DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Post-Tropical Cyclone Karl was located near latitude 18.6 North, longitude 93.0 West. The post-tropical cyclone is moving toward the southwest near 5 mph (7 km/h). A southwestward to west-southwestward motion is expected today, and the center of the low should move along the coast of southern Mexico this morning, and inland by later today. Maximum sustained winds have decreased to near 30 mph (45 km/h) with higher gusts. Additional weakening is forecast, and the low is expected to dissipate tonight. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for the system can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at hurricanes.gov/MIATCDAT4.shtml RAINFALL: The remnants of Karl are expected to produce 2 to 5 inches of rain, with local maxima up to 8 inches, across portions of Veracruz, Tabasco, and northern Chiapas and Oaxaca states in Mexico through Sunday morning. These rains could produce flash flooding, along with mudslides, in higher terrain. SURF: Swells generated by this system are expected to affect the Mexican coastline through tonight. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system. For additional information on heavy rainfall and flooding, please see products issued by your national meteorological service. $$ Forecaster Brown

679 WTNT44 KNHC 150847 TCDAT4 Post-Tropical Cyclone Karl Discussion Number 16 NWS National Hurricane Center Miami FL AL142022 400 AM CDT Sat Oct 15 2022 Moderate to strong vertical wind shear and relatively low mid-level humidities have continued to take a toll on Karl. Satellite data and radar imagery from Mexico indicate that the cyclone has not produced any organized deep convection since around midday yesterday, and it is very unlikely any will return this morning. Therefore, Karl has become a remnant low and this will be the last NHC advisory on this system. The radar imagery has revealed a persistent area of showers and thunderstorms with heavy rainfall well south of Karl's center that appears to be related to upslope flow against the mountainous terrain of southern Mexico. Within this cluster of convection, a significant amount of lightning has been noted in the GOES Lightning Mapper (GLM) data overnight. Karl's remnants could still produce flash flooding and mudslides over portions of southern Mexico through this weekend. The initial intensity has been reduced to 25 kt, which is a blend of Dvorak T- and CI-numbers from TAFB and SAB. The global models indicate that the remnant low will continue to spin down today, and the official forecast calls for it to become a trough of low pressure by tonight when it moves inland over southern Mexico. The low is currently moving southwestward at about 4 kt, and a southwestward to west-southwestward motion should continue until dissipation occurs. This motion should bring the center of the cyclone along the southern coast of the Bay of Campeche this morning, and inland by later today. This is the last NHC advisory on this system. For additional information on heavy rainfall and flooding, please see products issued by your national meteorological service. Key Messages: 1. Heavy rainfall associated with the remnants of Karl could produce instances of flash flooding, with mudslides in areas of higher terrain, across portions of Veracruz, Tabasco, Chiapas and Oaxaca states in Mexico.
