just as the convention is set to begin.
People in Puerto Rico loaded up on emergency supplies and boarded up their homes Thursday.
Isaac has been dumping heavy rains on the territory, leading to floods which forced the governor to declare a state of emergency.
In the Dominican Republic emergency workers are preparing for Isaac, too.
The storm is expected to reach hurricane strength Friday.
Isaac's progress has the attention of emergency teams in Florida.
Governor Rick Scott is holding twice daily meetings preparing for a worst case scenario, a hurricane strong enough to damage parts of the state and possibly put the Republican convention on hold.
"If there needs to be an evacuation, the decision will be made," Scott said.
The threat of weather isn't slowing preparations for the convention.
Organizers say they're ready, but even if Isaac doesn't directly hit Tampa area law enforcement says a hurricane anywhere in the state could reduce the number of officers available to help with security.
"If we move into a evacuation mode, you know, our resources change," notes Hillsborough County Sheriff David Gee.
Governor Scott says they have a contingency plan: The National Guard.
Four years ago Hurricane Gustav forced Republicans to cancel events at their convention in Minnesota.
