000 AXPZ20 KNHC 150331 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0245 UTC Wed Jul 15 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... A tropical wave has its axis along 88W and north of 03N to across El Salvador and into the Gulf of Honduras. It is moving westward at 10 to 15 kt. Scattered moderate to isolated strong convection is noted from 05N to 10N between 83W and 89W. A tropical wave has its axis along 102W from 03N to near Acapulco, Mexico. It is moving westward at 115 kt. Scattered moderate to isolated strong convection is noted from 06N to 12N between 98W and 101W. A tropical wave axis is along 123W from 03N to 18N, moving westward at 10 to 15 kt. This wave is associated with the remnantsof Tropical Depression Six-E. Scattered moderate to isolated strong convection is noted from 07N to 15N between 117W and 127W. A tropical wave has its axis along 129W from 02N to 13N. It is moving westward at 10-15 kt. Scattered moderate to isolated strong convection is occurring from 06N to 10N between 127W and 130W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N86W to 09N100W to 11N115W to 12N140W. Aside from the convection described above in association with the tropical waves, scattered moderate to isolated strong convection is seen from 05N to 10N between 89W and 97W. Scattered moderate convection is noted from 02N to 12N between 130W and 136W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient related to a trough over Baja California is allowing for areas to the west to have fresh to locally strong northwest winds, which will continue until Fri. High pressure building into the Gulf of Mexico late Thu through Fri night will lead to strong gap winds in and downwind of the Gulf of Tehuantepec from Thu night into early Sun. While current guidance suggest near-gale conditions late 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 are ongoing in the Papagayo region and well continue through Wed. Peak seas with these winds may reach 8 ft. Moderate to locally fresh fresh monsoonal southwest winds will remain over the waters S of 09N through into late week. No significant long-period swell are expected in the Central American and equatorial offshore zones for at least the next several days. REMAINDER OF THE AREA... A weakening 1011 mb low pressure is centered near 18N119W, moving west around 15 kt. Fresh NE winds and seas of 5 to 7 ft are located within 60 nm of the northern semicircle. Weakening is expected to continue and the low may degenerate into a trough by Wed morning. Another weakening 1011 mb low pressure is centered near 23N136W, moving west at 10 kt. The gradient between the low and 1032 mb high pressure well NNW of the area is inducing an area of strong E winds to the north of the low. The low will shift W of the area Wed, leading to diminish winds E of 140W. Seas of 8 to 10 ft in the area will also slowly subside into Wed night. Moderate to fresh south winds remain to the south of the monsoon trough between 110W and 125W. These winds are combining with some southwest swell resulting in combined seas of 8 to 10 ft. These will progress westward before diminishing Thu night. A weak cold front is likely to move into waters N of 25N from 125W to 140W Thu, bringing fresh NE winds and seas of 8 to 10 ft through Fri night. $$ KONARIK
