Forum:2011-12 Southern Hemisphere tropical cyclone season

Welcome (a bit early)
Well, it's still 2011, but it's the official start of this forum... Not that anyone would care about it for now. I just felt like making it. =) Ryan1000 02:55, July 1, 2011 (UTC)

Since the year has begun, why don't we make some pre- season forecasts? So, who's ready?

I'll go with:

SWIO: 

14 disturbances, 12 depressions, 9 storms, 6 tropical cyclones, and 4 intense cyclones.

'''Aus. Region: '''

15 tropical lows, 12 tropical cyclones, and 6 severe tropical cyclones.

S. Pac: 

18 disturbances, 17 depressions, 13 tropical cyclones, and 7 severe tropical cyclones.

I'll make a mid-season forecast in February, and a late-season forecast in April. Andrew444 02:56, July 10, 2011 (UTC)

SWIO betting Pools are open! SWIO Betting Pools. Cyclone10 17:51, August 28, 2011 (UTC)

There's also betting pools for the entire SHem... Ryan1000 19:53, October 18, 2011 (UTC)

92S.INVEST
Another one near 90S.-- Cy10 -- 01:01, January 30, 2012 (UTC)

Gone.-- Cy10 -- 20:21, February 4, 2012 (UTC)

13S.HILWA
TCFA.-- Cy10 -- 02:07, February 14, 2012 (UTC)

Tropical storm 13S
Now a tropical storm by JTWC, though it hasn't been named Hilwa yet. Probrably will be later today. Ryan1000 10:36, February 14, 2012 (UTC)

Tropical Depression 10
Now a TD. &mdash;12R.KIEWII 12:30, February 14, 2012 (UTC)

Well it is now getting less organized as we speak and it has attained peak intensity. Maybe the JTWC were wrong to take it up to C2? &mdash;12R.KIEWII 19:43, February 14, 2012 (UTC)

May intensify later I would not take it out so fast as it may intensify later.Allanjeffs 23:57, February 14, 2012 (UTC)

Some significant change in the forecast. Was meant to weaken into a disturbance and stay that for the whole existence, however, it is now expected to strengthen into a moderate tropical storm, then weaken back into a tropical depression, then strengthen back into a tropical storm with 40 kt. &mdash;12R.KIEWII 11:24, February 15, 2012 (UTC)

Tropical Disturbance 10
And La Reunion have returned to the previous forecast, and only peaked at 30 kt. &mdash;12R.KIEWII 02:09, February 16, 2012 (UTC)

Tropical Depression 10 (2nd time)
And we have a TD again, looks like this thing will be going on an intensity roller coaster. &mdash;12R.KIEWII 10:56, February 16, 2012 (UTC)

Tropical Disturbance 10 (2nd time)
Yes it is..-- Cy10 -- 02:07, February 19, 2012 (UTC)

At one point, TD 10 was forecast to be a hurricane, and now it doesn't look like we'll get anything at all, not at this rate, at least. Fixed the header BTW (it was suposed to be size 4). Ryan1000 05:10, February 19, 2012 (UTC)

Tropical Depression 10 (3rd time)
Now forecast to become a MTS. &mdash;12R.KIEWII 12:32, February 20, 2012 (UTC)

At least we reach the H letter with this system how many more letter could we have. we will seeAllanjeffs 21:48, February 20, 2012 (UTC)

Moderate Tropical Storm Hilwa
Now named. &mdash;12R.KIEWII 16:23, February 20, 2012 (UTC)


 * Finally.-- Cy10 -- 17:24, February 20, 2012 (UTC)
 * It won't do much, but it formed, at least. Ryan1000 18:00, February 20, 2012 (UTC)

AOI: Eastern area of AoR
RSMC saying this low will develop into a tropical depression (I'm sure a tropical storm). &mdash;12R.KIEWII 22:37, February 21, 2012 (UTC)

AOI: North of the Mascareignes islands
RSMC saying this low will develop into a tropical depression (I'm sure a tropical cyclone). Have a look here. &mdash;12R.KIEWII 22:37, February 21, 2012 (UTC)

If that is true we will have two tropical cyclones in this basin next week if that is true we will have Irina and Joni with us.Allanjeffs 00:09, February 22, 2012 (UTC)

Looks like this one has the potential to become Irina or even Joni. Which ever low develops into a named storm first. By the way, if we get to Joni, we'd probably slow a bit down in activity in March. This season will most likely get to the K or L storm, if more show up. 173.169.56.34 01:01, February 22, 2012 (UTC)

By the time it makes landfall, the system will just stay there because of the mountains. The GFS forecasting over 350 mm of rain to fall over central Madagascar. However, a few days later it begins to move into the Mozambique Channel and strengthens quite a bit. It'll then make landfall as a tropical cyclone on Mozambique. Of course this is subject to change. &mdash;12R.KIEWII 08:26, February 22, 2012 (UTC)


 * At worst, this storm could be a re-Hudah and cause signifigant destruction in both Madagascar and Mozambique, but there is also a chance it could not develop past category 1 or 2. It's very large though, so rainfall could be a problem for the folks in Madagascar and Mozambique from this storm. They're still reeling from Giovanna's destruction, but I don't think this storm (future Irina) will be as strong as Giovanna when it does impact Madagascar. Ryan1000 14:41, February 22, 2012 (UTC)

13S.NONAME
Near Indonesia.-- Cy10 -- 04:19, February 11, 2012 (UTC)

Moving toward SWIO basin and with a TCFA.-- Cy10 -- 01:58, February 14, 2012 (UTC)

Now 13S.-- Cy10 -- 13:14, February 14, 2012 (UTC)

Tropical Disturbance 10F
And another one...-- Cy10 -- 13:11, February 3, 2012 (UTC)

Its not a depression. RSMC Nadi's TDS' supersede the 3-day outlook. &mdash;12R.KIEWII 15:31, February 3, 2012 (UTC)

Yeah its a disturbance not a depression.Allanjeffs 21:03, February 3, 2012 (UTC)

Exactly Allan, as 10F's final advisory has just been issued. &mdash;12R.KIEWII 20:51, February 5, 2012 (UTC)

Tropical Depression 10F
Now its a depression. &mdash;12R.KIEWII 13:29, February 4, 2012 (UTC)

Although the advisory says 25 kts, the gale warning says 35 kts for 10F. This is exactly what happened with 04F too. So this means 04F should have been Cyril and 10F should be Daphne. (Not likely to happen anyways). &mdash;12R.KIEWII 12:08, February 5, 2012 (UTC)

And after they reach td status they start weakening right away. Allanjeffs 17:00, February 5, 2012 (UTC)


 * Gone.-- Cy10 -- 20:51, February 8, 2012 (UTC)

Tropical Disturbance 11F
New one here, most likely to be dumped in the bin soon. &mdash;12R.KIEWII 20:51, February 5, 2012 (UTC)

Like all of the past disturbances of this year. Allanjeffs 23:25, February 5, 2012 (UTC)

Tropical Depression 11F
Potential for this depression to become a tropical cyclone is low. &mdash;12R.KIEWII 01:48, February 6, 2012 (UTC)

96P.INVEST
Now 96P. &mdash;12R.KIEWII 02:45, February 6, 2012 (UTC)

Tropical Cyclone Cyril
And its the first homegrown tropical cyclone of the season. &mdash;12R.KIEWII 19:43, February 6, 2012 (UTC)

Finally a name storm in this Basin btw Cyril is a male name or female? Allanjeffs 20:39, February 6, 2012 (UTC)

Cyril is a male name Allan. Being the latest first storm in the SPac on record, at best, this basin will get to 3-4 storms in total from now on out, excluding Jasmine. Even so, Cyril is only expected to peak as a TS as of now, but based on the looks of this tiny little storm, I wouldn't be surprised if Cyril could explode up to cat 1 or 2 strength before dying out. Ryan1000 22:15, February 6, 2012 (UTC)

So we got Cyril after all. Still, I don't see much coming from him. Andrew444 Talk  Blog  Contributions  23:19, February 6, 2012 (UTC)

It's heading out to sea. Cyril is probably a fish.-- Cy10 -- 23:20, February 6, 2012 (UTC)

Probable will only peak as a weak moderate tropical storm.Allanjeffs 23:56, February 6, 2012 (UTC)

It has reached C2 strengh. Now it should be weakening.-- Cy10 -- 13:17, February 7, 2012 (UTC)

Down to a C1 and has moved into TCWC Wellington's AoR. &mdash;12R.KIEWII 19:08, February 7, 2012 (UTC)

Ex-TC Cyril
Extratropicale &mdash;12R.KIEWII 19:37, February 8, 2012 (UTC)

Down and out.Allanjeffs 20:36, February 8, 2012 (UTC)

Tropical Depression 13F
And who thinks this will become Daphne? &mdash;12R.KIEWII 12:34, February 14, 2012 (UTC)

Maybe. Depends on how conditions will turn out. 173.169.56.34 21:55, February 14, 2012 (UTC)

I don`t think so.Allanjeffs 21:43, February 15, 2012 (UTC)

It's not gonna develop, it's being sheared up now. BTW, the Hall of Fame elections are taking place. If you want to vote on your picks from Eric's list of 2012's hall of famers, or make new suggestions for 2012, go there. Ryan1000 23:44, February 15, 2012 (UTC)

Remnants of 13F
Gone.-- Cy10 -- 17:59, February 18, 2012 (UTC)

INVEST
Not sure where to put this, but it is in the south Pacific atm, off the coast of South America. 1011 mbar. &mdash;12R.KIEWII 11:57, February 16, 2012 (UTC)

There never has been a storm recorded in the South Pacific east of 180 degrees west longitude before, and if this one, or if any one, does form in the future, it is unclear how it will be handled. We might as well leave it like this for now. Most of the coast of South America looks clear to me, but I do see one area of disturbed weather that is taking on some tropical charicteristics southwest of Ecuador. No storm has ever been recorded there before. This is a bit bizzare. Ryan1000 23:15, February 16, 2012 (UTC)


 * Well the disturbance is located near 10S, and the NHC monitors east of 120W and from 0 degrees to 18.5S. &mdash;12R.KIEWII 23:46, February 16, 2012 (UTC)
 * They can monitor it, but my main point was, this still isn't an actual tropical cyclone basin here, like the South Atlantic and Mediterannean. I would be rather baffled if this invest becomes a TS, but if that happens, it will probrably be left as an unnamed storm. It could develop, but I won't count on it now. It lost itself a bit on the latest pic, but it's not gone yet. Ryan1000 00:48, February 17, 2012 (UTC)
 * I don`t really think it will form ,but if a miracle occurs and form it will be unnamed I think.Allanjeffs 01:01, February 17, 2012 (UTC)


 * How unusual! I didn't think we'd be talking about a Southeastern Pacific invest! Andrew444  Talk  Blog  Contributions  01:36, February 21, 2012 (UTC)


 * You were a little late andrew.Allanjeffs 02:45, February 21, 2012 (UTC)
 * Yeah, its been gone for quite a while now. &mdash;12R.KIEWII 12:28, February 21, 2012 (UTC)

Retirements at a Glance
Here's mine:

AUS: SPAC: -- Cy10 -- 00:27, February 9, 2012 (UTC)
 * Fina - 0% - Just another name wasted.
 * Grant - 50% - If they retired Madga, why shouldn't this one?
 * Heidi - 10% - Flooding counts.
 * Iggy - <5% - Probably not.
 * Jasmine - <0.1% - Any damage in SPAC doesn't count.
 * Cyril - 0% - No.

Mine:

AUS: SPAC:
 * 1) Fina - 0% - No impact.
 * 2) Grant - 3% - Unlikely for retirement because although there were no deaths, there seriously was a train derailment?
 * 3) Heidi - 2% - Very unlikely for retirement because there were no deaths, and although there was some minor flooding going on, I didn't hear anyone saying this was bad.
 * 4) Iggy - 10% - No.
 * 5) Jasmine - 0% - Did nothing in the AUS area.


 * 1) Cyril - 0% - No impact.

 * Not any damage? You've missed a whole lot of stuff then. &mdash;13R.KIEWII 22:33, December 29, 2011 (UTC)
 * So Andrew, you call train derailment not part of the damage?-- Cyclone10 01:09, December 30, 2011 (UTC)
 * Well, I know Australia's track record is to retire everything that hits them (almost), but I still don't like being too generous. Not every tropical storm becomes retired in the region, but still, there is a descent chance for every one. Ryan1000 13:43, December 30, 2011 (UTC)
 * Cyclone10, a train derailment is part of the damage, just didn't hear about it. :( Andrew444  Talk  Blog  Contributions  22:56, December 30, 2011 (UTC)
 * Here's the link: .-- Cyclone10 02:31, December 31, 2011 (UTC)

Time for mine.


 * 1) Fina: 0% - Yes, a fail
 * 2) Grant: 20% - The first to cause damage in this season
 * 3) Heidi: 5% - Meh
 * 4) Iggy: 3%
 * 5) Jasmine: 15% - Caused record breaking flooding in NSW and QLD

&mdash;12R.KIEWII 21:34, January 21, 2012 (UTC)

My turn


 * 1 Fina......0% do I even need to tell you why ?


 * 2 Grant......8% just because Australia retire almost everything that cause deaths or damage but i really don`t think this one is going.
 * 3Heidi ......7%less than grant because i think that it cause less damge than him.
 * 4Iggy:25% kill 23 in Indonesia and cause damage he is the highest for retirement on my part I don`t give him more because I don`t know if Indonesia retire names.
 * 5 Jasmine:TBK
 * Allanjeffs 16:25, February 4, 2012 (UTC)

Might as well:

Australia: South Pacific:
 * Fina - 0% - Nope.
 * Grant - 23% - Australia has a common track record, but I still don't think Grant should be retired, especially in comparison to what they've seen in the past.
 * Heidi - 11% - Wasn't like Grant.
 * Iggy - 4% - Damage, if any, wasn't that bad for Australia.
 * Jasmine - 5% - Most of the damage was small, despite it's immense strength.
 * Cyril - 0% - Fishie.
