Synopsis for the E Pacific within 250 nm of Mexico
1147 PM PDT Fri Sep 20 2024

.SYNOPSIS...Surface ridging will remain in place and fluctuate
into the weekend. Moderate to fresh NW winds will continue over
the Baja California offshore waters through late tonight, then
diminish to gentle to moderate speeds afterward into Wed night.
Ongoing moderate to fresh SW winds in the northern Gulf of
California will diminish to gentle speeds today and then prevail
through Wed night. An active monsoon trough will support moderate
to fresh W to SW winds across the outer SW Mexican offshore
waters through Mon. Looking ahead, an area of low pressure could
form well to the SW of the SW coast of Mexico this weekend.
Environmental conditions appear conducive for some slow
development of this system, and a tropical depression could form
during the next few days while it slowly moves generally N to NE.
Regardless of development, strong to near-gale force winds and
rough seas are forecast to affect the S and SW Mexican offshore
waters starting Mon night and continuing through the end of the
week.
