DISCUSSION AND OUTLOOK ---------------------- At 900 AM CST (1500 UTC), the center of Tropical Storm John was located near latitude 14.8 North, longitude 98.5 West. John is moving toward the north near 3 mph (6 km/h). A slow motion to the north-northeast or northeast is expected for the next couple of days. On the forecast track, the center of the system is forecast to approach the southern coast of Mexico late tonight and early Tuesday, and move inland on Tuesday or Tuesday night. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Rapid strengthening is forecast, and John is expected to become a hurricane by this afternoon, with additional strengthening expected before the center reaches the coast of southern Mexico. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure is 992 mb (29.30 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 Tropical Storm John, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_ep5.shtml?rainqpf STORM SURGE: A dangerous 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 early Tuesday. Winds are expected to first reach tropical storm strength tonight, 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 on Tuesday. 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.
