Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
231 PM PDT Wed Jul 31 2024

.SYNOPSIS...Moderate to fresh winds will continue to pulse in 
the Gulf of Papagayo through Thu. Elsewhere, gentle to moderate 
winds and moderate seas will persist through the end of the 
forecast period with little change in seas. Looking ahead, an 
area of low pressure is expected to form south of Central America
and Southern Mexico later this week, where environmental 
conditions appear conducive for gradual development. A tropical 
depression is likely to form by this weekend as the system moves 
westward to west-northwestward at 10 to 15 kt during the next 
several days, remaining offshore.
