For the forecast, winds may strengthen in the northern Gulf of California late in the week. Otherwise, gentle to moderate winds will prevail across the forecast waters, pulsing to moderate to fresh in the Gulf of Tehuantepec through mid-week. Moderate seas will prevail across the open waters over the next several days. 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. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR...
