FZPN27 KNHC 181614 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 914 AM PDT Sat Jul 18 2026 Offshore Waters Forecast for the E Pacific within 250 nm of Mexico 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. PMZ001-190415- Synopsis for the E Pacific within 250 nm of Mexico 914 AM PDT Sat Jul 18 2026 .SYNOPSIS...Tropical Storm Elida is centered near 18.9N 123.3W at 8 AM PDT, and is moving north-northwest at 10 kt. Maximum sustained winds are 60 kt with gusts to 75 kt, and the minimum central pressure is 990 mb. Elida will move to near 20.1N 124.1W this evening, 21.9N 125.2W Sun morning, 24.0N 126.1W Sun evening, 26.4N 126.7W Mon morning, become post-tropical and move to 28.9N 127.2W Mon evening, and weaken to a remnant low near 31.4N 127.5W Tue morning. Outer associated conditions will improve across the area Sat. As Elida moves toward the NW, the ridge over Baja California will weaken leading to mainly light to gentle winds. However, seas generating by Elida will propagate across the offshore forecast waters of Baja California today through Sun. Expect building seas of 8 to 10 ft, mainly across the outer forecast waters. In the Gulf of California, gentle to moderate winds and slight seas will prevail, except for locally fresh winds in the northern Gulf at times. Fresh to strong northerly winds will continue to pulse in the Gulf of Tehuantepec through the next several days, with locally rough seas at times. Meanwhile, a tropical wave near 107W has the potential for tropical cyclone formation. Regardless of tropical cyclone formation, expect increasing winds and building seas to impact portions of the waters well offshore southwest Mexico to the Revillagigedo Islands this weekend into early next week. $$ PMZ009-190415- Mexico Border S to 30N within 60 nm of shore- 914 AM PDT Sat Jul 18 2026 .TODAY...Variable winds less than 5 kt.
