Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Sat Aug 22 2020

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

1. An elongated area of low pressure located several hundred miles 
south-southwest of the southern tip of the Baja California peninsula 
continues to produce a large area of disorganized cloudiness and 
thunderstorms.  Conditions appear favorable for gradual development, 
and a tropical depression is likely to form during the early- 
to-middle part of next week while the system drifts a few 
hundred miles offshore the coast of southwestern Mexico.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...80 percent.

2. An area of low pressure is likely to form south of the Gulf of 
Tehuantepec during the next day or two.  A tropical depression is 
likely to form by the middle of next week while the system moves 
slowly northwestward or northward, near or parallel to the 
southwestern coast of Mexico. Regardless of development, areas of 
heavy rainfall and flash flooding are likely in southeastern Mexico 
and northern Central America during the next several days.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...high...70 percent.
