1100 PM PDT Thu Jul 29 2021

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

1. An area of low pressure located about 650 miles southwest of the 
coast of southwestern Mexico continues to produce showers and 
thunderstorms.  This system is gradually becoming better organized, 
but the latest satellite wind data shows that the low lacks a 
well-defined center. Environmental conditions are conducive for 
further development, and a tropical depression or tropical storm is 
expected to form by Saturday while the system moves west- 
northwestward at 10 to 15 mph. For more information on this system, 
please see High Seas forecasts issued by the NOAA Tropical Analysis 
and Forecast Branch.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

2. Showers and thunderstorms have increased in association with an 
area of low pressure located about 1200 miles southwest of the 
southern tip of the Baja California peninsula.  Upper-level winds 
are expected to become more conducive for development during the 
next couple of days, and a tropical depression is expected to form 
over the weekend while the system moves generally westward at 5 to 
10 mph.
* Formation chance through 48 hours...high...80 percent. 
* Formation chance through 5 days...high...90 percent.

3. An area of disturbed weather continues several hundred miles 
south-southwest of the Gulf of Tehuantepec.  Additional gradual 
development is expected during the next several days, and the 
system could become a tropical depression early next week while it 
moves west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...30 percent. 
* Formation chance through 5 days...medium...50 percent.
