Typhoon pressures since 1987 (post recon era)
Recon flights into typhoons ended in the middle of the 1987 season. However, low barometric pressures have still been recorded by weather stations, buoys, ships, etc.
Although not as impressive as the pressures measured by recon, some of the pressures are still impressive. There's no doubt some of these storms had lower pressures than were recorded.
I'll list typhoons that had a recorded pressure of 970mb or lower.

Megi was measured at 890hPa by a dropsonde and that was before it was quite at its peak hence the 885hPa in the following advisories.

Bill,
You have spent a lot of time compiling this data and I appreciate it. Good job!
However, can you possibly identify what recorded those pressures? I mean was it a buoy and if possible the date(s)? Or was it a land station?
I know they estimate a lot from satellite imagery and peripheral synoptic reports from the islands. So, precise pressures in these WestPac cyclones appear to be a thing of the past since recon stopped nearly a quarter century ago. Obviously there are going to be a few rare instances in which a cyclone will directly go over an island or land station and we will have direct and accurate information on pressure as well as winds, but I was hoping if you have time you could add the date(s) those pressures (and time if possible) as well as the recording source. Was it a buoy or a ship report? Was it a land station? If I knew the source and the site of the met station would help me understand if this was the minimum pressure of the cyclone or whether the pressure was outside the eye thereby meaning the actual minimum pressure could be extrapolated or estimated based on distance and wind speed. I hope that made sense.
Good job though! I truly appreciate your hard work and your efforts! Have a good weekend!
David

Re: Typhoon pressures since 1987 (post recon era)
amazing to see those super typhoons that got penetrated by recon peak near 900 mb or lower while others estimated are way too high. imagine if all of them got penetrated...

Re: Typhoon pressures since 1987 (post recon era)
Great stuff Bill! We're so very lucky that recon flew into Megi!
I believe Shanshan had measured 919hPa on Iriomote island in 2006. Unusual for JMA to have a peak pressure not divisible by 5. Wish I was there for that one:

Re: Typhoon pressures since 1987 (post recon era)
List of events with recorded MSLP below 940 hPa
1987
Super Typhoon Nina - 909.5 hPa (Recorded by Station in Legazpi City, Albay) - current national record low in Philippines
2005
Typhoon Longwang - 924.5 hP a (interpolated based on data gathered by a UAV "Aerosonde"
2012
Typhoon Bolaven - 934.3 hPa - Reported by a station in Nago, Okinawa
Super Typhoon Sanba - 939.4 hPa - Reported by a station in Nago, Okinawa
2013
Super Typhoon Usagi - 922.7 hPa - recorded at Basco Radar site
Super Typhoon Haiyan - 910 hPa* - recorded by station in Guiuan Samar - *this is station pressure
2014
Super Typhoon Rammasun - 899.2 hPa - recorded by an AWS in Quizou Island
2015
Super Typhoon Soudelor - 939 hPa - recorded in Saipan during the passage of the typhoon's extremely small micro eye
2016
Super Typhoon Nepartak - 911.5 hPa - recorded by NTU 2 Buoy near Orchid island
"We have recovered the barometer at NTU2 during a buoy service cruise in early August and sent it to the Taiwan's Central Weather Bureau for calibrating the pressure sensor. After a carefully calibration procedure, we corrected the pressure data and obtained the lowest atmospheric pressure of 911.5 hPa instead of 897 hPa when the center of Nepartak was the closest to NTU2.”
Super Typhoon Meranti - 877.9 hPa? (unverified) - recorded by a DOST-ASTI Automatic Weather Station (AWS) at Itabayat Municipal Hall. A 1700z SYNOP from Itbayat Station reported 933.6 hPa followed by a mysterious 983 hPa reading at 1800z (which is believed by some as an error and suggested that it's actually 883 hPa?)
Typhoon Malakas - 936.9 hPa - recorded by station in Yonagunijima
2017
Super Typhoon Lan - 925 hPa - observed via dropsonde by a rare eye penetration by Japanese reconnaissance (T-PARCII)
2018
Super Typhoon Trami - 918.8 hPa - observed via dropsonde (T-PARCII)
Super Typhoon Mangkhut - 936.2 hPa - measured by an AWS in Gattaran, Cagayan Province despite being way inland from the landfall point.
Super Typhoon Yutu - 921.7 hPa - eyewall pressure recorded by a barometer set up by Dr. Mark Lander in Saipan
2020
Super Typhoon Haishen - 919 hPa - recorded by a buoy
Super Typhoon Goni - 912.1 hPa - recorded by manned station in Virac, Catanduanes
2021
Super Typhoon Chanthu - 927.8 hPa - recorded at the Basco Synoptic Station (98134)
Super Typhoon Mindulle - 932.4 hPa - recorded via dropsonde by a reconnaissance mission of Nagoya University / University of the Ryukyus (T-PARCII)

Re: Typhoon pressures since 1987 (post recon era)
Very generic question, but is there a reason why the WPAC mets do not fly recon into typhoons?

Re: Typhoon pressures since 1987 (post recon era)
Ok so there was this recon mission into Typhoon Jangmi 2008 that measured... 901mb I think? something like that
can anyone do me a favor and link me to a source for that?

I think 901 hPa was extrapolated.
the one stated on the VDM was 906 hPa
