Hurricane Katia Public Advisory Number 5A

2017-09-07 01:46:18| National Hurricane Center (Atlantic)

Issued at 700 PM CDT Wed Sep 06 2017 000 WTNT33 KNHC 062346 TCPAT3 BULLETIN Hurricane Katia Intermediate Advisory Number 5A NWS National Hurricane Center Miami FL AL132017 700 PM CDT Wed Sep 06 2017 ...KATIA MOVING LITTLE IN THE SOUTHWESTERN GULF OF MEXICO... SUMMARY OF 700 PM CDT...0000 UTC...INFORMATION ---------------------------------------------- LOCATION...21.7N 94.9W ABOUT 195 MI...315 KM E OF TAMPICO MEXICO ABOUT 190 MI...310 KM NNE OF VERACRUZ MEXICO MAXIMUM SUSTAINED WINDS...75 MPH...120 KM/H PRESENT MOVEMENT...SE OR 135 DEGREES AT 3 MPH...6 KM/H MINIMUM CENTRAL PRESSURE...992 MB...29.30 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Watch is in effect for... * Tuxpan to Laguna Verde A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 PM CDT (0000 UTC), the center of Hurricane Katia was located near latitude 21.7 North, longitude 94.9 West. Katia is moving toward the southeast near 3 mph (6 km/h). Little overall motion is anticipated through tonight, but a southwestward drift should begin tomorrow. Maximum sustained winds remain near 75 mph (120 km/h) with higher gusts. Some additional strengthening is forecast during the next 48 hours. Katia is a small tropical cyclone. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm- force winds extend outward up to 60 miles (95 km). The estimated minimum central pressure is 992 mb (29.30 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Katia is expected to produce total rain accumulations of 5 to 10 inches over northern Veracruz, and 2 to 5 inches over far southern Tamaulipas, northeast Puebla, and southern Veracruz through Saturday morning. Isolated maximum amounts of 15 inches are possible in northern Veracruz. This rainfall may cause life-threatening flash floods and mudslides, especially in areas of mountainous terrain. WIND: Hurricane conditions are possible within the watch area by late Friday, with tropical storm conditions possible earlier that day. SURF: Swells generated by Katia are expected to affect portions of the coast of southeastern Mexico tomorrow. 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 1000 PM CDT. $$ Forecaster Blake
