.INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
MONSOON TROUGH EXTENDS FROM 05N77W TO 05N83W TO 04N91W WHERE IT
TRANSITIONS TO THE ITCZ. ITCZ THEN EXTENDS ALONG 06N102W TO
08N109W TO 08N118W. ITCZ RESUMES W OF A SURFACE TROUGH FROM
07N122W AND CONTINUES PAST 06N140W. SCATTERED MODERATE ISOLATED
STRONG CONVECTION IS FROM 02N TO 13N W OF 124W.
A 1032 MB HIGH PRESSURE SYSTEM LOCATED NW OF THE AREA EXTENDS A
RIDGE SOUTHEAST TO THE REVILLAGIGEDO ISLANDS. THE PRESSURE
GRADIENT BETWEEN THE HIGH PRESSURE AND TROUGHING ACROSS THE GULF
OF CALIFORNIA IS SUPPORTING GENTLE TO MODERATE NORTHWEST WINDS
ACROSS THE ENTIRE GULF OF CALIFORNIA. SEAS WITH THESE WINDS
PRESENTLY HAVE A MAXIMUM OF AROUND 3 FT. MODEL GUIDANCE SUGGESTS
THAT THE PRESSURE GRADIENT WILL TIGHTEN EARLY THU MORNING AS A
STRONG RIDGE BUILDS OVER THE STATE OF IDAHO. THIS WILL LEAD TO
FRESH TO STRONG WINDS OVER ALMOST ALL OF THE GULF OF CALIFORNIA
THROUGH FRI MORNING.
