Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
636 PM PST Sun Dec 22 2024

.SYNOPSIS...The pressure gradient between high pressure
extending southward over the western Caribbean and the eastern
north Pacific monsoon trough will support fresh gap winds
pulsing to strong winds in the Papagayo region into Tue, then 
moderate to fresh thereafter. Gales in the Tehuantepec region 
will generate northerly swell and rough seas well offshore 
Guatemala through tonight. Elsewhere, winds will be moderate or 
weaker with moderate seas through mid-week, pulsing to moderate 
to fresh in the Gulf of Panama at times. A surge of at least
fresh NW to N winds may move across the offshore waters of 
Guatemala mid- week. Seas will build Wed as the strong NW swell 
moves into the regional waters.
