Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Sun Aug 23 2020

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

1. Showers and thunderstorms have decreased this evening in 
association with a broad area of low pressure located several 
hundred miles south of the southern tip of the Baja California 
peninsula.  Environmental conditions still appear conducive, 
however, for further development, and a tropical depression is 
expected to form during the next couple of days while the system 
meanders or drifts northward a few hundred miles offshore of the 
coast of southwestern Mexico. 
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

2. A small low pressure area located a couple of hundred miles 
south-southwest of the Gulf of Tehuantepec has changed little during 
the past several hours while producing only limited showers and 
thunderstorms.  Conditions appear conducive for additional 
development of this system, and a tropical depression is likely to 
form within the next couple of days while it moves slowly 
northwestward, 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...high...70 percent.
* Formation chance through 5 days...high...90 percent.

of the southern tip of the Baja California peninsula, see High Seas
