ZCZC MIATCDEP3 ALL TTAA00 KNHC DDHHMM Hurricane Otis Discussion Number 12 NWS National Hurricane Center Miami FL EP182023 1000 PM CDT Tue Oct 24 2023 A nightmare scenario is unfolding for southern Mexico this evening with rapidly intensifying Otis approaching the coastline. Satellite images show that Otis has continued to intensify, with Dvorak Data-T estimates between 130-145 kt during the past few hours. The initial wind speed is set to 140 kt as a blend of these values, making Otis a Category 5 hurricane. Otis has explosively intensified 95 kt during the past 24 hours, a mark only exceeded in modern times by Patricia in 2015. Otis should maintain category 5 status before the hurricane makes landfall near the Acapulco area overnight or early on Wednesday. The only significant change to mention to the track forecast is that it has been shifted to the right due to a recent wobble to the east and the latest model trends, and a general north-northwest motion at about 8 kt is anticipated through landfall. Rapid weakening is anticipated after landfall, and Otis should dissipate tomorrow night over the higher terrain of Mexico. This is an extremely serious situation for the Acapulco metropolitan area with the core of the destructive hurricane likely to come near or over that large city early on Wednesday. There are no hurricanes on record even close to this intensity for this part of Mexico. Key Messages: 1. Otis is forecast to be a potentially catastrophic Category 5 hurricane when it reaches the southern coast of Mexico early Wednesday. Life-threatening hurricane-force winds are expected in portions of the Hurricane Warning area with catastrophic damage expected. 2. A potentially catastrophic storm surge is expected to produce life-threatening 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. 3. Heavy rains from Otis will continue to impact areas of southwest Mexico this week. This rainfall will produce flash and urban flooding, along with mudslides in areas of higher terrain.
