Super typhoon Nida

[Helge Tuschy]

Hi,

despite the fact that latest JTWC warning rates this storms as a strong 125kt typhoon, Nida is now clearly a super typhoon and probably one of the strongest systems ever observed. Dvorak classification now up to 7.5 with temporarily (not adjusted) values up to 8.0!
It looks like that the next update could rate Nida as a 155kt storm with a pressure somewhere down to 880hPa or below (latest ratings show values of 874-879hPa). A values of 878hPa or below would be needed for a top-ten rating, but let's see what the official rating will be later-on. I think the limited appearance (pattern) was one reason for somewhat lower numbers, but otherwise this system has a perfect appearance with a min/max pixel difference of well above 100°C at the center and adjacent areas.

latest JTWC has SuperTyphoon Nida at 150 knots or 173 mph sustained 1 min. average with a forecast peak at 155 knots. JTWC was way behind the satellite techniques which were giving 150 kt+ 12 hours ago.

Nida is traversing between Guam and Yap. The southern road here near Merizo, Guam was underwater late this afternoon. (We are 14 hours ahead of Eastern time zone.) Waves were huge along the SE Coast of Guam today. I went from dry to knee deep water in a matter of seconds but my cam was on a tripod so it's ok. Should be some big waves early tomorrow on the west side of Guam.

JMA, the official RSMC out here in Wpac currently have Nida at 115kts (10 min) with central pressure of 905hPa which is equal to TY Jangmi last year.

Nida is one hell of a storm. Be wary of using the pressures displayed by NRL, they are automatically generated and often way off.

Hi,

JTWC now has a 160kt super typhoon (gusts up to 195 kt) . Pressure is kept above 900 hPa (offical one), which is a bit strange for me. DT now near 7.8 with estimated pressure below 870 hPa (the magic line ). However I don't get the point why to stick with a 900 + hPa despite the necessary adjustment. Otherwise this remains an impressive storm in all available remote sensing data!

Cheers, Helge

I wonder what Fujita would of thought of the 10 min. wind average for a tornado???

Good day all,

WPAC is kicking AZN butt this year!

Too bad it's all 99.9% "water" out there...

Horseshoes, hand grenades, and island tropical cyclone chasing.

Sure is a lot of water spawning up some real monsters.

There have been 22 storms this year, of which 16 made landfall, or passed close enough to populated areas to make their presence felt. The average number of named storms by now is 25 so it's actually quite a quiet year at the moment!

Day 4 of Supertyphoon Nida. The Northwest Pacific rocks all the way to January.
