235 PM PDT Mon May 13 2024

.SYNOPSIS...Gentle to moderate southerly winds are forecast 
south of the monsoon trough through the end of the week. 
Southerly swell moving through the regional waters will support 
seas of 5-7 ft south of the Galapagos Islands through the 
forecast period. An area of low pressure is forecast to form 
south of the Gulf of Tehuantepec by mid to late week and move 
west-northwestward. This will increase the winds and seas in the 
offshore waters of Guatemala and El Salvador toward the end of 
the week and into the upcoming weekend.
