000 AXPZ20 KNHC 070306 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0305 UTC Fri Feb 7 2020 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0250 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 06N77W to 03N93W to 05N113W. The ITCZ extends from 05N113W to beyond 10N140W. Scattered moderate convection is noted within 60 nm of the trough between 86W and 89W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Earlier scatterometer data showed an area of fresh to strong northerly winds off the coast of Jalisco. Moderate to fresh winds were noted over the Baja California Sur offshore waters and the southern Gulf of California, south of a ridge axis that extends eastward across the northern waters. Elsewhere, gentle flow prevailed across the remaining forecast waters. Fresh to strong NW to N winds along the coast of Jalisco tonight will diminish by Fri morning. Seas will continue subsiding west of Baja California as northerly swell decays over the region. High pressure building in behind a cold front over the western Gulf of Mexico will generate strong N winds over the Gulf of Tehuantepec Fri. An approaching cold front will produce strong winds Sun over the northern Gulf of California, followed by increasing winds and building seas over the Baja California offshore waters Sun night into early next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Earlier scatterometer data revealed light to gentle winds across most of the forecast waters, except for moderate N winds noted over the Gulf of Panama. Wave heights remain less than 8 ft across the region. Fresh winds will prevail across the Papagayo region overnight, then pulse to strong speeds Fri night through early next week. Fresh winds will continue pulsing over the Gulf of Panama region through early next week. REMAINDER OF THE AREA... Surface high pressure dominates the waters north of 20N, with moderate to fresh NE trades west of 115W between this ridge and the ITCZ. Earlier altimeter data indicated seas were running 8-10 ft within this region, likely mixed in decaying N swell. A mid to upper-level low pressure system persists over the far NW portion, but no significant convection or marine conditions are associated with it. A cold front will approach the NW waters and stall west of 140W this weekend, resulting in strengthening winds and building seas north of the ITCZ and west of 135W. Elsewhere, expect increasing winds and building seas in NW to N swell over the northern waters Sun through early next week as a cold front moves southward into the region. $$ Reinhart
