A system near Mexico's Yucatan Peninsula has developed into the third tropical depression this year, forecasters at the National Hurricane Center in Miami said Monday.
The system is forecasted to drift west or west-southwest over the southern Bay of Campeche through the middle of the week.
Forecasters expect the storm to become Tropical Storm "Cristobal" this week.
Monday marked the official start of the Atlantic hurricane season, and forecasters are expecting a busier-than-normal season.
There have already been two named storms in May, and forecasters are expecting between 13 and 19 total named storms.
