WPAC: YUTU - Post-Tropical

[Highteeld]

Looking a little more organized right now.

[mrbagyo]

Getting a boost from trough interaction.
Looking pretty good

[1900hurricane]

Looks to be quickly dissipating now.

[1900hurricane]

How the mighty have fallen.

Assessment found Super Typhoon Yutu brought gusts up to 200 mph

Yutu’s satellite intensity estimate peaked at 178 mph as a Category 5 storm just prior to landfall over Tinian and the southern half of Saipan, the assessment states. That value seems to establish the upper limit of the maximum intensity while over the islands.

All official ground-based instrumentation failed on Tinian and Saipan as the winds in the storm surged well-above 100 mph, the release states.

A more complete and detailed report on the findings of the Yutu Meteorological Assessment Team, along with additional pictures, figures and tables, will soon be posted on the WERI website at www.weriguam.org and on the WFO Guam website at www.weather.gov/GUM.

Did any pressure readings get captured? Without any other data, I would set the intensity at 150 kt.

Study: Yutu rivaled Karen

Lander was on Saipan during the passage of the typhoon and set up a rain gauge and a barometer at his location in San Vicente. All official ground-based instrumentation failed on Tinian and Saipan as the winds surged well above 100mph. The minimum pressure in San Vicente dropped to 921.7 millibars (mb), according to Lander’s findings.

After necessary adjustments, the pressure was used to estimate the minimum central surface pressure of Yutu, which was found to be somewhere in the range of 905-910 mb. His rain gauge recorded about 10 inches of rainfall during the storm, which was used to supplement the 2.66 inches of rainfall recorded up to midnight at the Francisco C. Ada/Saipan International Airport.

With that data, I'd probably keep peak intensity at 155 kt for Yutu. Using KZC and an estimated 905 mb pressure, I get about 150 kt using both JTWC and regressed JMA wind radii, and about 155 kt using JTWC's radius of the outermost closed isobar. Satellite estimates were also in the 155-160 kt range. 155 kt overlaps in both of these intensity estimate intervals as well as matches the operational estimate, so I see no reason to change it personally.

[euro6208]

Incredible. Strongest typhoon ever in Marianas history.

[Highteeld]

Downgraded to 150 knots.

[Highteeld]

Given the large size, I would have to suspect the pressure is below 900 mb right now. I would personally go with an intensity of 150 kt right now.

Strong bump/10, but this is actually what the revised JTWC best track went with XD.
