Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Sat Sep 28 2019
For the eastern North Pacific...east of 140 degrees west longitude:
1. A large area of disturbed weather extends from Central America
westward along the southwest coast of Mexico. Although this system
does not appear to have a well-defined circulation at this time,
development is anticipated, and a tropical depression or tropical
storm will likely form later today or Sunday while the system moves
west-northwestward to northwestward at 10 to 15 mph, near the
southwestern coast of Mexico. Interests along that portion of the
coast should monitor the progress of this disturbance since tropical
storm watches or warnings could be required later today or Sunday.
Regardless of development, heavy rainfall, with the possibility of
flash flooding and mudslides, is expected to continue near the
southwestern coast of Mexico during the next few days. For
information on potential marine hazards, see High Seas forecasts
issued by the National Weather Service.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.
2. An area of low pressure is expected to form over the far
southwestern portion of the eastern North Pacific early next week.
Some gradual development is possible thereafter while the system
drifts slowly eastward or northeastward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
