1100 PM PDT Thu Oct 21 2021

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

1. Showers and thunderstorms associated with a low pressure area 
located about 250 miles south of Acapulco, Mexico, continue to show 
signs of organization, but recent satellite wind data indicate that 
the low does not yet have a closed surface wind circulation.  
Environmental conditions are expected to be conducive for additional 
development, and a tropical depression or tropical storm is expected 
to form over the next day or so while moving slowly 
west-northwestward or northwestward just offshore the southern coast 
of Mexico.  Interests along the southern and southwestern coast of 
Mexico should monitor the progress of this system during the next 
few days, and additional information, including gale warnings, can 
be found in High Seas Forecasts issued by the National Weather 
Service.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

High Seas Forecasts issued by the National Weather Service can be 
found under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on
