Synopsis for the E Pacific within 250 nm of Mexico
950 AM PDT Mon Oct 19 2026

.SYNOPSIS...Tropical Storm Trudy is near 19.5N 108.5W at 8 AM 
PDT, and is moving west-southwest at 6 kt. Maximum sustained 
winds are 50 kt with gusts to 60 kt, and the minimum central 
pressure is 999 mb. Trudy will move to 19.5N 108.7W this evening,
become post-tropical and move to 19.5N 109.4W Tue morning, then
weaken to a remnant low near 19.9N 110.0W Tue evening. The
remnant low of Trudy will reach 20.3N 110.5W Wed morning, be just
northeast of the Revillagigedo Islands Wed evening, and 
dissipate Thu morning. High pressure settled over Mexico will
continue to funnel northerly gap winds of gale-force into teh
Gulf of Tehuantepec, southward to 11N, into Tue night, along with
rough to very rough seas. Winds will diminish to strong Wed, but
may increase to gale-force again Thu night and Fri. Showers and 
thunderstorms, associated with a trough of low pressure located 
several hundred miles south of Guatemala, remain disorganized. 
Environmental conditions appear conducive for development, and a 
tropical depression is expected to form around the middle of this
week as the system moves westward to west-northwestward at 5 to
10 kt, well to the south of the coast of southern Mexico. There 
is a medium chance of tropical formation of this low within 48 
hours and a high chance over the next 7 days.
