000 AXPZ20 KNHC 160402 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Wed Mar 16 2022 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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 0345 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The ITCZ extends from 03N111W to 04N122W to 03N131W and to beyond 04N140W. No significant convection is noted. OFFSHORE WATERS WITHIN 250 NM OF MEXICO High pressure NW of the region is anchored by a 1028 mb high near 30N130W. A ridge extends from this high It , and extends a ridge SE across over the offshore waters to 16N107W. The associated pressure gradient is producing moderate to locally fresh NW to N winds along the Baja California Norte offshore waters, with wave heights of 7-10 ft in mixed N and NW swell. Seas are highest across the outer waters. Gentle to moderate NW to N winds are seen elsewhere offshore of Baja south of Punta Eugenia, where wave heights are 5-8 ft. Inside the Gulf of California, gentle to moderate NNW winds prevail, with wave heights of 2-4 ft. Light to gentle variable winds are elsewhere along and near the south and southwestern Mexican offshore waters to Puerto Angel, where wave heights of 4-5 ft continue in NW swell. High pressure building southward across eastern Mexico and the western Gulf of Mexico has induced strong to near- gale force north winds gap winds across the Gulf of Tehuantepec during the past few hours. Since then, wave heights there have risen to the 8-10 ft range. Moderate to fresh northerly winds will prevail off Baja California through Thu as the ridge remains in place the next couple of days. NW swell over the offshore waters of Baja California Norte today will reach the waters offshore of Cabo San Lucas late Wed and Wed night. The strong to near gale- force Gulf of Tehuantepec gap winds will spread offshore to near 13N by late tonight. These winds will diminish to strong speeds Wed morning into early Wed afternoon, then diminish to fresh speeds during the rest of the afternoon and become west to northwest at moderate speeds Wed night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh northeast to east gap winds prevail across the Papagayo region producing wave heights in the range of 5-7 ft. Moderate north to northeast winds are in the Gulf of Panama along with wave heights of 3-5 ft in new SW swell. Light to gentle variable winds are elsewhere along with wave heights of 3-5 ft due to the arrival of small to moderate S to SW swell. Gentle winds will continue through most of the forecast period, except for the Papagayo region where the fresh to strong winds will continue to pulse through Wed night. Moderate northerly winds will also pulse in the Gulf of Panama through tonight. REMAINDER OF THE AREA High pressure of 1028 mb is centered near 30N130W. The associated surface ridge extends southeastward to just SE of the Revillagigedo Islands. The associated gradient between this ridge and relatively lower pressure to its south continues to sustain moderate to fresh northeast to east winds between the ITCZ and 24N and west of about 118W. Seas are 8-10 ft in NW swell across this area. Lingering moisture associated to a large mid to upper- level low that is west of the area near 13N144W covers the waters east of 140W to near 118W and from about 12N to 20N. Small pockets of scattered moderate convection are possible within this area of moisture, mainly west of 129W. Current trends of this activity is that of decreasing. Winds over the western part of the area from 08N to 20N and west of 127W have diminished to mainly fresh speeds. Wave heights within this area are in the range of 8-11 ft due to a NW swell, except from mixed NE and NW swell south of 17N. The northwest swell component is from a large set of NW swell that recently entered the northern forecast waters. This swell set will propagate southeastward through most of the region going into Thu. The aforementioned small pockets of moderate convection will occur intermittently between the ITCZ and 20N and to the west of about 130W through Wed night. $$ Aguirre
