Tropical Storm Barry was nearing the eastern Gulf Coast of Mexico on Sunday evening, and was expected to bring heavy rains and flash flooding to the North American nation over the next few days.

Satellite images show that the storm should weaken as it nears the coast sometime overnight Sunday or early Monday. Even though the storm will weaken as it approaches land, it will still bring tropical storm conditions near the coast throughout Monday.

Barry was a tropical storm in the Bay of Campeche Sunday afternoon Eastern time, the National Hurricane Center said in its latest advisory. The tropical storm had sustained wind speeds of 45 miles per hour.
