Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Sun Jun 28 2020

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

1. Showers and thunderstorms associated with a trough of low pressure 
located a few hundred miles west of the coast of southwestern Mexico 
have become better organized today. Although the system does not 
currently have a well-defined center, additional development is 
possible, and a tropical depression could form tonight or Monday as 
the system moves northwestward at about 15 mph. After that time, 
additional development will become unlikely as the disturbance moves 
over cooler waters. 
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.

2. An area of low pressure is likely to form a few hundred miles 
south-southwest of the Gulf of Tehuantepec by the middle of the 
week.  Environmental conditions are then forecast to be conducive 
for slow development while the system moves west-northwestward at 
10 to 15 mph well south of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
