Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Thu Jun 17 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 disturbance, and
a tropical depression is likely to form during the next couple of
days while the system moves 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 mudslides. Interests in these areas should monitor the
progress of this system through the weekend.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.
