000 AXPZ20 KNHC 301545 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1545 UTC Wed Nov 30 2016 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from low pressure near 10N75W to 08N88W to low pressure near 10N98W to 12N105W to 08N112W. The intertropical convergence zone axis extends from 08N112W to 09N120W, then resumes from 10N123W to 10N140W. Scattered moderate convection is within 120 nm in the southeast quadrant of the low near 10N98W. Scattered moderate and isolated strong convection is within 300 nm northwest of a line from 12N125W to 06N130W. A 1010 mb surface low is near 14N108W with scattered moderate and isolated strong convection within 210 nm in the east quadrant. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Northwest swell prevails over the offshore waters off the western coast of the Baja California norte where seas are in the 8 to 12 ft range. Seas have subsided below 8 ft just off the coast of Baja California Sur with seas in the 6 to 7 ft range. Elsewhere over the remainder of the offshore waters off the coast Mexico, seas are in the 4 to 7 ft range, while seas of 2 to 4 ft are noted over the Gulf of California where moderate to locally fresh northwest flow prevails. Continued pulses of northwesterly swell will push across the area through the remainder of the week and into the upcoming weekend. High pressure will build over the Great Basin of the United States through the weeks end. This will bring fresh to near gale force northerly winds over the Gulf of California Friday night through early Sunday as a very tight pressure gradient sets up across the region. A cold front moving across the Gulf of Mexico will bring the next Gulf of Tehuantepec gap wind event early Thursday morning. A progressive pattern will help winds to veer rapidly over the southwest Gulf of Mexico and keep this gap wind event brief. Winds will reach fresh to strong Thursday morning, diminishing in the afternoon hours. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle winds and seas in the 3 to 5 ft range are noted north of 10N, with moderate to locally fresh southwest flow and combined seas of 3 to 5 ft south of 10N. Winds will occasionally pulse to moderate to fresh offshore of the Gulf of Papagayo during the overnight hours. REMAINDER OF THE AREA... High pressure of 1033 mb is centered northwest of the area near 38N142W. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting fresh to locally strong trades north of the ITCZ to near 29N and west of 125W. Combined seas of 8 to 13 ft prevail over this area with the highest seas near 30N124W. Continued pulses of northwesterly swell will maintain seas of 8 ft or greater over much of the area north of the ITCZ through the remainder of the week and into the weekend. $$ LEWITSKY
