A ridge of high pressure extends over the waters north of 20N. Outside of conditions associated with Hurricane Douglas, the pressure gradient between the ridge and the monsoon trough is supporting moderate NE trade winds north of the monsoon trough west of 120W with seas in the 5 to 7 ft range. Winds in this region are forecast to increase to moderate to fresh over the weekend as the ridge strengthens. Meanwhile, cross-equatorial southerly swell will continue to move into region, occasionally supporting combined seas nearing 8 ft east of 120W. $$ Christensen
