continues from 08N90W to 07N100W to 10N130W. It then resumes 
from 10N135W to beyond 09N140W. Scattered moderate isolated 
strong convection is noted from 08N to 10N between 115W and 121W,
from 10N to 18N between 121W and 133W, and from 08N to 10N 
between 133W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Strong to near- gale winds, and seas to 9 ft, prevail over the 
Tehuantepec region. Moderate winds prevail over the southern 
Gulf of California as well as west of Baja California Sur. Light 
to gentle winds prevail elsewhere. Seas are in the 4-6 ft range,
except 1-3 ft over the northern Gulf of California. 

For the forecast, strong to near gale winds over the Gulf of
Tehuantepec will gradually diminish through Sun. Moderate to 
locally fresh NW winds at the entrance of the Gulf of California,

High pressure prevails over the waters north of 20N, anchored by
1021 mb high pressure centered near 29N121W. A surface trough 
extends from 15N132W to 10N132W. The pressure gradient between 
the area of high pressure and the surface trough is supporting 
fresh to locally strong winds just NE of the trough. Moderate to 
locally fresh winds prevail elsewhere north of the ITCZ to near 
20N and west of 115W. Light to gentle winds prevail north of 20N.
