ANY OF THE MODS would you like to re name this thread to the reast of the southern HEM season as all the tc's atm seem to die out so quick

worth one thread atm

[Aussie Big Ben]

This shows that Glenda is predicted to make landfall in about 48 hours. according to the JTWC in 48 hours she will be a category 4, winds around 95 knots gusting to 115 knots.

http://data.theweather.com.au/access/image...s_wa_latest.jpg

Is this what I've seen referred to as a pinhole eye? What does that mean for a system?

This is a very quickly developing storm from nothing to cat 3 in under 24 hours, probably a cat 4 already, if so how much further will it develope?

Sorry couldn't post the image, the link is dynamic. I'll search for one that can be posted.

Edit yep here is one that works.

.

[Aussie Big Ben]

This has got to category 4 from its forming in about 36 hours, is it just me or is that really quick? predicted to strengthen further, is another cat 5 going to happen?

Severity Category : 4

[summer blizzard]

Could somebody tell me what the sustained windspeeds are please as i can only find the maximum gusts????????

Advisory 30 is not out yet.

SITUATION

At 0600UTC Severe Tropical Cyclone Glenda located within 20 nautical miles of

Latitude sixteen decimal zero degrees South [16.0S]

Longitude one hundred and twenty one decimal one degrees East [121.1E]

Recent movement : West southwest at 6 knots.

Maximum winds : 100 knots.

Central pressure : 925hPa.

100 knots converts to 115mph, by 06:00 tommorow, Tropical Cyclone Glenda is expected to have sustained winds of 138mph, i am not sure which scale the Australians use because by the Saffir-Simpson scale, Tropical Cyclone Glenda should currently be a category 3, increasing to category 4 tommorow.

[P.K.]

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

[Aussie Big Ben]

The eye is tiny. Idf you look at the broome 256k radar loop, you can clearly see the eye. Looks to be about 10km (6 miles) across.

http://mirror.bom.gov.au/products/IDR172.loop.shtml

My bad on number thirty, I saw 9pm and assumed AEDT, I was 3 hours out. 30 due in about 2 hours

[Joneseye]

Is this what I've seen referred to as a pinhole eye? What does that mean for a system?

I remember Rita had a pinhole eye, which as far as I can tell makes it very dangerous as it can lead to rapid drops in central pressure.

For clarification somebody like Kold Weather or Mondy may be able to help?

Ian

[Aussie Big Ben]

Summer blizzard, from the BOM website.

So it's currently 115kts gusting to 140kts (from JTWC) - 115kts is about 210 (115*1.85) which makes it a category 5. the BOM update will reflect this I suspect.

[kold weather]

Yes it does look like a pinhole eye to me, very small indeed though there have been smaller but I'll get to that later.

They are usually a sign of rapid strengthening with a tight pressure gradiant causing very high winds indeed.

Usually though even the powerful systems can't hang onto the pinhole eye for more then 12-18hrs before undertaking a eyewall replacement, and it'll be this that will weaken Glenda I suspect tommrow IF it follows the norm.

Anyway the smallest eye ever recorded must surely fall to one of the most powerful hurricanes ever:

WILMA:

[P.K.]

So it's currently 115kts gusting to 140kts (from JTWC) - 115kts is about 210 (115*1.85) which makes it a category 5. the BOM update will reflect this I suspect.

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

[wolves78]

the eye looks better on this sat image looking like its getting stronger cat 5 soon

Nah, I'm in Melbourne recovering from the Commonwealth Games.

88MB in 36 hours is a fair drop in pressure. I wonder if Glenda can get below 900?

2!/2 hours for cat 2 to 5, that's scary.

This was from earlier on today - the eye just forming.
