000 AXPZ20 KNHC 120951 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 0405 UTC Sat May 12 2018 Corrected Offshore waters within 250 nm of Mexico section 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 0000 UTC surface analysis and satellite imagery through 0330 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 09N83W to 09N100W to 09N111W to 09.5N125W. Latest scatterometer data indicated that the intertropical convergence zone (ITCZ) begins at 09N132W and continues to 08N140W. Scattered moderate to strong convection is within 180 nm south of the axis between 103W and 106W, from 10N to 14N between 110W and 114W, and within 120 south of the axis between 114W and 118W. Scattered moderate isolated strong convection is within 240 nm south of the axis between 108W and 114W, and within 120 nm north of the axis between 101W and 104W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Deepening low pressure over the southwest United States is creating a fairly tight pressure gradient across the northern Gulf of California and Baja California Norte. Winds have increased from S to SW in direction to near gale force, with seas to 9 ft. These winds will slowly diminish to strong winds by early Sun, with seas to 8 ft. Winds diminish to moderate to fresh on Sun afternoon, with seas less than 8 ft. Meanwhile, gentle to moderate winds will dominate the offshore waters W of Baja California with seas of 6-9 ft in long period NW swell. These conditions wil continue through Sun afternoon. Seas will subside to 5-7 ft by early Sun evening. Farther south in the Gulf of Tehuantepec, mainly light to gentle winds are expected through the weekend, with seas of 4-6 ft in long period southerly swell. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gulf of Papagayo: Moderate to fresh NE-E winds are expected across the Gulf of Papagayo through tonight, then diminish thereafter. Seas are forecast to be in the 4-6 ft range. Gulf of Panama: Gentle to occasionally moderate southwest winds are forecast during the next several days, with seas of 4 to 6 ft in long period southerly swell. REMAINDER OF THE AREA... A ridge extends from 1032 mb high pressure located north of the area near 43N136W to the Revillagigedo Islands. Low pressure, remnants of Tropical Depression One-E, is located near 13N130W 1008 mb. Scattered moderate isolated strong convection is observed well removed to the northeast of the remnant low within 30 nm of 14N128.5W. Isolated showers and thunderstorms and are seen from 13N to 15N between 130W and 131W. The pressure gradient between the ridge and the remnant low is supporting generally moderate to locally fresh trade winds over the region west of 130W. Northerly swell in excess of 8 ft will continue to propagate south of 32N reaching as far south as 22N by early Sun afternoon before decaying below 8 ft by Sun night. Seas will reach 8 ft south of the monsoon trough between 100W and 120W starting today due to the fresh SW flow and southerly, cross- equatorial swell. Seas will subside below 8 ft by late Sun. $$ Aguirre
