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

The National Hurricane Center is issuing advisories on Tropical Storm Greg, located several hundred miles southwest of the southern tip of the Baja California peninsula.

A broad area of low pressure centered several hundred miles south of the southern tip of the Baja California peninsula is producing disorganized showers and thunderstorms. Environmental conditions are forecast to be conducive for the formation of a tropical depression during the next couple of days before upper-level winds become unfavorable for development. This system is forecast to move westward to west-northwestward at around 10 mph through early next week. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...80 percent.

Showers and thunderstorms have become better organized in association with a tropical wave over the far eastern Pacific southwest of Central America. Environmental conditions are forecast to become increasingly favorable for development, and a tropical depression is likely to form later today or tomorrow while the system moves west-northwestward at 10 to 15 mph. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent.
