000 AXPZ20 KNHC 172206 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2130 UTC Mon Feb 17 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 2130 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 04N77W to 01N80W to 02N87W. The ITCZ begins near 04N91W then continues along 05N110W to 06N125W, then resumes near 07N134W and continues to 04N140W. Scattered moderate convection is from 04N to 09N between 102W and 113W, and from 06N to 17N between 117W and 128W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A high pressure ridge extends SE from the NE Pacific to just W of the Revillagigedo Islands. A weak pressure gradient over the region support NW gentle winds as shown by latest scatterometer data while the latest altimeter passes depict seas in the 4-7 ft range. Fluctuations in the pressure gradient between the ridge and a surface trough over the Gulf of California will support gentle to moderate NW winds across the gulf itself as well as the Baja California offshore waters through Sat. Fresh N winds in the Tehuantepec region will diminish to moderate tonight. Strong N gap winds will resume Wed morning and persist through Sun. Gale force winds are expected by Fri morning as a strong ridge builds in the Gulf of Mexico in the wake of a cold front. Gale conditions will prevail through Sat evening. Otherwise, light to gentle winds will prevail elsewhere this week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Strong to near gale force NE to E winds, highest overnights, will continue over and downwind of the Papagayo region through the week, with fresh offshore winds extending N to the Gulf of Fonseca. These winds are generating seas of 8 to 11 ft, which will also continue through the week. Fresh to strong N winds will also occur in and S of the Gulf of Panama through the week, with seas ranging from 7 to 8 ft. REMAINDER OF THE AREA... A middle-level low will continue to support a surface trough moving westward over the tropical waters W of 125W. Strong NE to E winds will prevail in the vicinity of the trough through Tue before decreasing. Latest altimeter passes indicate that these winds combined with mixed swell have produced seas of 8 to 13 ft. Seas will remain from 7 to 11 ft for much of the week due to general easterly trade winds and N swell propagating into the region. A weakening cold front will move into the NW forecast waters Wed, then dissipate by Thu. The front will bring fresh to locally strong NW winds N of 15N and W of 130W along with NW swell that will increase seas of 8 to 11 ft into late week. $$ Ramos
