Tropical Storm Raymond formed as a tropical depression on Saturday evening in the eastern Pacific Ocean.  As of Sunday morning, the storm is about 85 miles south of Acapulco, Mexico.

Tropical storm watches are in effect for the coast of southern Mexico, spanning from Acapulco westward to Lazaro Cardenas. The system is expected to produce  heavy rain for the next several days, which could cause life-threatening flash floods and mud slides along the coast.  

The areas affeted could be from Acapulco to Zihuatanejo and as far inland as Mexico City. Tropical storm-force winds are also possible within the watch area by late Monday.
