Former TC Xavier in S Pac

[Cyclenall]

The current sat images show a pin-hole like eye on Xavier. By the looks of it, this is way stronger then 85 knots 1-min. Whenever that pin-hole eye such as the one on Xavier, that means the cyclone is very strong. Wilma was the best example for a tropical cyclone. The banding is also fantastic. My guess at strength is 120 knots 1-min winds.

Nice eye, and the visible is out again.

Where do I get these images?

Has there ever been a system of this strength, for this early for the south Pacific.

this is just a example of El Nino seasons in south pacific.

early start and intense storms for south pacific islands.

just I didn't think the 2 things would combine

105mph, 935mb???? That doesn't add up at all. But then again, Neither does 125mph, 920mb.

If I was blindly guessing I'd say it was about 140mph, 935mb

These are 10-min sustained winds.

10-min sustained winds of 90KT = 1-min sustained winds of about 102KT.

Has there ever been a system of this strength, for this early for the south Pacific.

There was one much stronger.

Cyclone Bebe formed in late October 1972 as a "twin" to Typhoon Olga. Bebe was estimated to be a Category 5.

Bebe caused lots of damage and loss of life. Some of the islands battered by Cyclone Bebe were Fiji, Tuvalu, and Kiribati.

It has to be some large hurricane to be 105 mph, 935 mb. 935 mb would be a Category 4 or small Category 5 hurricane. Hurricane Katrina had 125 mph, 920 mb. Then again, if I remember, Wilma had 155 mph, 892 mb???????????

[AussieMark]

remember the sea pressure in pacific is lower than the ATlantic tho.

North America is the only agency that use 1 min sustained winds

everywhere else uses the global standard 10 min sustained winds

REMARKS:
240300Z POSITION NEAR 13.3S 169.2E.
TROPICAL CYCLONE (TC) 01P (XAVIER), LOCATED APPROXIMATELY 375 NM
WEST OF NADI, FIJI, HAS TRACKED SOUTHEASTWARD AT 04 KNOTS OVER THE
PAST SIX HOURS. TC 01P HAS INTENSIFIED RAPIDLY OVER THE PAST 12 HOURS
DUE TO IMPROVED POLEWARD OUTFLOW ASSOCIATED WITH THE MIDLATITUDE TROUGH
SOUTH OF THE SYSTEM. MID-LEVEL RIDGING ON THE EASTERN PERIPHERY OF TC
01P IN CONJUNCTION WITH THE TROUGH CONTINUE TO STEER THE SYSTEM IN A
GENERALLY SOUTHEASTWARD DIRECTION. TC 01P IS EXPECTED TO TRACK SOUTHEAST-
WARD THROUGH TAU 24 BUT WILL TRACK SOUTHWARD AFTERWARDS AS IT ENCOUNTERS
INCREASING VERTICAL WIND SHEAR ASSOCIATED WITH MIDLATITUDE WESTERLIES AND
STEER WITH THE LOW TO MID-LEVEL RIDGE. TC 01P WILL WEAKEN RAPIDLY AFTER
TAU 24 DUE TO THE AFOREMENTIONED SHEAR. THE AVAILABLE DYNAMIC AIDS ARE
IN FAIR AGREEMENT WITH THIS SCENARIO. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 240000Z IS 33 FEET. NEXT WARNINGS AT 241500Z AND 250300Z.//

NNNN

JTWC/NRL says 115kt-927mbar (1-minute).

[Sanibel]

WPAC hot spot 2006.

[Ptarmigan]

remember the sea pressure in pacific is lower than the ATlantic tho.

North America is the only agency that use 1 min sustained winds

everywhere else uses the global standard 10 min sustained winds

I wonder why everyone uses 10 min. sustained winds and we only use 1 min. sustained winds. I wonder why the sea pressure is lower in the Pacific?

[Matt-hurricanewatcher]

10 minute winds don't sound that good. I find the 1 minute better because you can get a better and faster reading. I never understood why the rest of the world uses the 10 minute.

More reasoning into why I say that? Is that adding in many guest, can destroy the accuarcy of the wind measurement. How do you keep 10 minut wind measurements, from doing that.


Also the recon every line is for 1 minute, how would you get a good measurement of the strength of the storm, with 10 minute spacings? I mean small storms you would miss the wind core all together.

OK.

MAX SUSTAINED WINDS - 115 KT, GUSTS 140 KT

Now that's more like it. And just now the eye is filling in, lol. On a bright note, the cyclone is a bit more circular then before.

[Aslkahuna]

Pressures in the WPAC and SWPAC are lower for a given intensity because the storms form in a lower ambient pressure. Wind sensors record the winds at intervals less than either 1 or 10 minutes but when reporting the winds, one averages the recorded winds for the reporting period and then report the peak gusts. BTW, the definition of a gust is also different for the WMO and what we report.
