Well East-southeast of the Hawaiian Islands (EP90): Shower and thunderstorm activity continues in association with an area of low pressure located well east-southeast of Hawaii. Environmental conditions are expected to be conducive for development and a tropical depression is likely to form during the next couple of days. The disturbance is forecast to meander slowly northward or northeastward during the next couple of days or so, before accelerating west-northwestward into the Central Pacific basin by the latter portion of the week. Information on this system's development can also be found in the Tropical Weather Outlook for the Central Pacific basin. * Formation chance through 48 hours...high...70 percent. * Formation chance through 7 days...high...80 percent. 2. Western Portion of the East Pacific: A broad area of shower and thunderstorm activity is located well west-southwest of the southern tip of the Baja California peninsula. This system is forecast to move slowly toward the northwest for the next few days, and interactions with either EP90 to its west or Gilma to its east could limit the potential for formation. Regardless, a tropical depression could form within the next few days. Further development after that time will be unlikely. * Formation chance through 48 hours...low...20 percent. * Formation chance through 7 days...medium...40 percent. 3. Eastern and Central Portion of the East Pacific: An area of low pressure is expected to form well to the south of the southwestern coast of Mexico by the end of this week. Environmental conditions could become conducive for some slow development of this system thereafter as it moves slowly west-northwestward. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 7 days...low...30 percent.
