000 AXPZ20 KNHC 222040 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2020 UTC Sun Mar 22 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 1800 UTC surface analysis and satellite imagery through 2000 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The ITCZ extends from 05N87W to 03N107W to 04N122W to beyond 03N140W. Scattered moderate to isolated strong convection is located from 01N to 13N between 115W and 135W. Scattered moderate convection is located from 02N to 05N between 96W and 106W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A 1021 mb high pressure center near 28N119W will weaken Mon and dissipate by Mon night. This high will create moderate to locally fresh N winds to the N of 20N through early this week. S of 20N light winds prevail. A surge of high pressure pushing into the waters well west of Baja California Norte is causing a cold front to develop from around 30N122W and SW. This front will maintain strength overnight, then begin to dissipate as it reaches the W coast of Baja California Norte Mon. Behind the front, the high pressure building into the area well produce fresh to locally strong NW to W winds off Baja California Sur and in the southern Gulf of California Mon night into late week, with seas of 5 to 7 ft in open waters. Fresh N gap winds in the Gulf of Tehuantepec this afternoon will pulse to strong tonight, then diminish thereafter into at least late week. Seas of 7 to 9 ft can be expected. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Strong high pressure over the northern Caribbean will maintain fresh to strong NE to E winds, highest during the late nights and early mornings, over the Gulf of Papagayo region through early Tue. Peaks seas of 8 to 9 ft can be expected to develop downstream each early morning. As the high pressure weakens toward mid-week, winds will decrease to moderate to fresh and seas will fall below 8 ft. Expect gentle to moderate winds to remain elsewhere across the offshore waters into mid week, except for the Gulf of Panama, where some locally fresh winds may pulse each night. REMAINDER OF THE AREA... A surge of high pressure moving into the NW waters has re- energized the trough of low pressure into a developing cold front extending from 30N122W to 20N133W. This front will maintain its strength tonight, the dissipate Mon from near 30N117W to 24N124W. Moderate to fresh NW winds can be expected tonight behind the front, then winds will decrease to gentle to moderate on Mon. Seas of up to 12F N of 27N and W of 135 will diminish this evening, with seas in this area falling below 8 ft late Mon. Farther S, a surface trough just N of the ITCZ along 132W will meander between 130W and 140W over the next few days, bringing scattered to numerous convection along it. As high pressure builds into northern areas for the first half of this week, the pressure gradient between it and the ITCZ will increase, leading to higher winds and seas. Moderate to strong trade winds can be expected, with seas of 8 to 11 ft in combined trade winds swell and NW swell. $$ KONARIK
