High pressure of 1031 mb centered NW of the area near 40N157W extends a ridge se to near 23N116W. The pressure gradient between the ridge and Hurricane Celia is supporting fresh trade winds north of 20N west of 126W. The pressure gradient between the ridge and a trough over the Gulf of California is supporting moderate northwest winds off the west coast of Baja California. Model guidance indicates this active period in tropical cyclone activity the past week or so is likely to continue. A low is expected to form several hundred miles south of southern Mexico by this weekend and may eventually intensify in the same general as Blas, Celia and TD 05E have during the past 5-10 days. A tropical wave will move across Central America over the next 24 hours. This will help for enhanced gap winds into the Gulf of Papagayo. Winds will reach near 25 kt during overnight hours over Wednesday morning and again Thursday morning with the added component of nocturnal drainage flow. $$ AL
