Hurricane Franklin Forecast Discussion Number 13
2017-08-09 22:41:49| National Hurricane Center (Atlantic)
Issued at 400 PM CDT Wed Aug 09 2017 000 WTNT42 KNHC 092041 TCDAT2 Hurricane Franklin Discussion Number 13 NWS National Hurricane Center Miami FL AL072017 400 PM CDT Wed Aug 09 2017 Hurricane Hunter aircraft observations from earlier today indicated that Franklin was very close to hurricane strength. Since the time of the last mission, the system has become better organized, with a faint eye occasionally making an appearance on visible satellite images. Dvorak intensity estimates from both TAFB and SAB are 65 kt and this value will be used for the advisory intensity, making Franklin the first hurricane of the season. There is some northerly shear evident over the system and with several arc clouds evident over the outer circulation's northwest quadrant, perhaps some dry air is nearby. These environmental conditions are not expected to be detrimental enough, however, to prevent at least some additional strengthening before landfall tonight. An Air Force Hurricane Hunter aircraft is scheduled to investigate Franklin a few hours from now to check the strength of the cyclone. The hurricane continues to move westward, with the initial motion estimated to be 270/10. There are essentially no changes to the track forecast or reasoning. The flow on the southern side of a mid-level high pressure area near the Texas coast should continue to steer Franklin towards, and across, the southwest Gulf coast of Mexico. The official track forecast follows the latest dynamical track model consensus.

SUMMARY OF 400 PM CDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...20.1N 94.9W ABOUT 175 MI...280 KM ESE OF TUXPAN MEXICO ABOUT 105 MI...170 KM NE OF VERACRUZ MEXICO MAXIMUM SUSTAINED WINDS...75 MPH...120 KM/H PRESENT MOVEMENT...W OR 270 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...984 MB...29.06 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * The coast of Mexico from Puerto de Veracruz to Cabo Rojo A Hurricane Watch is in effect for... * The coast of Mexico north of Cabo Rojo to Rio Panuco A Tropical Storm Warning is in effect for... * The coast of Mexico east of Puerto de Veracruz to Puerto Dos Bocas * The coast of Mexico north of Tuxpan to Barra del Tordo A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion. A Hurricane Watch means that hurricane conditions are possible within the watch area. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 400 PM CDT (2100 UTC), the center of Hurricane Franklin was located near latitude 20.1 North, longitude 94.9 West. Franklin is moving toward the west near 12 mph (19 km/h), and this general motion is expected to continue for the next day or so. On the forecast track, the center of Franklin is expected to cross the coast in the Mexican state of Veracruz tonight or early Thursday. Maximum sustained winds have increased to near 75 mph (120 km/h) with higher gusts. Some additional strengthening is expected until the center crosses the coast. Rapid weakening is expected after landfall in Mexico. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). The estimated minimum central pressure is 984 mb (29.06 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Rainfall totals of 4 to 8 inches with isolated maximum amounts of 15 inches are possible across the Mexican states of Tabasco, northern Veracruz, northern Puebla, Tlaxacala, Hidalgo, Queretar and eastern San Luis Potosi in eastern Mexico. These rains will be capable of producing life-threatening flash floods and mudslides. WIND: Hurricane conditions are expected to reach the coast within the Hurricane Warning area tonight. Preparations to protect life and property should be rushed to completion. Tropical storm conditions are expected across portions of the Tropical Storm Warning area along the southern shore of the Bay of Campeche through tonight. Hurricane conditions are possible within the Hurricane Watch area tonight. Tropical storm conditions are expected within the Tropical Storm Warning area in eastern Mexico by this evening. STORM SURGE: A dangerous storm surge will raise water levels by as much as 4 to 6 feet above normal tide levels along the immediate coast near and to the north of where the center makes landfall in the Hurricane Warning area. Near the coast, the surge will be accompanied by large and destructive waves. NEXT ADVISORY ------------- Next intermediate advisory at 700 PM CDT. Next complete advisory at 1000 PM CDT. $$ Forecaster Pasch
