Scattered moderate to isolated strong convection is noted from 10N to 15N between 100W and 107W. Environmental conditions appear conducive for gradual development of this system during the next few days, and a tropical depression is likely to form early next week while it moves west-northwestward away from the coast of Mexico. This system has a low chance of tropical cyclone formation over the next 48 hours and a high chance of formation through 7 days. Please, refer to the latest Tropical Weather Outlook at www.hurricanes.gov for more details. A second tropical wave is along 133W/134W from 07N to 20N moving W at 10 kt. Scattered moderate convection is observed from 10N to 15N between 130W and 137W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 12N100W to 1011 mb low pressure located near 12N111W to another 1011 mb low pressure situated near 14N124W to 13N140W. Aside from the convection associated with the tropical waves, a cluster of moderate to strong convection is noted from 03N to 07N E of 81W to the coast of Colombia. Scattered moderate to isolated strong convection can be found from 08N to 13N between 90W and 100W, and from 10N to 15N between 110W and 130W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see Tropical Waves section above for details on a tropical wave that has a potential for tropical cyclone development. A ridge dominates the forecast waters off Baja California supporting gentle to locally moderate NW to N winds with moderate seas in mixed SW and NW swell. Mainly gentle SE winds are noted in the Gulf of California with seas of 1 to 3 ft. Fresh N winds are in the Gulf of Tehuantepec where seas are in the 4 to 6 ft range.

Seas are generally 3 to 5 ft in long period SW swell. For the forecast, gentle to moderate S to SW winds will prevail south of the monsoon trough during the next several days while light to gentle winds are expected N of it. Seas will be in the 4 to 6 ft range. ...REMAINDER OF THE AREA... Please see Tropical Waves section above for details on a tropical wave that has a potential for tropical cyclone development. High pressure dominates the waters N of 15N W of 110W generating moderate anticyclonic flow. To the S of the monsoon trough, mainly moderate southerly winds prevail. Seas average 5 to 7 ft. For the forecast, a broad area of low pressure could form by this weekend well to the west-southwest of the southern tip of the Baja California peninsula.
