...INTERTROPICAL CONVERGENCE ZONE...
The ITCZ axis extends from 03N102W to 02N132W with no sizable
areas of significant convection.
OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A cold front from SW Arizona across extreme northern part of the
Gulf of California and northern Baja California will shift east
across Baja California Norte and the northern Gulf of California
today. High pressure behind the front will maintain fresh NW
winds west of Baja California this morning. Strong high pressure
building near 33N132W early next week will increase the coverage
of strong northwest winds north of 25N off the coast of Baja
California Norte early next week. Seas in the 6-8 ft range will
prevail over this area through Monday. Northwesterly swell will
propagate into the waters off Baja California Norte Monday, and
peak near 12 ft early Tuesday morning.
Gentle to moderate northerly winds and seas of 2-3 ft are
expected across northern Gulf of California with the frontal
passage. Winds are forecast to increase to 15-20 kt with seas
building to 6 ft Tuesday and Wednesday as the above mentioned
area of high pressure builds and tightens the pressure gradient
over the area. Elsewhere, winds will generally be light to gentle
with seas in the 4-6 ft range through the middle of next week.
OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND
WITHIN 750 NM OF ECUADOR...
Fresh NE winds are expected over the Gulf of Papagayo during the
late night and early morning hours through Monday morning. Light
to gentle winds and seas of 3-5 ft are expected elsewhere the
next several days except in the Gulf of Panama, where winds will
pulse to a fresh breeze at night.
REMAINDER OF THE AREA...
A cold front extends across NE waters from 30N116W to 25N130W.
High pressure behind the cold front extends a ridge SE to near
the Revillagigedo Islands. On the southern periphery of the
ridge, fresh to strong trades prevail from 07N to 19N W of 130W.
Seas have built to 10-11 ft within the area of strongest trade
winds based on altimeter data. This area of trades will persist
through Monday, and the aerial extent of the fresh trades will
increase by Monday night as high pressure located north of the
area near 34N133W strengthens.
