offshores where seas are in the 5 to 7 ft range in northerly=20
swell. Light to gentle winds prevail over the remainder of the=20
forecast waters with 4-5 ft seas.=20

For the forecast, the pressure gradient between a ridge of high
pressure across the waters west of Baja California and a surface
trough over Mexico will support fresh to strong NW winds over=20
the Gulf of California through Sat evening. Strong winds will=20
also continue to funnel through the Baja California peninsula=20
mountain passages into the offshore waters during this period.=20
The next gale-force gap wind event in the Gulf of Tehuantepec
will begin this morning, with winds increasing to storm-force=20
late tonight into Sat, back to gale-force on Sat and diminishing
below gale-force Sun afternoon. Gentle to moderate winds will=20
prevail elsewhere.

Moderate to fresh gap winds prevail across the Papagayo region as
well as over the Gulf of Panama. Light to gentle winds prevail=20
elsewhere. Seas of 3-5 ft in S to SW swell are noted over the=20
discussion waters.

For the forecast, moderate to fresh NE winds in the Papagayo=20

strong speeds Sat and Sat night. Moderate to fresh N winds over=20
the Gulf of Panama will continue through the middle of next week.
Elsewhere, light to gentle winds will prevail across the Central
American and equatorial waters. Swell generated from a storm-force
gap wind event in the Gulf of Tehuantepec will produce large=20
seas over the Guatemala and El Salvador offshore waters this=20
weekend into early next week.

High pressure of 1032 mb is centered north of the area. The=20
pressure gradient between this area of high pressure and lower=20
pressure in the vicinity of the ITCZ is supporting fresh to=20
strong winds north of the ITCZ to near 25N and west of about=20
122W. Moderate to fresh winds are elsewhere north of the ITCZ=20
and west of 115W. Seas over the area of strongest winds are in=20
the 8-10 ft range as indicated by a recent altimeter data. Gentle
to moderate winds and seas of 5-7 ft are elsewhere.

For the forecast, the area of high pressure will remain north of
the area the next several days. This will maintain an area of=20
fresh to strong NE trades over the waters from 10N to 20N and=20
west of 120W. The winds will start to diminish slowly beginning
Fri and through the weekend. Seas of 8-10 ft will remain between
10N and 25N west of 120W through Fri.
