PMZ101-020945- Synopsis for the E Pacific within 250 nm of Central America, Colombia, and within 750 nm of Ecuador 239 PM PDT Sun Jun 1 2025 .SYNOPSIS...Long-period southern hemispheric swell will propagate northeastward through the equatorial waters, promoting rough seas offshore of Ecuador and well offshore of Guatemala and El Salvador into Mon. Seas will subside late Mon. Looking ahead, an area of low pressure is forecast to form offshore of the coast of Central America and southern Mexico during the middle to late portions of this week. Once it forms, the disturbance is expected to move generally westward to west-northwestward around 10 mph. Environmental conditions are expected to be at least marginally conducive for gradual development of this system, and a tropical depression could form by the end of the week. $$ PMZ111-020945- Guatemala and El Salvador to 250 nm offshore- 239 PM PDT Sun Jun 1 2025 .TONIGHT...SE winds 10 kt in the evening, becoming variable winds less than 5 kt.
