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.

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