Synopsis for the E Pacific within 250 nm of Mexico
232 PM PDT Wed Jul 2 2025

.SYNOPSIS...Hurricane Flossie is centered near 19.5N 109.8W at
2100 UTC, and moving northwest at 8 kt. Maximum sustained winds
are 85 kt with gusts to 105 kt, and the minimum central pressure
is 974 mb. Flossie is expected to continue moving NW and
gradually weaken through tonight, reaching near 20.1N 110.8W
around midnight, near 21.1N 112.3W midday Thu as a tropical
storm, then become a 40 kt post-tropical low near 22.1N 113.8W
around midnight Thu, then reach near 23.1N 115.4W Fri afternoon
as a remnant low. Elsewhere, large swell generated from Flossie
will impact the waters from Colima and Jalisco to the central
Gulf of California and Baja Sur to Punta Eugenia through late
Thu. Expect fresh to strong SE winds through the Gulf of
California through Thu morning. Looking ahead, fresh to strong E
to SE winds and rough seas are possible off Oaxaca and Guerrero
Thu night through Sat as an area of low pressure moves to the
W-NW and offshore of the coast of southern Mexico. This area of
low pressure is forecast to develop several hundred miles
offshore of southwestern Mexico in a few days. Environmental
conditions appear conducive for some gradual development of this
system thereafter, and a tropical depression could form over the
weekend or early next week while it moves generally west-
northwestward.
