000 AXPZ20 KNHC 271455 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1240 UTC Sat Jul 27 2019 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 1450 UTC. ...SPECIAL FEATURES... Recently developed Tropical Depression Six-E centered near 11.3N 123.8W at 27/1500 UTC moving W at 16 kt. Estimated minimum central pressure is 1006 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Numerous moderate scattered strong convection was noted within 60 nm E semicircle and N quadrant. Scattered moderate isolated strong convection was elsewhere from 09N to 15N between 120W and 126W. The depression is forecast to reach tropical storm strength later today, and continue to intensify the next several days as it moves on a general west to west northwest track. Please see latest NHC forecast/advisory under AWIPS/WMO headers MIATCMEP1/WTPZ21 KNHC for more details. ...TROPICAL WAVES... The axis of a tropical wave is near 83W N of 03N, moving W at 15 kt. Scattered moderate isolated strong convection is noted from 05N to 10N between 83W and 87W. The axis of a tropical wave is near 100W from 03N to 15N, moving W at 15 kt. Scattered moderate to strong convection is noted from 06N to 13N between 97W and 104W. This wave has potential for possible tropical cyclone development over the next several days. There is a high probability for tropical cyclone formation, and a tropical depression is likely to form early next week. Please see the latest eastern North Pacific Tropical Weather Outlook for more information. The axis of a tropical wave is near 110W from 04N to 17N, moving W at 10 to 15 kt. Scattered moderate isolated strong convection is noted from 08N to 13N between 107W and 114W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 07N82W to 09N98W to 13N111W. The ITCZ extends from 10N125W to 08N134W to 09N140W. Scattered moderate isolated strong convection was noted N of 04N E of 80W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak ridge will dominate the waters west of Baja California through Wed, with gentle to moderate winds prevailing. Fresh to strong gap winds will prevail across the Gulf of Tehuantepec this weekend before diminishing Mon. Winds will then pulse to fresh to strong during the overnight hours. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong gap winds will prevail across and extend well downstream of the Gulf of Papagayo through Tue, with seas remaining in the 7 to 9 ft range. Gentle to moderate NE to E winds will prevail elsewhere N of the monsoon trough. Gentle to moderate S to SW winds will prevail south of the monsoon trough. REMAINDER OF THE AREA... Please see above for more on newly developed Tropical Depression Six-E. Elsewhere, a ridge prevails across the forecast waters N of 25N. Outside of TD Six-E, the pressure gradient across the area is fairly weak. This is resulting in mainly gentle to moderate winds north of the ITCZ/monsoon trough. There is the potential for another tropical cyclone to develop over the forecast waters early next week. Please see the tropical wave section above for more information. The combination of a strengthening ridge, Six-E, and possible another tropical cyclone developing early next week will help for an increase in winds across the waters N of 10N. Outside of the tropical systems, moderate to fresh winds will prevail. Moderate to fresh winds prevail S of the ITCZ/monsoon trough. This is helping to maintain seas in the 6-8 ft range across this area, as cross equatorial SE and S swell are moving through the area. These seas will slowly subside over the weekend. $$ AL
