Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Wed Jun 16 2021
For the eastern North Pacific...east of 140 degrees west longitude:
1. A surface trough of low pressure is producing a large area of
disorganized showers and thunderstorms that extends several hundred
miles south of the coast of southern Mexico. Environmental
conditions appear conducive for development of this system, and a
tropical depression is likely to form late this week while moving
west-northwestward or northwestward at 5 to 10 mph, near the coast
of southwestern Mexico. Regardless of development, heavy rains are
likely over coastal sections of the Mexican states of Oaxaca,
Guerrero, Michoacan, Colima, and Jalisco during the next few days,
which could cause life-threatening flash floods and mud slides.
Interests in these areas should monitor the progress of this system
through the weekend.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...80 percent.
