1100 AM PDT Tue Jun 27 2023

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

Off the Southwestern Coast of Mexico (EP91):
Satellite wind data received within the past hour indicate that the 
low pressure system located a few hundred miles south-southwest of 
Manzanillo, Mexico, has become much better organized, and it 
appears that a tropical storm is forming.  Advisories will be 
initiated on this system at 2 PM PDT.  This system is expected to 
move westward at 5 to 10 mph during the next few days, away from the 
southwestern coast of Mexico.
* Formation chance through 48 hours...high...near 100 percent.
* Formation chance through 7 days...high...near 100 percent.

South of Southern Mexico and Central America:
A broad area of low pressure located a few hundred miles south of 
the coast of Guatemala is producing disorganized shower and 
thunderstorm activity.  Gradual development of this system is 
expected during the next several days, and a tropical depression is 
likely to form by the latter part of this week while it moves 
west-northwestward at 10 to 15 mph, roughly parallel to the southern 
and southwestern coasts of Mexico.  Interests along the southwestern 
coast of Mexico should monitor the progress of this system during 
the next several days.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 7 days...high...80 percent.
