P.K.

It is purely based on wind speed. The storm surge etc is only there for guidance. The pressure is also related to the size of the TC so you need to be careful there. The JMA is the official scale for the NW Pacific. This is better than the TSR page as it uses official data http://severe.worldweather.wmo.int/. The NE Pacific is covered by the NHC so they use the SS scale, although it was only designed for the North Atlantic. ------------------------------------------------ MARINE WEATHER BULLETIN FOR ISLANDS AREA EQUATOR TO 25S BETWEEN 160E AND 120W. ISSUED BY FIJI METEOROLOGICAL SERVICE EQUATOR to 25S between 160E and 120W issued by Fiji Meteorological Service Apr 220800 UTC. PARTS 2 AND 3 : SYNOPSIS AND FORECAST VALID UNTIL Apr 230600 UTC. DEPRESSION 17F [1002HPA] NEAR 24S 178W MOVING SOUTH 05 KNOTS. APART FROM GALE WARNING 023 EXPECT CLOCKWISE WINDS 25 TO 30 KNOTS WITHIN 180 MILES OF CENTRE IN THE SOUTHERN SEMICRICLE AND 20 TO 25 KNOTS WITHIN 100 MILES OF CENTRE IN THE NORTHERN SEMICIRCLE.

The SS scale is based purely on winds and not pressure. It was created for the North Atlantic and so should not be used elsewhere. All the other basins have their own scales anyway.

Where did you see that?

Elia has almost completely gone.

It would still be a STS I guess as the SS scale only applies to TCs.

The NHC have upgraded that possible October STS so also included for last year is STS 19 from the 4th to the 5th October. (I know it is not really the 2006 season but I didn't know where else to post it without starting a new thread)

Don't worry I do, lol.

It is a tiny bit more than that, the SST anomalies in the North Atlantic are 0.26C from last month. 2006 1 26.38 0.54 25.41 -0.06 27.51 0.00 2006 2 25.77 0.31 26.68 0.28 27.81 0.08 2006 3 25.71 0.26 27.39 0.49 28.18 0.07

Wilma dropped 98hPa in 24 hours, this has just dropped 80hPa in 33 hours.

The BoM will not be copying the JTWC. The BoM and JTWC use different wind measuring periods anyway.

The SS scale is only used by the NHC. This system is close to being a cat 5 now.

It was upgraded to TC Floyd at 2100 GMT on the 20th March.

The title of this thread is a bit misleading, TC Floyd has been around since the 20th March and is reaching the end of its life.

Highest windspeed I've seen from landfall was sustained at 108kts using the standard ten minute average.

Not looking good here with Larry forecast to reach cat 4 just off the coast of Cairns. Currently 70kts, 965hPa.

I guess it might be the image I posted to S2K. Can't find any others that look good candidates during the Wilma period.

Good question. The problem with looking back at old sat images is all the other systems that also formed in October! It must be a new system as the subtropical depression 22 report is already out.

Turns out it was actually October, the report will hopefully be out soon.

30 named storms would be rather a lot. By the way there is now a 28th named storm from last year, no dates given by I read somewhere it was in April.

Hmm, strange it lists them as tropical storms there. They aren't called that is this part of the world. Currently a cat 1 although it reached cat 2 earlier. Bureau of Meteorology

It was named earlier. Use the proper page for SW Indian Ocean storms. Meteo-France, La Reunion

It is a bit odd, it should be Carina. By the way this is system number 9 rather than number 12.

The New Zealand Met Service declared this ET yesterday. There is no W Pacific basin, but the SW and NW Pacific basins. The NW Pacific season is all year round as I said above. That Navy page is intended purely for the USA's military, the local RSMCs have better local knowledge so I would always use them.
