749 FZPN27 KNHC 012028 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 128 PM PDT Mon Sep 1 2025 Offshore Waters Forecast for the E Pacific within 250 nm of Mexico Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. PMZ001-020830- Synopsis for the E Pacific within 250 nm of Mexico 128 PM PDT Mon Sep 1 2025 .SYNOPSIS...Showers and thunderstorms associated with a tropical wave located less than 150 miles off the coast of southwestern Mexico are starting to become better organized. This system is expected to become a tropical depression by the middle of the week. This system is expected to move west- northwestward to northwestward at 10 to 15 mph off the coast of southwestern Mexico during the next couple of days, then could turn northward and approach the Baja California peninsula later this week. There is a high chance for tropical development. Regardless of development, expect increasing winds and seas over the waters off SW Mexico through the middle of the week then moving toward the Baja California peninsula later this week. 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 Tue before diminishing. $$ PMZ009-020830- Mexico Border S to 30N within 60 nm of shore- 128 PM PDT Mon Sep 1 2025 .TONIGHT...NW winds 10 to 15 kt.
