SUMMARY OF 100 PM CDT...1800 UTC...INFORMATION ---------------------------------------------- LOCATION...21.6N 94.6W ABOUT 215 MI...345 KM E OF TAMPICO MEXICO ABOUT 195 MI...315 KM NNE OF VERACRUZ MEXICO MAXIMUM SUSTAINED WINDS...80 MPH...130 KM/H PRESENT MOVEMENT...STATIONARY MINIMUM CENTRAL PRESSURE...980 MB...28.94 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Cabo Rojo to Laguna Verde A Tropical Storm Warning is in effect for... * North of Cabo Rojo to Rio Panuco * South of Laguna Verde to Puerto Veracruz. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical- storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 100 PM CDT (1800 UTC), the center of Hurricane Katia was located near latitude 21.6 North, longitude 94.6 West. Katia is stationary and little overall motion is anticipated through late today. However, the hurricane is forecast to turn west-southwestward and approach the coast within the warning area late Friday or early Saturday. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Some strengthening is forecast during the next 36 hours and Katia could be near major hurricane strength at landfall. Katia is a small tropical cyclone. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 45 miles (75 km). The estimated minimum central pressure is 980 mb (28.94 inches). HAZARDS AFFECTING LAND ---------------------- STORM SURGE: A dangerous storm surge will raise water levels by as much as 5 to 7 feet above normal tide levels near and to the north of where Katia makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Katia is expected to produce total rain accumulations of 10 to 15 inches over northern Veracruz and eastern Hidalgo, Puebla, and San Luis Potosi. Katia is expected to produce total rain accumulations of 2 to 5 inches over southern Tamaulipas, central San Luis Potosi, western Hidalgo, eastern Queretaro, and southern Veracruz through Saturday evening. Isolated maximum amounts of 25 inches are possible in northern Veracruz and eastern Hidalgo, Puebla, and San Luis Potosi. This rainfall may cause life- threatening flash floods and mudslides, especially in areas of mountainous terrain. WIND: Hurricane conditions are expected within portions of the hurricane warning area by Friday night or early Saturday, with tropical storm conditions expected within the tropical storm warning areas by late Friday. SURF: Swells generated by Katia are expected to affect portions of the coast of southeastern Mexico today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 400 PM CDT. $$ Forecaster Pasch

Hurricane Katia Forecast Discussion Number 8
2017-09-07 16:32:47| National Hurricane Center (Atlantic)
Issued at 1000 AM CDT Thu Sep 07 2017 000 WTNT43 KNHC 071432 TCDAT3 Hurricane Katia Discussion Number 8 NWS National Hurricane Center Miami FL AL132017 1000 AM CDT Thu Sep 07 2017 An Air Force Hurricane Hunter aircraft found that the central pressure had dropped to 982 mb and maximum SFMR-observed surface winds were close to 70 kt. Therefore 70 kt will be retained for the current intensity. Vertical wind shear should remain low over the southwest Gulf of Mexico for the next couple of days and the global models show well-developed upper-level outflow over the tropical cyclone. Thus, further strengthening is likely up to landfall. The official intensity forecast is somewhat higher than the model consensus and Katia could approach major hurricane status before it crosses that coast. Fixes from the Hurricane Hunter aircraft show essentially no motion over the last several hours. A mid-level ridge is likely to build to the north of Katia during the next day or so. This should induce a west-southwestward motion beginning tonight or early Friday, leading to landfall by late Friday or early Saturday. The official track forecast is similar to the previous one and close to the model consensus.
