This system is moving westward and is expected to cross into the Central Pacific basin on Monday. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...70 percent. Shower and thunderstorm activity associated with a tropical wave located several hundred miles south of the southern tip of the Baja California Peninsula has increased since this morning.

By Wednesday, strong upper-level winds will likely prevent further development. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. $$ Forecaster Zelinsky
