000 AXPZ20 KNHC 112153 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Mon Apr 11 2022 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07N78W to 07N110W. The ITCZ extends from 05N123W to 03N to 140W. Scattered moderate isolated convection is noted from 03N to 08N between 77W and 100W. Scattered moderate convection is also noted from 07N to 13N between 100W and 111W. Isolated moderate convection is noted from 04N to 12N between 111W and 130W. Isolated weak convection is noted from 03N to 06N between 130W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO The gradient between high pressure over the eastern Pacific and lower pressure over the western U.S. is causing fresh to strong NW winds off Baja California Norte. Scatterometer data confirmed fresh SW winds are funneling across Baja, into the northern Gulf of California. Tue morning, a cold front enters the region from the North, reinforcing the strong NW winds through early Wed. Northerly swell of 10-12 ft prevails north of 29N, increasing to 12-14 ft after frontal passage Tuesday. Swell above 8 ft currently extends south to 24N and will reach as far south as 21N by Wednesday before seas begin to abate across the area. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR High pressure north of the area will support pulses of fresh to strong winds into the Papagayo region into mid week. Fresh winds will pulse in the Gulf of Panama tonight, gradually diminishing to gentle through midweek. Gentle to moderate S winds will prevail between Ecuador and the Galapagos Islands through the next few days. Mainly light to gentle winds are expected elsewhere. S to SW swell will build to 8 ft through early Tue south of the Galapagos Islands before abating. REMAINDER OF THE AREA The gradient between a 1033 mb high pressure centered north of the area near 36N143W and lower pressure over California, Mexico and the deep tropics is producing moderate to fresh anticyclonic flow north of 05N and west of 115W. Seas within this area are 6-8 ft south of 15N and 8-12 ft north of 15N. Long period swell from the southern hemisphere is affecting the area south of 05N between 100W and 120W, with seas in the 7-9 ft range. For the forecast, northerly swell will spread southward, with seas greater than 8 ft covering much of the waters north of 10N and west of 115W by tonight. A cold front will enter the waters north of 25N by early Tue morning, extending from 31N114W to 28N122W to 30N131W. The front will continue southward before dissipating Tue night. The front will bring a reinforcing northerly swell to the area east of 125W and north of 22N Tue through Wed. After the cold front dissipates, conditions improve and the majority of 8 ft seas will abate by Thu. Southerly swell affecting areas south of 05N will gradually abate through the week. $$ FLYNN
