Light to gentle winds are noted elsewhere over the open waters
off Mexico. Seas are in the 4-6 ft range. Over the Gulf of
California, gentle to moderate winds and seas of 2-4 ft prevail.
For the forecast, an area of low pressure could form several
hundred miles offshore of southwestern Mexico late this week.
Environmental conditions are expected to only be marginally
conducive for development of this system as it moves to the west-
northwest, well off the coast of Mexico. Winds may strengthen in
the northern Gulf of California late in the week. Otherwise,
gentle to moderate winds will prevail across the forecast waters,
except pulsing to moderate to fresh in the Gulf of Tehuantepec

For the forecast, fresh to strong E winds will pulse in the Gulf
of Papagayo through Wed night, diminishing to moderate to fresh
thereafter. Otherwise, gentle to moderate winds will prevail.
Moderate seas in S to SW swell will prevail over the regional
waters during the period, building near rough south of the
Galapagos Islands by the end of the week.
...REMAINDER OF THE AREA...
Broad pressure prevails over the waters north of 20N. Gentle to
moderate winds prevail across the discussion waters, except
moderate to fresh in the west central waters where seas are in

over the next few days. Cross equatorial, rough southerly swell
will move into the waters S of 06N and W of 100W by the middle
of the week, persisting into the weekend. Seas may build to near
8 ft in fresh N swell along 30N between 120W and 130W at the end
of the week into the weekend. Winds may freshen in the NW waters
by the weekend.
