Red Cross volunteers from Princeton journey to Florida

Red Cross volunteers from Princeton left for Florida this morning to help people prepare for Tropical Storm Isaac.

The Gulf Coast is getting ready for Wednesday's possible arrival of Isaac, which is expected to grow to a Category 2 hurricane.

The governors of Mississippi and Louisiana have declared states of emergency, and the Republican National Convention in Tampa, Fla., already postponed two days, is also getting ready for the storm.

Meanwhile, a new tropical storm warning has been issued for Louisiana's Gulf Coast. The warning covers the area from Morgan City, La., westward to Intracoastal City, La.
