Hurricane Erin lashes Bahamas and Turks and Caicos with winds, rain, and flooding as forecasters track a new Atlantic tropical threat.

Erin is the fifth named storm to develop during the Atlantic hurricane season, which started just over two months ago. Last week, Tropical Storm Dexter formed in the western Atlantic but didn't pose a threat to land. In early July, Tropical Storm Chantal made landfall on the Carolina coast, bringing deadly flooding to the region.

FOX Weather Meteorologist Craig Herrera tracks the next system that has a medium chance of tropical development behind Hurricane Erin in the Atlantic Ocean's Main Development Region.
