Forecasters are watching an area around Florida's Gulf and Atlantic coasts for tropical development during the July 4 weekend.

Tropical Storm Flossie continued to gain steam off Mexico's southwestern Pacific coast on Monday afternoon and was projected to turn into a hurricane overnight. Meanwhile, the remnants of what was Tropical Storm Barry dumped rain on eastern Mexico.

Heavy rainfall, strong winds, and localized flooding are concerns for eastern Mexico, particularly with the expectation of up to 45 mph winds at landfall.
