Tropical storm Isaac is in the Atlantic near the Island of Guadalupe. It could head to Tampa Bay by Monday as a hurricane.
Dennis Feltgen, spokesman for the National Hurricane Center in Miami, says Isaac may not be a tropical storm for long...
"It is moving into an area which is favorable for strengthening and we would expect Isaac to become a hurricane probably sometime late Thursday or on Friday," he says.
Feltgen says it's still too early to tell if Isaac will hit Tampa Bay early next week- the start of the Republican National Convention.
"Central and South Florida is in the fifth day of the forecast cone which of course has a margin of error of about 236 miles in any direction," he says.
If Isaac does turn into a hurricane and heads to Tampa, Hillsborough County Emergency Management would make the call whether or not to evacuate. RNC Host Committee chairman Ken Jones says they also have contingency plans in place.
