Synopsis for the E Pacific within 250 nm of Mexico
222 AM PDT Tue Sep 2 2025

.SYNOPSIS...Tropical Depression Twelve-E is located near 17.6N
106.8W at 02/0900 UTC, moving west-northwest at 13 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 through Fri night. Twelve-E
is expected to reach near 18.6N 108.5W as a tropical storm
midday Tue, reach near 20.1N 110.5W midnight Tue, near 21.2N
112.3W midday Wed, near 23.2N 114.2W midday Thu, then move
northward to near 24.2N 114.3W midnight Thu, and near 26.3N
113.5W midnight Fri. Elsewhere, high pressure will remain
centered NW of the area through mid- week, with an associated
ridge across the Baja California waters. The pressure gradient
between this area of high pressure and a trough over the Gulf of
California will support moderate NW to N winds across the Baja
waters through Wed before diminishing. Fresh to strong southerly
winds are expected to develop inside the southern Gulf of
California Thu as Twelve-E approaches the Baja Pacific coast.
