518 AXPZ20 KNHC 160229 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 038 UTC Thu Jul 16 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 0000 UTC surface analysis and satellite imagery through 0230 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 94W north of 03N, moving westward at 10-15 kt. Scattered moderate to isolated strong convection is noted from 07N to 11N between 94W and 97W. The axis of a tropical wave is near 106W from 03N to 18N, moving westward at 15 kt. Scattered moderate to isolated strong convection is observed from 05N to 13N between 103W and 111W. The axis of a tropical wave is near 128W from 03N to 19N, moving westward at about 10 to 15 kt. Scattered moderate convection is noted from 09N to 13N between 126W and 130W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 10N103W to 08N108W to 12N125W. The ITCZ extends from 11N129W to 08N140W. Aside from the convection associated with the tropical waves, scattered moderate to isolated strong convection is noted from 05N to 12N between 89W and 121W. Scattered moderate isolated strong convection is noted within 60 nm south of the ITCZ. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between low pressure over Mexico and high pressure to the west of Baja California will lead to fresh to locally strong winds near the west coast of Baja California through Thu. High pressure building southward from the Gulf of Mexico will bring strong gap winds from Thu through Sun afternoon across and downwind of the Gulf of Tehuantepec. These winds may reach near gale force late at night on Thu and Fri. Peak seas are anticipated to reach around 8 ft due to the limited area and duration of these gap winds. No significant long-period swell are expected in the Mexican offshore zones for at least the next several days. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong northeast to east winds in the Gulf of Papagayo will continue into early Sat. Mainly moderate monsoonal southwest winds will remain over the waters south of 08N through the period, with some locally fresh winds possible this weekend. No significant long-period swell is expected in the Central American and equatorial offshore zones for at least the next several days. REMAINDER OF THE AREA... High pressure prevails over the northern waters. The pressure gradient between this area of high pressure and lower pressure within the monsoon trough, and in the vicinity of the ITCZ is supporting moderate to fresh winds N of the ITCZ and west of 125W. Seas are in the 5-7 ft range. Moderate to locally fresh southerly winds prevail south of the monsoon trough and ITCZ. Cross equatorial southerly swell is helping for seas in the 7-9 ft range over the waters south of 05N and west of 110W. A weakening cold front or trough is forecast to move over the waters north of 25N from 125W to 130W Thu, ushering in fresh northeast winds and seas in the range of 7-10 ft into early Sat. Global models are suggesting the development of low pressure i association to the tropical wave, currently near 106W, may form in a few days as it moves westward across the central part of the basin. $$ AL
