000 AXPZ20 KNHC 081632 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1605 UTC Mon Jul 08 2019 Corrected Special Features 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 1200 UTC surface analysis and satellite imagery through 1545 UTC. ...SPECIAL FEATURES... The Post-Tropical remnant low of former Tropical Storm Cosme was centered near 20.5N 120.7W at 15 UTC this morning moving to the northwest at 07 kt, with an estimated minimum pressure of 1008 mb. Winds are 20-25 kt within 120 nm of the center in the northern semicircle and within 90 nm of the center in the southeast quadrant along with waveheights of 8-10 ft. The remnant low is devoid of any deep convection as it tracks over cold sea surface temperatures and through a surrounding dry and stable environment. Latest satellite imagery depicts the low as a large swirl of mostly cold-air stratocumulus clouds, with possible isolated patches of rain. The remnant low will continue to move in a general northwest direction through Tue night, with dissipation on Wed. See last issued NHC forecast/advisory issued at 15 UTC under AWIPS/WMO headers MIATCMEP3/WTPZ23 KNHC for more details. ...TROPICAL WAVES... A tropical wave with axis along 87W and north of 04N to central Honduras is moving westward around 15 kt. Very active weather in the form of numerous strong convection is noted from 05N to 12N between 82W and 89W. A tropical wave with axis near 112W from 02N to 14N is moving westward around 15 kt. No significant convection is associated with this wave. The previous tropical wave that was along 132W is presently not identifiable. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from a 1011 mb low over Colombia at 10N76W to 10N85W to 08N110W to 09N110W to 08N119W. The ITCZ extends from 08N119W to 08N136W, then resumes from 09N134W to beyond 09N140W. Scattered moderate to strong convection is noted within 150 nm north of the trough between 89W and 93W. Scattered moderate convection is within 120 nm south of the trough between 89W and 93W, and within 60 nm south of the ITCZ between 134W and 136W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A high pressure ridge persists across the Baja California offshore waters. Overnight scatterometer data showed fresh west winds south of Cabo San Lucas and mainly moderate northwest winds near Punta Eugenia. Little change in the overall pattern is expected through Wed as daytime heating will support locally fresh winds near the coast during the late afternoon and early evening hours. Elsewhere, generally gentle to moderate northwest winds will continue off the coast of Baja California through the next few days. Swell from former Tropical Cyclone Cosme is producing waveheights of 8 ft over the outer waters SW of Cabo San Lazaro with 5-7 ft waveheights near the entrance to the Gulf of California. These seas will subside today as the remnant low of Cosme continues moving away from the region. Gulf of California: The earlier fresh to strong southwest gap over the northern Gulf of California have diminished to moderate to fresh winds this morning, with seas of 4-5 ft range. These gap winds will attain fresh speeds again late tonight. Over the southern portions, gentle to moderate west to northwest winds will become light and variable by Wed, then shift to the southeast Thu through Fri as a low pressure trough strengthens near Baja California. Gulf of Tehuantepec: Fresh to strong northerly gap winds across the Gulf of Tehuantepec will diminish later this morning. Gentle winds will prevail through the rest of the week with seas less than 8 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A north-south pressure gradient across Central America will support pulsing fresh gap winds between the Gulf of Fonseca and the Gulf of Papagayo through Wed. Waveheights downstream of the gulfs will reach 5-7 ft each day. Long period south to southwest swell currently propagating through the waters will diminish by Tue. Another round of southerly swell will begin to propagate through the southern waters beginning late Thu night with waveheights building to 10 ft between Ecuador and the Galapagos Islands on Fri, and 8 ft seas developing over the Central American offshore waters. REMAINDER OF THE AREA... An area of 8 ft waveheights persists over the waters from roughly 10N to 18N west of 135W, likely due to mixed southeast swell and local wind waves generated by moderate to fresh northeast trades. These waveheights will subside through by early on Tue as the swell decays and trade winds weaken slightly. Elsewhere, the pressure gradient across much of the high seas domain remains weak. Recent altimeter data from this morning displayed an area of 8 to near 10 ft waveheights over the waters from 11N to 23N between 114W and 125W. Waveheights will subside below 8 ft by early on Tue as this swell decays. $$ Aguirre
