A discontinuous monsoon trough extends from 09N78W to 09N98W, then resumes from 16N106W to 12N119W to 10N138W. Scattered moderate isolated strong convection from 06N to 11N between 83W and 94W. ...DISCUSSION... A moderate subtropical ridge extends SSE from a 1030 mb high centered near 43N143W across northern waters, roughly north of 20N and west of 123W. A moderate pressure gradient exists north of TD Ivette, and scatterometer data shows moderate to fresh trades north of 20N west of 128W. A surface trough extending across the northern Gulf of California and the Baja peninsula may be linking up with TS Javier to form a broad trough from the Mojave desert in southern California to near Manzanillo Mexico. The discontinuous monsoon trough is expected to re-form and shift southward over the next 24-36 hours as Javier is drawn northwestward into the trough across Baja California. This will allow winds and and seas to gradually diminish over waters south of 15N and east of 120W. $$ Mundell
