000 AXPZ20 KNHC 302301 AAA TWDEP Tropical Weather Discussion...Updated NWS National Hurricane Center Miami FL 2301 UTC Sat Jul 30 2022 Updated Remainder of Area 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 1800 UTC surface analysis and satellite imagery through 2245 UTC. ...SPECIAL FEATURES... Hurricane Frank is centered near near 17.2N 117.1W at 30/2100 UTC moving NW at 10 kt. Estimated minimum central pressure is 975 mb. Maximum sustained wind speed is 80 kt with gusts to 100 kt. Peak seas are currently 31 ft. Bands of very deep convection of the numerous moderate to strong type intensity are noted on satellite imagery near the center, and within 120 nm of the center in the SW and NW quadrants. Scattered moderate isolated strong convection is within 90 nm of the center in the SE quadrant, and within an outer wide band that is within 30 nm either side of a line from 13N120W to 14N115W to 16N114W, and from 16N114W to 18N115W and to 19N117W. Scattered moderate convection is within 90 nm of the center in the NW quadrant. Frank is moving toward the northwest and this general motion is forecast to continue for the next few days. After that, Frank should should start weakening on Sun as it moves over colder water. Tropical Storm Georgette is centered near 13.6N 127.7W at 30/2100 UTC moving WSW at 8 kt. Estimated minimum central pressure is 999 mb. Maximum sustained wind speed is 45 kt with gusts to 55 kt. Peak seas are currently near 15 ft. Deep convection has maintained rather persistent convection throughout the day. Satellite imagery shows that this convection is of the numerous moderate to strong type intensity within 90 nm of the center in the SW quadrant, and within 60 nm of the center in the NW quadrant. Georgette is forecast begin to slow in the next day or so, resulting in a meandering motion through the remainder of the weekend. A turn toward the northeast is expected by early next week. Little change in strength is forecast during the next day or so, with gradual weakening anticipated after that. Please read the latest High Seas Forecast issued by the National Hurricane Center at https://www.nhc.noaa.gov/MIAHSFEP2.shtml and the latest NHC Forecast/Advisory and Public Advisory at www.hurricanes.gov for more details on Frank and Georgette. ...TROPICAL WAVES... A tropical wave has its axis along 103W from 04N to 18N, moving westward around 10 kt. Scattered moderate to isolated strong convection continues to increase west of the wave to 108W from 07N to 15N. Scattered moderate within 180 nm east of the wave from 07N to 12N. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 10N85W to 09N95W to 12N103W and continues NW to 15N108W. It resumes well to the SW of Hurricane Frank at 09N133W to 08N140W. Scattered moderate convection is within 120 nm S of the trough between 90W-94W and between 97W-100W. Similar activity is within 60 nm S OF the trough between 134W-137W, and within 30 nm of the trough between 137W-140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for details on Hurricane Frank. Weak high pressure remains over the offshore waters of Baja California N of Cabo San Lazaro. Latest ASCAT data passes show light to gentle NW-N winds over these waters. The ASCAT data passes also reveal light to gentle winds over the remainder of the Mexican offshore waters, with the exception of gentle to moderate SW winds from near Los Cabos to the entrance to the Gulf of California, and fresh to strong northerly winds in the Gulf of Tehunatepec. Seas are in the 4-6 ft range W of Baja California, 6-7 ft in the Gulf of Tehuantepec, and 8-11 ft near the Revillagigedo Islands due to the close proximity of Hurricane Frank. For the forecast Hurricane Frank, west of the offshore waters near 17.2N 117.1W 975 mb at 2 pm PDT is moving NW at 10 kt. Frank will continue on the this general motion for the next few days, reaching near 18.1N 118.2W late tonight, then begin to gradually weaken as it nears 19.5N 119.8W early Sun afternoon, to near 20.8N 121.3W late Sun night with maximum sustained winds 65 kt gusts 80 kt, and weaken to a tropical storm near 22.1N 122.7W early Mon afternoon with maximum sustained winds 55 kt gusts 65 kt. Frank is forecast to reach near 23.5N 124.1W late Mon night with maximum sustained winds 45 kt gusts 55 kt, to near 24.9N 125.4W early Tue afternoon with maximum sustained winds 35 kt gusts 45 kt and weaken to a remnant low near 27.5N 127.0W early Wed afternoon. For the forecast outside of Frank, mainly light to gentle to moderate NW-N winds will continue across the waters N of Cabo San Lazaro. Winds have shifted to E-SE winds over the waters between Cabo Corrientes and Cabo San Lazaro due to the outer influence of Frank. These winds were captured in a recent ASCAT data pass. Seas generated by Frank will continue to propagate across this area, building seas in excess of 8 ft, possibly reaching peak heights of around 14 or 15 ft in the most outer boundaries of the offshore waters zone that are between Cabo San Lazaro and Cabo San Lucas. In the Gulf of California, mainly gentle to moderate SE to S winds will change little through early Sun evening, then diminish slightly going into the early part of next week. Fresh to strong northerly winds are forecast to persist in the Gulf of Tehuantepec, and downwind to about 14N into next week. Seas there are forecast to reach 8 ft by early Sun and change little into next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Latest ASCAT data depicts moderate to fresh northeast to east over and downwind of the Gulf of Papagayo. Gentle to moderate winds are elsewhere north of the monsoon trough while gentle to moderate S to SW winds are south of the monsoon trough. Seas are generally 3-5 ft in a S to SW swell, except 5-7 ft between Ecuador and the Galapagos Islands. For the forecast, gentle to moderate winds will remain across the region through at least Mon, with slight to moderate seas in south to southwest swell. Winds will pulse fresh to strong at night downwind of the Papagayo region through Sun night and into next week. Seas will subside to 4-6 ft between Ecuador and the Galapagos Islands by tonight. REMAINDER OF THE AREA...Updated See the Special Features section for more information on both Hurricane Frank and on Tropical Storm Georgette. A broad swath of fresh to strong south to southwest winds is feeding into Frank from 06N to 13N between 114W-125W as was clearly evident in the 1725 UTC ASCAT data pass. Seas with these winds are in the 8-12 ft range. Otherwise, broad high pressure ridging is present N of about 19N and W of 125W. Winds are light and variable N of 22N between 118W-125W, while mainly moderate NE winds are noted under the influence if the ridge. Seas remain at 4-7 ft based on the latest altimeter data passes, with highest seas remaining across the west-central waters and N of the monsoon trough. For the forecast, mainly moderate or weaker winds are expected across the area for the next few days outside of Frank and Georgette. Expect winds and seas to increase east of 125W through the rest of the weekend as Hurricane Frank moves northwestward. The leading edge of 8 ft seas associated with Frank is currently reaching 20N, and it is forecast to reach 24N by tonight. Fresh to strong winds associated with the outer periphery of Frank will continue to affect the outer forecast waters between Cabo San Lazaro and Los Cabos through early Sun. Long-period southerly swell over the far southern waters, mainly south of the equator between 108W-120W will continue through Sun, but decay on Mon. $$ Aguirre
