Florence rapidly intensified into a "potentially catastrophic" Category 4 storm Monday morning, but is not a direct threat to Florida.

Florence became a hurricane again Sunday morning, and is forecast to rapidly intensify into a major hurricane by Monday.

The tropical storm strengthened a bit Tuesday afternoon on its approach to the North-Central Gulf Coast, and now has maximum sustained winds up to 70 mph.

Tropical Storm Gordon formed Monday morning near Key Largo, Florida and is expected to bring heavy rain, gusty winds and possible tornadoes to portions of South Florida.

A tropical weather system is likely to produce heavy rain and gusty winds across South Florida on Labor Day, before moving into the Gulf of Mexico where it could intensify into a tropical storm.

A tropical wave will move across the peninsula this weekend, enhancing rainfall and potentially washing out holiday plans for many Floridians.

Multiple waves are forecast to emerge over the warming waters of the eastern Atlantic in the next few days, and one of them may approach the U.S. in about a week.

Fewer storms are likely this year in the tropical Atlantic, but the ones that do form could follow an unusual pattern.
