All power lost nearby about 10m ago. All it is picking up is the occasional lightning flash from the eyewall. Link to comment Share on other sites More sharing options...

Floydbuster Posted October 25, 2023 Share Posted October 25, 2023 Hurricane Otis is the strongest hurricane to strike the Pacific coastline of Mexico on record, and the only one to make landfall at Category 5 intensity. 2 Link to comment Share on other sites More sharing options...

Roger Smith Posted October 25, 2023 Share Posted October 25, 2023 Acapulco's max daily rainfall was 16.9" in October 1997 from a weaker 'cane (Pauline); nearby locations recorded 25-35 in rainfalls. Results were destructive flooding and a toll of about 300 dead in Guerrero state. NWS says 12-20 in rains from Otis but I would imagine looking at satellite and terrain, 15-35 could be more realistic. Pauline in 1997 did not bring strong winds, max gusts at Acapulco were TS range. No doubt 2023 will be a worse outcome by far. Link to comment Share on other sites More sharing options...

Radtechwxman Posted October 25, 2023 Share Posted October 25, 2023 Looks like eye started to fill right before landfall. May have weakened ever so slightly probably from land interaction with mountainous terrain. But NHC called it a 165mph landfall 1 Link to comment Share on other sites More sharing options...
Normandy Posted October 25, 2023 Share Posted October 25, 2023 Considering the extreme wind damage and short duration of max winds because of the small size of the core, I see no issue with the 165 mph landfall. There is likely a chance it was even more intense just offshore before the eye started filling. Are there any pressure readings from landfall? 1 Link to comment Share on other sites More sharing options...

Windspeed Posted October 25, 2023 Author Share Posted October 25, 2023 The eye fill was right at landfall. Yes, you have to take into account parallax. You also have to attribute eyefill most likely to the rugged terrain that immediately began disrupting the core at landfall. But as they say, too little too late. No doubt it was a Cat 5 landfall to me. 1 Link to comment Share on other sites More sharing options...

Roger Smith Posted October 25, 2023 Share Posted October 25, 2023 Sounds like a fairly good response given lack of lead time, reportedly 8,000 military personnel sent to region just before landfall to co-ordinate expected rescue and recovery work, and numerous emergency locations, I would imagine news spread fairly fast among well connected people but not among a large segment of poorer residents. Looked up metars for Acapulco but last one was before landfall around 0330z. So far a general lack of reports, would expect severe impacts, areas to west along coast would be getting stream overflow from torrential rainfalls no doubt experienced for most of region. Looks like Acapulco city is fairly rolling (flatter areas east) and ravines from nearby mountains would likely become debris torrent filled quickly after landfall. In 1997 I read reports of meter-deep sewage filled mudflows running down streets. If you look on google map view, you can see evidence of normal conditions including piles of garbage and debris on residential streets. All of it now floating around on its way into Pacific Ocean.

If well constructed commercial establishments have people inside hiding from the wind……you know the wind is bad. Only cat 5 winds can do that. You can best believe low-rise wood framed buildings got shredded by this. Link to comment Share on other sites More sharing options...
