Hurricane OTIS

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
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.
