Based on 1800 UTC surface analysis and satellite imagery through 2040 UTC. ...SPECIAL FEATURES... Low pressure of 1007 MB is centered near 13N115W. This afternoons scatterometer pass indicated fresh to strong winds over the SW quadrant of the low. Scattered moderate isolated strong convection was noted from 05N to 17N between 110W and 118W. The low continues to show signs of organization and environmental conditions are favorable for additional gradual development of the low. There is currently a high chance that a tropical depression will form in the next day or two as the system moves slowly northwestward. By late this weekend, conditions will become less conducive for development. Please refer to Special Tropical Weather Outlook TWOEP/ABPZ20 KNHC for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 09N78W to 05N89W. The ITCZ extends from 08N122W to beyond 05N140W. Scattered moderate isolated strong convection was noted from 02N to 08N E of 97W. Scattered moderate isolated strong convection was noted from 02N to 11N between 105W and 110W. Scattered moderate convection was noted within 60 nm N of the ITCZ W of 130W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A surface trough extends across the Baja California peninsula. The pressure gradient has loosened across the area. Most recent ASCAT pass indicates gentle to moderate winds prevail west of Baja California Sur, with light to gentle winds prevailing over the remainder of the forecast waters. Seas are in the 6-8 ft range off Baja California Norte in NW swell. Over the remainder of open waters, seas in the 4-6 ft range prevail. Seas are 2 ft or less over the Gulf of California. Weak surface troughing will prevail over the Baja California region through early next week. High pressure will then start to build into the region from the west. Seas west of Baja California Norte will remain in the 6-8 ft range. A pulse of fresh to strong northerly winds is likely in the Tehuantepec region Sun night. Otherwise, fairly tranquil marine conditions will prevail elsewhere through the middle of next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A weak pressure pattern is resulting in mostly light to gentle winds across the forecast waters. Seas are mainly 4 to 5 ft in a mix of long period southerly and NW swell. Fairly tranquil marine conditions are expected across most of the forecast area through Wed, except for the Papagayo region, where fresh to occasionally strong gap winds are possible. REMAINDER OF THE AREA... Please see special features above for more on the potential for tropical cyclone development. High pressure prevails north of the area. Outside of the strong winds associated to the low pressure center in the special features section, most recent ASCAT data indicate gentle to moderate winds N of 07N and W of 120W. Seas over this area are in the 6-9 ft range. Gentle to moderate winds will prevail over this area through the beginning of next week. High pressure will start to build the beginning of next week which will help to freshen tradewinds by midweek. Long- period NW swell should cause combined seas to remain 6 to 7 ft west of 120W this weekend. S swell will likely produce combined seas to 7 ft in equatorial waters west of 100W through Sat. $$ AL
