FZPN28 KNHC 091539 OFFPZ8 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 839 AM PDT Thu Jul 9 2026 Offshore Waters Forecast for the E Pacific within 250 nm of Central America, Colombia, and within 750 nm of Ecuador Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. PMZ101-100345- Synopsis for the E Pacific within 250 nm of Central America, Colombia, and within 750 nm of Ecuador 839 AM PDT Thu Jul 9 2026 .SYNOPSIS...Fresh to strong NE-E gap winds will pulse in the Gulf of Papagayo region through late Sun, mainly at night and into the morning hours. Gentle to moderate breezes and slight to moderate seas will persist elsewhere. An area of low pressure is expected to form late this weekend or early next week several hundred miles south-southwest of the coast of southwestern Mexico. Environmental conditions appear favorable for gradual development thereafter, and there is a medium chance a tropical depression could form next week while the system moves generally west- northwestward. Regardless of tropical cyclone formation, the lowering pressure may induce at least fresh to strong winds and rough to very rough seas offshore El Salvador and Guatemala by Sun. $$ PMZ111-100345- Guatemala and El Salvador to 250 nm offshore- 839 AM PDT Thu Jul 9 2026 .TODAY...NE winds 10 kt.
