000 AXPZ20 KNHC 282119 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Tue Mar 28 2017 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...INTERTROPICAL CONVERGENCE ZONE... The Intertropical Convergence Zone axis extends from 06N86W to 04N95W to 03N103W. Scattered moderate and isolated strong convection from 04N to 07N between 87W and 90W. Scattered moderate convection is withon 90 nm either side of axis between 90W and 100W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure north of the area extends a ridge southeast to near the Revillagigedo Islands. The pressure gradient between the ridge and lower pressure inland over Mexico is supporting fresh to strong NW winds west of Baja California Norte and moderate to fresh N-NW winds west of Baja California Sur. Gale force winds off the coast of southern California will continue to generate large long period NW swell that will propagate into the waters off Baja California and peak near 13 ft through Monday morning. The high pressure will remain nearly stationary over the next 48 hours. Light winds and seas prevail over the Gulf of California, except in the northern Gulf where northwest winds are 20-25 kt due to a locally tight pressure gradient. Seas will build to 4-7 ft with these winds. The winds will diminish tonight as the high weakens slightly. Light to gentle winds will prevail elsewhere through the week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gap winds are not expected to be very significant the next few days across Central America. Light to gentle winds and 3-5 ft seas are expected to prevail over the forecast waters the next several days. REMAINDER OF THE AREA... High pressure of 1031 mb located north of area near 34N131W dominates the north forecast waters. The pressure gradient between this high and the near-equatorial trough is supporting fresh to strong trades from roughly 10N-21N west of 125W. Seas over this area are in the 8-11 ft range in a mix of long period NW swell and NE wind waves. The aerial extent of the trades will diminish through Wednesday as the high pressure moves toward the SW and weakens slightly. Marine conditions over the forecast area will change little during the next 48 hours under the influence of this broad ridge. $$ GR
