Moderate or lighter winds are forecast elsewhere through the forecast period. ...REMAINDER OF THE AREA... A subtropical ridge dominates the waters N of 15W and W of Baja California supporting moderate to fresh trade winds north of the monsoon trough and ITCZ to 20N. Seas in these waters are 5-6 ft. In the eastern waters, moderate to fresh NE to E winds and seas of 6-7 ft are noted north of 10N and east of 102W due to gap wind event ongoing in Tehuantepec.
