Synopsis for the E Pacific within 250 nm of Mexico
833 PM PDT Mon Sep 1 2025

.SYNOPSIS...Newly formed Tropical Depression Twelve-E is located
near 17.2N 105.4W, moving west-northwest at 12 kt. Maximum
sustained winds are 30 kt with gusts to 40 kt. Estimated minimum
central pressure is 1007 mb. Twelve-E is expected to move west-
northwestward to northwestward at 10 to 15 kt, and gradually
intensify, remaining off the coast of southwestern Mexico during
the next couple of days, and then is expected to turn northward
and approach Baja California Sur Thu night through Fri night.
Twelve-E is expected to reach near 18.3N 107W as a tropical
storm Tue morning, reach near 21N 111W Wed morning, near 23N
113.3W Thu morning, and near 24N 113.7W late Thu afternoon.
Elsewhere, high pressure will remain centered NW of the area
through mid- week, with an associated ridge across the Baja
California waters, and will support moderate NW to N winds
across the Baja waters through Tue before diminishing. Fresh to
strong southerly winds are expected to develop inside the
southern Gulf of California Thu as Twelve-E approaches the
Pacific coast.
