Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Tue Jun 23 2020

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

1. A nearly stationary area of low pressure is located about 1600 miles 
southwest of the southern tip of the Baja California peninsula. 
Although this disturbance has a well-defined circulation, it is 
producing only limited shower activity.  Environmental conditions 
are expected to support the redevelopment of thunderstorms and the 
system is likely to become a tropical depression during the next few 
days while it moves slowly westward.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.

2. An elongated area of low pressure located several hundred miles 
southwest of the southern tip of the Baja California peninsula 
continues to produce a wide area of disorganized showers and a few 
thunderstorms.  This system could become a tropical depression 
during the next day or two before it moves over cooler waters that 
will inhibit further development.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.

3. Disorganized showers and thunderstorms located a few hundred miles 
south-southwest of the Gulf of Tehuantepec are associated with a 
tropical wave.  Environmental conditions are forecast to be 
favorable for development, and the system is likely to become a 
tropical depression in a few days while it moves west-northwestward 
parallel to the coast of Mexico.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...80 percent.

4. Another area of low pressure is forecast to form south of the Gulf 
of Tehuantepec by late this week. Gradual development of this system 
will be possible over the weekend as it moves west-northwestward 
parallel to the coast of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.
