The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...SPECIAL FEATURES... Hurricane Fausto is centered near 17.5N 123.0W at 23/0300 UTC, moving west-northwest at 7 kt. Estimated minimum central pressure is 982 mb. Maximum sustained wind speed is 70 kt with gusts to 85 kt. Peak seas are near 30 ft. Numerous moderate to scattered strong convection is occurring within 120 nm of center. Scattered to numerous moderate isolated strong convection is noted elsewhere from 13.5N to 21N between 116.5W and 124W. Fausto is moving west-northwestward over open waters, with a continued west-northwestward to westward motion expected to continue through the weekend, along with an increase in forward speed beginning later tonight or Thu. Some gradual strengthening is possible through the next 36 hours, followed by slow weakening on Friday and into the weekend. Swells generated by Fausto are affecting portions of the west coast of the Baja California Peninsula and are spreading northward toward the coast of southern California. These swells are likely to cause life- threatening surf and rip current conditions. Please consult products from your local weather office. Please read the latest HIGH SEAS FORECAST issued by the National Hurricane Center at website - https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest Fausto NHC Forecast/Advisory and Public Advisory at www.hurricanes.gov for more details. Eastern and Central East Pacific: A tropical wave with axis along 93W continues to move into a large area of disorganized showers and thunderstorms occurring about the monsoon trough across the tropical eastern Pacific. Gradual organization of this system is expected, and a tropical depression is likely to form over the weekend while it moves generally west- northwestward at 10 to 15 mph, remaining well offshore of Mexico. The latest Tropical Weather Outlook gives this system a medium chance of tropical cyclone formation through 48 hours, and a high chance through 7 days. Please, refer to the latest NHC Tropical Weather Outlook at www.hurricanes.gov ...TROPICAL WAVES... A tropical wave is along 93W N of 05N extending into western Guatemala, moving westward near 10 kt. Associated convection is described below. Please, see the Special Features section for more information related to this wave. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from near 10N75W to 08.5N92W to 07.5N101W to 10N114W, then resumes SW of Fausto from 13N126W to beyond 09N140W. Scattered to locally numerous moderate isolated strong convection is noted from 03N to 11.5N E of 119W to the coast of Colombia. Scattered moderate convection is noted from 06N to 11.5N W of 137W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please refer to the Special Features section for details on Hurricane Fausto, centered about 800 nm WSW of the southern tip of Baja California. Fausto continues to move westward and away from the Revillagigedo Islands, allowing high pressure to build in across the offshore waters of Baja California and to the Revillagigedos. This pattern is producing leaving gentle to moderate NW to N winds and seas of 6 to 7 ft in W swell across those area waters. A ridge continues to build between Hurricane Fausto and the Baja California Peninsula. Late afternoon satellite scatterometer data indicated fresh to locally strong NW winds north of Punta Eugenia, and moderate to locally fresh NW to N winds between Punta Eugenia and Cabo San Lucas. S to SW swell generating by Fausto is spreading across the area, and mixing with the building northerly wind waves to produce seas 6 to 8 ft across the Baja waters, highest N of Punta Eugenia. Gentle to moderate NW to W winds and moderate seas prevail across the remainder of the Mexican offshore waters, except for fresh to strong N gap winds across the Tehuantepec region and downwind to about 15N. For the forecast, as Hurricane Fausto continues to move westward and away from the offshore waters, high pressure will build across the Baja California offshore waters through Thu night. The pressure gradient between the ridge and a meandering trough over the Gulf of California will support fresh to strong NW winds and building seas N of Punta Eugenia through Thu night into Fri morning. Swells generated by Fausto will persist through Thu before fading. These swells are likely to cause life- threatening surf and rip current conditions. Please consult products from your local weather office. In the Gulf of California, mainly gentle to moderate southerly winds are expected, increasing to fresh speeds Fri night through Sat night. Fresh northerly winds are forecast in the Tehuantepec region during the overnight and early morning hours through the week, with locally rough seas. Please refer to the Special feature section for details on the next tropical cyclone forecast to develop well offshore of Mexico over the upcoming weekend. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Afternoon satellite scatterometer wind data show fresh to strong N to E winds continuing across the Papagayo region and extending downwind to near 90W, and northward to northwestern Nicaragua. Seas are 5 to 7 ft with these winds based on altimeter data. This is occurring behind a tropical wave with axis along 93W. The monsoon trough remains active across the offshore waters, producing scattered to locally numerous convection N of 06N. Elsewhere, winds are moderate or weaker with seas 4 to 5 ft in S to SW swell. For the forecast, fresh to strong NE to E winds and moderate to rough seas will persist across the Papagayo region through Thu, then mainly moderate to fresh winds are expected. Gentle to moderate N winds are forecast in the Gulf of Panama with slight to moderate seas. Moderate or weaker winds and moderate seas in SW swell will prevail elsewhere. Seas, associated with a broad area of low pressure currently located along the monsoon trough, may impact the offshore waters of Guatemala and El Salvador Thu through Fri, building seas to 6 to 8 ft. ...REMAINDER OF THE AREA... Please refer to the Special Features section for details on Hurricane Fausto, centered about 800 nm WSW of the southern tip of Baja California. Hurricane Fausto dominates conditions over the High Seas forecast waters roughly from 12N to 23N between 118W and 127W. Fresh to strong winds outside of the immediate circulation of Fausto extend northward to 23N, with seas to 8 ft reaching as far N of Fausto as 26N. Elsewhere, a ridge dominates the waters between Baja California and Fausto, and also N of 15N W of 125W. Moderate or weaker winds with moderate to rough seas prevail. For the forecast, Hurricane Fausto will move to 17.7N 124.7W Thu morning, 18.0N 127.4W Thu afternoon, 18.3N 130.1W Fri morning, 18.6N 132.8W Fri afternoon, 18.9N 135.4W Sat morning, and 19.2N 137.8W Sat afternoon. Fausto will change little in intensity as it moves to near 19.9N 142.6W Sun afternoon. Please refer to the Special feature section for details on the next tropical cyclone forecast to develop well offshore of Mexico over the upcoming weekend. Strong cross-equatorial swell will begin to move into the area Wed night and slowly build Thu night through the weekend. $$ Stripling ########################### END OF MESSAGE SET ############################
