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.

I’m squarely in late fall mode and will do a review of my peak season forecast soon but it looks like there’s some higher end potential in the Caribbean in the next two weeks.
I know I’m in the minority, but given the epic blowtorches we’ve seen recently—including all of last January—I found the near Christmas blast and Montreal Express in February to be awesome.
Again in the minority here, but winters here are far too fickle to put snow as the only thing worth caring about. That’s a recipe for misery. Of course snow is first, but I’ll take any winter—ice, pingers, and cold, especially big dog cold.
I was just coming in to post. It’s all time RI in that part of the basin and an all time bust. Broke the RI record from Patricia and the 24 hour forecast from models were dangerously horrific.
I know from personal experience that the ones you miss haunt you as much if not more than the joy that comes with the successful chases.
I was in Hartford for that one. Moved to DC in late 2013. All timer.
Lived in DC for a lot of those. Moved back to CT after that 2017-18 season
Another big dog will arrive eventually. I really just want to see a classic megalopolis mauler that makes everyone happy.
Impressive in its own right.
This isn't all in SNE but since 2013-14 I personally can only recall 12+ imby from 12/16/20 and the 2016 Blizzard when I lived in DC. Maybe one got close in that epic 2013-14 season in DC. That remains my favorite winter.
Climo makes cold just about useless through at least the first third to half of December too…
There’s nothing wrong with normal. That’s about a 61 high/40 low here. Today is glorious. Crisp morning and beautiful afternoon.
