000 AXPZ20 KNHC 060916 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 835 UTC Tue Mar 6 2018 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 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The ITCZ axis extends from 01N110W to 01N120W to 05N130W to beyond 07N140W. Widely scattered moderate convection is from 04N to 08N between 127W and 135W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The NW swell from a recent cold front continues to propagate southward through the offshore waters of Baja California Sur as it decays tonight. Weak high pressure over the NE Pacific and along the coasts of California and Oregon will reorganize to the south along about 30N tonight through Tue to produce moderate N to NNW winds across the offshore waters of Baja California, continuing through Wed. The high pressure will strengthen Wed night and Thu and act to freshen winds across the waters during the latter part of the week. Gulf of California: The pressure gradient inside the Gulf is producing fresh northerly winds to the N of 24N across the Gulf. These winds to near 25 kt will continue tonight, with seas expected to increase to 6ft across central portions. Winds will then begin to diminish Tue as a high center reorganizes along 30N. Gulf of Tehuantepec: A weak pressure gradient across the Tehuantpec region is allowing local wind flow to be dominated with land-sea interaction, with light onshore flow expected the remainder of the afternoon and on Tue, and a moderate land breeze at night. A cold front moving across the Gulf of Mexico Tue and Wed will induce strong northerly winds across Tehuantepec on Wed. Winds are expected to increase to gale force on Wed night and continue through around midday on Thu. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... The Fuego Volcano located near 14.5N 90.9W over southern Guatemala is venting light amounts of ash, with the associated ash cloud drifting W and remaining over land. Recent satellite imagery suggests no significant ash clouds have developed tonight. Local interests are urged to closely follow volcanic activity in this area. Moderate N to NE winds across the SW Caribbean are producing fresh to strong gap winds across the Gulf of Papagayo. Winds are expected to briefly pulse to near 30 kt on Wed night, with seas building to 9 ft. Subsequent days will usher 25 kt winds during late night and early morning hours, with seas peaking to 8 ft. Across the Gulf of Panama, fresh northerly winds will pulse to strong during the overnight and early morning hours through Wed. Seas are expected to range in the 7 to 9 ft range. Elsewhere, expect gentle to moderate winds and 4-7 ft seas through the next couple of days. REMAINDER OF THE AREA... An extensive area of NW to N swell is mixing across the waters W of 120W with easterly tradewind waves to produce seas in the range of 8 to 11 ft, covering an area from 05N TO 20N to the W of 120W. This NW swell will gradually fade over the next 24 to 48 hours, and significantly reduce the area of 8 ft and higher seas across this zone. The next cold front has just reached the far NW corner of the forecast area near 30N140W. NW swell generated by an accompanying low pressure system to the NW is moving into the area slightly ahead of the front. W of front over the NW corner W to NW 15 to 20 kt are expected with 8 to 13 ft NW swell. This front will propagate ESE over the next 48 hours and is expected to reach from 30N129W TO 21N133W by Wed night where it will begin to dissipate. $$ Formosa
