000 FZPN28 KNHC 080355 OFFPZ8 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 855 PM PDT Sun Jun 7 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. PMZ101-081600- Synopsis for the E Pacific within 250 nm of Central America, Colombia, and within 750 nm of Ecuador 855 PM PDT Sun Jun 7 2026 .SYNOPSIS...New large SW swell will surge across the Central America offshore waters today through early Tue. As a result, moderate seas will quickly become rough by this evening, and then very rough by Mon morning, building to around 11 ft between Ecuador and the Galapagos. At the same time, convergent monsoonal winds will generate periods of heavy showers and strong thunderstorms across the regional offshore waters at least into early next week. Low pressure south of El Salvador will gradually strengthen the monsoonal SW to W winds across the offshore waters of Central America tonight through Mon night, leading to fresh to strong SW to W winds tonight, becoming strong to near- gale while expanding northward on Mon. Environmental conditions are conducive for further development of this system, and a tropical depression is likely to form during the next day or two while the system moves slowly northward toward the coast of Central America. Interests along the Pacific coasts of northwestern Costa Rica, Nicaragua, Honduras, and El Salvador should monitor the progress of this system. $$ PMZ111-081600- Guatemala and El Salvador to 250 nm offshore- 855 PM PDT Sun Jun 7 2026 .TONIGHT...SW to W winds 20 to 25 kt.
