Barry, the second named storm of this year's Atlantic hurricane season, became a tropical depression by Sunday night, when it made landfall shortly before 11 p.m. ET. It made landfall over Mexico's east coast about 15 miles south-southeast of Tampico, according to the U.S. National Hurricane Center in Miami.

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.
