000 AXPZ20 KNHC 262120 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sun Mar 26 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 ITCZ extends from 03N121W to 01N140W. Scattered moderate convection is noted within 120 nm north of the ITCZ between 127W and 135W. Similar convection is from 02N to 05N between 87W AND 92W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure of 1028 mb centered near 33N148W extends a ridge southeast to near the Revillagigedo Islands. The pressure gradient between the ridge and a trough of low pressure over the Gulf of California is supporting moderate to fresh winds west of the Baja California peninsula with seas in the 6-8 ft range. Light to gentle winds with seas 2 ft or less prevails over the Gulf of California. Light winds with seas in the 4-6 ft range prevails elsewhere. The area of high pressure will further building early next week, which will tighten the pressure gradient and strengthen winds off the coast of Baja California Norte. Northwesterly swell will propagate into the waters off Baja California Norte Monday, and peak near 13 ft early Tuesday morning. Winds will strengthen over the northern Gulf of California early Tuesday as the pressure gradient tightens before diminishing Wednesday as the area of high pressure weakens slightly and loosens the pressure gradient. Elsewhere, winds will generally be light to gentle with seas in the 4-6 ft range through the middle of next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh NE winds are expected over the Gulf of Papagayo during the late night hours tonight into the early morning hours Monday morning. Light to gentle winds and seas of 3-5 ft are expected elsewhere the next several days. REMAINDER OF THE AREA... High pressure prevails over the northern waters. The pressure gradient between this area of high pressure and the equatorial trough is supporting fresh to strong trades over the tradewind belt. Seas over this area are in the 8-10 ft range in a mix of long period NW swell and NE wind waves. This area of trades will persist through Monday, but the aerial extent of the trades will increase by Monday night as a high pressure located just north the area strengthens. At that time, the GFS computer model shows a high pressure of 1033 mb located near 35N131W. $$ GR
