OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge west of the area will support gentle to moderate 
northwest breeze west of the Baja Peninsula through late today. 
Moderate to locally fresh conditions will develop west of Baja on
this evening, and then continue through Sat night.

The monsoon trough will gradually shift southward as low 
pressure north of the area weakens. This pattern will support

to moderate easterly winds north of the monsoon trough. Seas in 
the 3 to 5 ft range will prevail over the area.

fresh trades, and 7 to 8 ft seas, are observed across the 
tropics south of the ridge from 09N to 15N west of 135W. Seas 
will subside below 8 ft today.

Northerly swell, with seas of 8 to 10 ft, prevail NW of a line 
from 30N120W to 22N140W. These seas will gradually subside to
