Juliette will continue to move toward the WNW through tonight. A turn toward the west is forecast to occur on Saturday and a general westward motion should continue into early next week. Additional weakening is expected during the next 48 hours, and Juliette is forecast to degenerate into a remnant low late Saturday or Sunday. Satellite imagery indicates numerous moderate convection within 60 nm W and 30 nm E semicircles. Scattered moderate convection is noted elsewhere from 22N to 24N between 123W and 125W. See latest NHC forecast/advisory under AWIPS/WMO headers MIATCMEP1/WTPZ21 KNHC for more details. ...TROPICAL WAVES... A tropical wave is along 99W from 05N to 15N.

Scattered moderate convection is from 10N to 15N between 110W and 115W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from a 1008 mb low pressure over northern Colombia to 07N80W to 10N99W to 11N120W to 11N113W to 12N125W to 11N140W. Outside of the convection associated with the tropical waves, scattered moderate isolated strong convection is from 05N to 07N east of 81W, from 10N to 13N between 118W and 122W, from 12N to 14N between 126W and 130W, and from 06N to 10N W of 136W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge is building between T.S. Juliette, which is west of the area, and the Baja California peninsula. This will allow for winds to return to the normal NW to N winds across the offshore waters forecast W of Baja by tonight. Then, gentle to moderate NW to N winds will prevail through Sun, with fresh to strong winds N of Punta Eugenia through Sun night. Thereafter, moderate to fresh winds are expected N of Cabo San Lazaro through Tue morning. Elsewhere, moderate to fresh north winds are expected across the Gulf of Tehuantepec mainly at night during the weekend. Fresh to strong southerly winds may develop over the northern Gulf of California early on Sun as a low pressure trough deepens along the Baja California peninsula. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh NE to E winds are expected in the Gulf of Papagayo through Sat. Elsewhere, mainly light to gentle winds will persist N of the monsoon trough, with gentle to moderate south to southwest winds south of the monsoon trough for the next several days. Seas of 5 to 7 ft will dominate much of the forecast waters as long period cross-equatorial SW swell reaches the area during the upcoming weekend. REMAINDER OF THE AREA... Please see the Special Features section above for details on T.S. Juliette. Swell generated by Juliette will continue to propagate outward over the next few days, resulting in a large area of seas greater than 8 ft around the storm. Rough seas will continue near the center of Juliette through the weekend. Elsewhere, gentle to moderate trades will prevail west of 130W and north of the monsoon trough, with little change expected over the next several days. $$ GR
