PMZ101-222045- Synopsis for the E Pacific within 250 nm of Central America, Colombia, and within 750 nm of Ecuador 145 AM PDT Sun Jun 22 2025 .SYNOPSIS...Fresh NE winds will pulse to strong at night across the Papagayo region through Tue as strong trade winds continue over the southwestern Caribbean. Elsewhere, moderate to fresh S to SW winds are expected south of the monsoon trough through early next week. Low pressure is expected to develop just SW of the Papagayo region by Mon, and will enhance the gap wind flow there and lead to locally rough seas well offshore of Costa Rica and Nicaragua late Mon through Tue night. Looking ahead, this area of low pressure is expected to move west-northwestward just off the coasts of Central America and southern Mexico throughout the coming week. Environmental conditions appear conducive for gradual development and a tropical depression is likely to form by the middle of next week. There is a high chance of formation within the next 7 days. $$ PMZ111-222045- Guatemala and El Salvador to 250 nm offshore- 145 AM PDT Sun Jun 22 2025 .TODAY...N to NE winds 10 kt.
