South of Southern Mexico (EP90): A large and persistent area of showers and thunderstorms remains disorganized near and to the west of a small area of low pressure located just offshore of the coast of southern Mexico. Environmental conditions appear conducive for gradual development over the next few days, and a tropical depression is likely to form late this week if the system remains over water. The disturbance is forecast to move west-northwestward at 10 to 15 mph, roughly parallel to the coast of southern and southwestern Mexico, and interests there should monitor its progress. Regardless of development, the disturbance is expected to produce periods of heavy rainfall along portions of the southern and southwestern coasts of Mexico through the end of the week, which could lead to localized flooding. * Formation chance through 48 hours...high...70 percent. * Formation chance through 7 days...high...80 percent.
