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. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 300 AM CST (0900 UTC), the center of Tropical Storm John was located near latitude 14.4 North, longitude 98.5 West. John is moving toward the north-northeast 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 during the next day or two and move inland on Tuesday or Wednesday. Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. John is forecast to strengthen over the next day or two, and could become a hurricane before landfall. Tropical-storm-force winds extend outward up to 35 miles (55 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 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_ep10.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 possible early Tuesday within the Hurricane Watch area. Tropical storm conditions are expected to start within portions of the warning area late today or early Tuesday. Tropical storm conditions are possible within portions of the watch area beginning on Tuesday. SURF: Swells associated with John are forecast to begin to affect the coast of southern Mexico later today, 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 AM CST. Next complete advisory at 900 AM CST. $$ Forecaster Blake

Atlantic Tropical Weather Outlook
2024-09-23 07:43:27| National Hurricane Center (Atlantic)
000 ABNT20 KNHC 230543 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Mon Sep 23 2024 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Northwestern Caribbean Sea and Gulf of Mexico (AL97): Showers and thunderstorms are beginning to show signs of organization with a broad area of low pressure located over the northwestern Caribbean Sea. Environmental conditions appear favorable for further development of this system, and a tropical depression or storm is likely to form over the next couple of days as the system moves northward across the northwestern Caribbean Sea and into the southeastern Gulf of Mexico where additional development is possible. Regardless of development, this system is expected to produce heavy rains over portions of Central America during the next several days. Interests in the northwestern Caribbean, the Yucatan Peninsula of Mexico, and western Cuba should closely monitor the progress of this system. Later this week, the system is forecast to move generally northward across the eastern Gulf of Mexico, and interests along the northern and northeastern Gulf Coast should also closely monitor the progress of this system. * Formation chance through 48 hours...high...70 percent. * Formation chance through 7 days...high...90 percent. Eastern and Central Tropical Atlantic: A tropical wave located between western Africa and the Cabo Verde Islands is producing disorganized shower and thunderstorm activity. Environmental conditions appear generally favorable for gradual development of this system, and a tropical depression is likely to form during the middle to latter part of this week while it moves westward to west-northwestward across the eastern and central tropical Atlantic. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...high...70 percent. $$ Forecaster Papin
