000 AXPZ20 KNHC 032138 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1605 UTC Tue May 3 2022 Corrected Offshore Waters Within 250 nm of Mexico section Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1545 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from northwestern Colombia to 09N84W to 10N97W to 07N108W and to 07N115W, where latest scatterometer data indicates that it transitions to the ITCZ and continues to 07N122W to 07N132W and to beyond 07N140W. Numerous moderate to strong convection is noted from 06N to 09N between 98W-102W. Scattered moderate convection is within6 nm north of the ITCZ west of 139W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO...Corrected A 1029 mb surface high is centered west-northwest of the area near 32N147W extends a broad ridge southeastward to near 23N118W. This This alignment is producing a weak pressure pattern across the regional waters. Overnight ASCAT data showed moderate to fresh NW to NNW winds prevailing to the west of Baja California north of 22N. NNW swell is producing seas of 6-8 ft across the Baja California waters north of Cabo San Lazaro, and 4-6 ft elsewhere across the Mexican waters to Puerto Angel. Overnight ASCAT data also showed moderate S winds over the northern Gulf of California, where seas remain 2-3 ft. Gentle to moderate winds are in the southern Gulf. ASCAT data also showed mainly gentle winds elsewhere along the coast of Mexico, from Manzanillo to Puerto Angel. The surface high pressure west-northwest of the area will move eastward, allowing northwesterly winds west of Baja California to remain moderate to fresh through tonight. Moderate to fresh southerly winds will pulse in the northern Gulf of California today, then diminish to gentle tonight. W to NW winds just west and south of Baja California Sur will continue pulsing to fresh at night through Wed night. NNW swell will continue west of Baja California through Thu before new NW swell moves into the area. Looking ahead, a cold front is forecast to reach Baja California Norte this weekend, bringing fresh to strong winds west of Baja California Norte, and seas building in excess of 10 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Overnight ASCAT data showed variable gentle winds across the offshore waters north of the monsoon trough, and gentle westerly winds to the south of the trough. Seas are 4-5 ft in S to SW swell across these waters. Isolated showers and thunderstorms are over most of these waters. Gentle to moderate S to SW winds offshore Colombia and Ecuador will increase to moderate to locally fresh beginning late this afternoon and through Thu morning. Easterly winds off the Papagayo region and southern Nicaragua will pulse to moderate during the overnight and early morning hours through Thu morning. Long-period S to SW swell will reach the waters off South America Wed, and the waters off Central America by Wed night, then persist through Fri. REMAINDER OF THE AREA The pressure gradient between the 1029 mb high pressure located west-northwest of the area near 32N147W and lower pressure in the vicinity of the ITCZ is maintaining moderate to fresh NE trades north of the ITCZ to about 28N and west of 130W. Moderate tradewind swell over this area is maintaining seas at 8 to 10 ft. A weakening cold front extends from extreme southern California to 29N126W and to near 31N140W. It will dissipate by this afternoon as it continues to push southward over the north- central and northeast waters. Moderate N to NE winds and 6 to 7 ft seas are south of the front between 120W-128W. A rather consolidated area of numerous moderate to strong convection is evident near the monsoon trough roughly between 104W-109W, where a surface trough is analyzed along 107W this morning. Elsewhere seas to 8 ft in SW swell are present south of 01S between 99W- 133W. The aforementioned fresh NE trades are expected to persist S of 27N and W of 130W through Thu as reinforcing high pressure behind the sinking cold front prevails. New long-period NW swell will enter the area from the northwest late Wed, then spread southeastward across much of the area through Fri. Long-period SW swell will increase slightly south of 05N and east of 125W late tonight into Wed night before gradually subsiding Thu. The surface trough along 107W is forecast to linger through Thu, and perhaps become re-aligned in a northeast to southwest position. Looking ahead, new NNW swell will enter the NE part of the area late Sat through Sun. $$ Aguirre
