DISCUSSION AND OUTLOOK ---------------------- At 300 PM CST (2100 UTC), the center of Hurricane John was located near latitude 15.5 North, longitude 98.5 West. John is moving toward the north near 6 mph (9 km/h). A slow motion to the north or north-northeast is expected during the next 24 hours. On the forecast track, the center of John is forecast to move inland along the coast of southern Mexico tonight or early Tuesday. Maximum sustained winds have increased to near 100 mph (155 km/h) with higher gusts. John is a category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. Rapid strengthening is forecast to continue, and John is expected to become a major hurricane as it approaches the coast of southern Mexico. 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 973 mb (28.74 inches). HAZARDS AFFECTING LAND ---------------------- Key Messages for John can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC and on the web at hurricanes.gov/text/MIATCDEP5.shtml RAINFALL: Through Thursday, John is expected to produce 6 to 12 inches of rain with isolated totals around 15 inches across the coastal areas of Chiapas. In areas along and near the Oaxaca coast to southeast Guerrero, between 10 and 20 inches of rain with isolated totals near 30 inches can be expected through Thursday. This heavy rainfall will likely cause significant and possibly catastrophic, life-threatening flash flooding and mudslides to the Mexican States of Chiapas, Oaxaca, and southeast Guerrero, particularly in areas near the coast. For a complete depiction of forecast rainfall associated with Hurricane John, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_ep5.shtml?rainqpf STORM SURGE: A life-threatening storm surge is expected to produce significant coastal flooding near and to the east of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. WIND: Hurricane conditions are expected to reach the coast within the hurricane warning area tonight. Winds are expected to first reach tropical storm strength later this afternoon, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Tropical storm conditions are expected to first reach the coast within the tropical storm warning area this evening. SURF: Swells associated with John are forecast to continue affecting the coast of southern Mexico during the next couple of days, with the potential for dangerous surf and rip currents much of the week. Please see local statements for more information. NEXT ADVISORY ------------- Next intermediate advisory at 600 PM CST. Next complete advisory at 900 PM CST. $$ Forecaster Hagen
