OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of Tehuantepec: Fresh northerly winds will diminish today, with light and variable winds prevailing afterwards through Thu. Gulf of California: Light to gentle winds prevail across the forecast waters. Winds will freshen early Tue before diminishing Fri. The pressure gradient between a nearly stationary high pressure ridge to the west of Baja and troughing along the Gulf of California will support N to NW moderate to fresh winds off the coast of Baja California through Fri. Southerly swell generated from Tropical Storm Barbara will bring seas to 8 ft over the offshore waters of Baja California through the week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong winds will prevail across the Gulf of Papagayo through the week. Elsewhere, moderate offshore winds will prevail N of the monsoon trough, with moderate S to SW winds expected S of the monsoon trough the next few days. S to SW swell will build wave heights to near 9 ft over the waters S of the equator by late Mon before subsiding. REMAINDER OF THE AREA... Please see above for more of Tropical Storm Barbara. Outside of T.S. Barbara, a broad ridge dominates the northern forecast waters. Moderate trades prevail N of the ITCZ and south of the ridge W of 125W, with seas in the 5 to 8 ft range in mixed swell. T.S. Barbara will continue to propagate westward across the waters west of 115W. Swell generated from T.S. Barbara will spread across the forecast waters, with seas 8 ft or greater covering much of the forecast waters west of 120W by late Thu. Cross equatorial SE and SW swell 8 to 10 feet will prevail much of the week across waters S of 04N. Low pressure may form 210 to 360 nm S and SW of the southern coast of Mexico in the latter portions of the week. This could lead to increased winds and seas. $$ KONARIK
