The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0345 UTC. ...SPECIAL FEATURES... Hurricane Polo is centered near 17.4N 110.1W, or about 310 nm southwest of Cabo Corrientes Mexico at 26/0300 UTC, moving west- northwest at 9 kt. Estimated minimum central pressure is 911 mb. Maximum sustained wind speed is 150 kt with gusts to 185 kt. Peak seas are 46 ft (14 m). Polo looks very impressive in satellite imagery as it remains a powerful category 5 hurricane on the Saffir- Simpson Hurricane Wind Scale. A clear 15 nm wide eye is observed. The imagery reveals that Polo has numerous strong convection within 90 nm of the center in the NE quadrant, 150 nm of the center in the SE and NW quadrants and 120 nm of the center in the SW quadrant. Polo will maintain its current motion tonight, followed by a gradual turn toward the northwest on Sat and north on Sun. By Mon, Polo is forecast to turn northeastward and approach Baja California Sur. Fluctuations in intensity are possible tonight and Sat. Slow weakening is expected after that, but Polo is expected to remain a powerful hurricane as it approaches Baja California Sur early next week. Polo is expected to produce rainfall totals of 4 to 8 inches with maximum amounts of 10 inches across portions of Baja California Sur. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain. For a complete depiction of forecast rainfall associated with Polo, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_ep2.shtml?rainqpf Swells generated by Polo will continue affecting the coast of southwestern Mexico during the next couple of days. Swells will spread northward along the coast of west-central Mexico and the Baja California Peninsula through the weekend. These swells are likely to cause life-threatening surf, rip currents, and coastal flooding. Please consult products from your local weather office. Hurricane Odalys is centered near 18.8N 123.6W, or about 810 nm west-southwest of the southern tip of Baja California at 26/0300 UTC, moving north at 4 kt. Estimated minimum central pressure is 952 mb. Maximum sustained wind speed is 105 kt with gusts to 130 kt. Peak seas are 38 ft (11.5 m). Odalys remains a powerful major hurricane, though satellite imagery is beginning to show signs of weakening. Its eye remains rather ragged. The imagery shows numerous strong convection within 120 nm of the center in the NE quadrant, 75 nm of the center in the SE quadrant, 60 nm of the center in the SW quadrant and 90 nm of the center in the NW quadrant. Odalys is expected to maintain its current motion through Sat, followed by a turn toward the northeast on Sunday. An eastward to southeastward motion is forecast early next week. Odalys is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. A weakening trend is forecast to begin tonight and continue through early next week. 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 NHC Forecast/Advisory and Public Advisory at www.hurricanes.gov for more details on both Polo and Odalys. Low pressure South of the Gulf of Tehuantepec: An area of low pressure, Invest EP90, located south of the Gulf of Tehuantepec is becoming organized. Environmental conditions are conducive for gradual development, and a tropical depression is expected to form late this weekend or early next week while the system moves slowly west-northwestward to northwestward, parallel to the coast of southern and southwestern Mexico. There is a medium chance of tropical formation within 48 hours and a high chance of tropical formation through the next 7 days. The broader circulation, deep moisture, and instability associated with this system is already producing heavy rainfall over portions of Central America and Southern Mexico. Additional rainfall amounts through Sat night across portions of Honduras, El Salvador, and Guatemala, as well as Chiapas and Oaxaca in Mexico, will raise concerns for life- threatening flash flooding and landslides. Please refer to local weather services as well as the International Desk at the Weather Prediction Center for more information. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from northwest Colombia to across the southwestern Caribbean Sea, to across northern Costa Rica, to 10N85W to 11.5N91W to Invest EP90 and to 14N99W. It resumes to the SW of Odalys at 12N127W, to 11N132.5W and to beyond 14N140W. Numerous moderate to isolated strong convection is from 02N to 10N between 129W-140W. Scattered moderate to isolated strong convection is within 120 nm south of the trough between 85W-90W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for information on Major Hurricanes Polo and Odalys as well as low pressure developing south of the Gulf of Tehunatepec that is bringing very heavy rainfall to portions of southern Mexico. Fresh northeast gap winds are in the Gulf of Tehuantepec region. Seas Latest satellite scatterometer data passes indicate gentle to moderate northwest to north winds offshore the Baja California Peninsula and light to gentle winds elsewhere over the Mexican offshore waters away from Hurricane Polo. Light to gentle winds are in the Gulf of California. Large seas in long-period southeast to south swell out ahead of Polo are impacting the offshore waters of Baja California south of about Punta Eugenia and at the entrance of the Gulf of California. Seas produced by the swell are in the range of about 8 to 12 ft. Seas of 6 to 9 ft in west to northwest are over the offshore waters of the states of Michoacna and Guerrero and seas of 5 to 7 ft in west to northwest swell are over the waters of those states. Seas of 2 to 4 ft are in the central section of the Gulf of California, 3 ft or less in the northern section and 4 to 6 ft in the southern section of the Gulf.
