Isaac Expected to Become Hurricane

Tropical Storm Isaac is emerging from the Haiti coast and forecasters have upped the ante, issuing hurricane warnings and watches through the parts of Florida.

Warnings have been issued for the Florida Keys, the west Coast of Florida from Bonita Beach southward and for Florida Bay. The watch area currently includes Florida's east coast from Golden Beach southward. The Bahamas government has issued a hurricane watch for Andros Island.

Forecasters expect Isaac to move over Cuba today and become a hurricane tomorrow.

The storm brought heavy rain to Haiti and the Dominican Republic.

Organizers of next week's Republican National Convention in Tampa say they are monitoring the storm. Some 70,000 delegates, journalists and protesters are expected, and Florida Gov. Rick Scott said there are no plans to cancel the convention.
