For the eastern North Pacific...east of 140 degrees west longitude:

Shower and thunderstorm activity associated with an elongated low pressure system near the southwest coast of Mexico has decreased since yesterday. However, environmental conditions still appear to be favorable for development, and a tropical depression is likely to form during the next couple of days as the system moves slowly northwestward or northward near the coast. Interests in Colima and Jalisco should monitor the progress of this system for any potential watches or warnings issued this weekend. Regardless of development, very heavy rains are expected over portions of southwestern Mexico during the next several days. * Formation chance through 48 hours...high...80 percent. * Formation chance through 5 days...high...90 percent.

A large area of disorganized showers and thunderstorms over the far eastern Pacific is associated with a broad area of low pressure. Some gradual development of this system is possible over the next few days before the system moves over Central America early next week. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...30 percent.
