A wet, messy storm in Mexico’s Bay of Campeche strengthened early Wednesday to a tropical depression, a warning that the Atlantic hurricane season is still open for business. The system, a remnant of Tropical Storm Trudy that triggered fatal mudslides in southern Mexico last week, is expected to become a tropical storm Wednesday as it heads toward the Yucatan Peninsula with winds of about 35 mph, the National Hurricane Center said. But forecasters expect a cold front moving south to keep it from growing as the storm nears the U.S. coast. Still, South Florida could get hit with heavy rain and possible flooding later this week.
