Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Thu Sep 21 2017

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

An area of disturbed weather is located near the southwestern coast of Mexico. Although shower and thunderstorm activity is showing some signs of organization, the system currently lacks a closed surface circulation. Environmental conditions are expected to be favorable for gradual development, and a tropical depression is likely to form near the southwest coast of Mexico during the next couple of days as the system drifts west-northwestward. Regardless of tropical cyclone formation, heavy rains are expected over portions of southwestern Mexico during the next several days. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent.
