Aussie (& S-Hemisphere) Cyclone Action 2011-2012


Recommended Posts

You just don't pay attention in the NIO or the WPAC. This isn't out of the ordinary for them. I forget which storm it was earlier this year (or maybe even last year?), but SATCON had something analyzed as a Cat 5 in the WPAC, JMA had 135 kts (10-min), SAB had T7.0 and JTWC only analyzed it at 110 kts. I swear, YOU, an enthusiast, are better at identifying intensities of TCs from satellite images than their trained Dvorak specialists.

:wub:

Well, in this case, I feel like I could have brought value to the process. :D

Video from a work camp in Port Hedland around 5 am. You can't see much, but the conditions look pretty rough. Highest winds occurred in Port Hedland around 4 am, so this would have been a little after. I do wish the person holding the camera had stepped a little closer to that opening-- could have captured more.

Details, pls. Thx.

MJO shifting from the Timor Sea to the Coral Sea should intensify the monsoon trough on the eastern side. Models aren't excited about genesis yet, but are showing increased monsoon activity. Of course, last time I put out a 10 day forecast for something like this, it busted horribly.

Gracias. What about prospects in the Northern or Western territory waters in the nearer term? The BoM outlooks are suggesting some possible action.

There's a Kelvin wave moving through later this week, which could set something off in the Timor Sea, but the models aren't too enthused. The favored area should shift from west to east around Monday or so, so the window is small.

As the signal shifts from west to east, there is a shot for a Gulf storm Mon-Wed next week, I'd imagine

OK, cool. Thx.

In other news... The BoM has issued their preliminary Cyclone Heidi report, which simply reflects the operational data. They haven't yet done postanalysis on this one, and I believe that will affect the final verdict Re: landfall intensity:

http://www.bom.gov.a...c20120109.shtml

The landfall point was very close to Port Hedland-- one of the closest in a very long time. The town was very near the inner core, although I believe-- after reviewing the radar loop-- that the true inner core missed the town by a few kilometers. This was an exceedingly small cyclone-- the most micro of microcanes. (More on that later.)

Check this out.

Nitso is our local legend. It's a great site, that will give great insight as to what is going on in Oz.

Yeah, nitso is awesome-- as is the whole Oz Cyclone Chasers crew. Great guys, and I enjoy corresponding with them about cyclones. They have a nice forum as well.

P.S. You missed Heidi. It was a really cute little cyclone. :wub:

Mozambique Met (find your own way round)

The good news, as alluded to by the tropical nerds (I am well rounded, interested in all types of weather, even snow not IMBY (3 IMBY events in less than 8 years) if it is absolutely awesome like Boxing Day 2010), things are looking up for Australia.

IDW10800

Australian Government Bureau of Meteorology

Western Australia

Tropical Cyclone three-day outlook for the Western Region

Issued at 2:00pm WST on Saturday the 21st of January 2012

Valid until midnight WST Tuesday

Existing Cyclones in the Western region:

Nil.

Potential Cyclones:

There are no significant lows in the Western Region. The monsoon trough is

expected to become active and one or two significant lows are likely to develop

within the trough by Monday. The risk of a tropical cyclone in the region

increases during next week. At this time it is not possible to say whether

coastal communities will be directly affected.

By late next week the monsoon trough may be producing gale force northwesterly

winds over areas to the south of the Indonesian archipelago including Christmas

Island.

Likelihood of a tropical cyclone forming in the Western Region:

Sunday :Very Low

Monday :Low

Tuesday :Moderate

Issued at 2:00pm WST on Sunday the 22nd of January 2012

Valid until midnight WST Wednesday

Existing Cyclones in the Western region:

Nil.

Potential Cyclones:

A tropical low lies in the monsoon trough near 12.4S 117.6 E. Activity in the

monsoon trough is expected to increase during the week and the tropical low at

12.4S 117.6E or another low within the trough is likely to become significant by

mid week. The risk of a tropical cyclone in the region increases during the

week. At this time it is not possible to say whether coastal communities will be

directly affected, but there is an elevated risk.

By Tuesday next week the monsoon trough may be producing gale force

northwesterly winds over areas to the south of the Indonesian archipelago

including Christmas Island.

Likelihood of a tropical cyclone forming in the Western Region:

Monday :Low

Tuesday :Moderate

Wednesday :High

Sorry I've neglected this thread for a couple of days-- was a bit busy over the weekend! Thanks, boomer, for posting that link to the Mozambique weather site-- much appreciated.

Funso continues to kind of meander in the Mozambique Channel.

But I think the bigger news this week is going to be in Oz. The pattern is getting more fertile, and the BoM is indicating a high threat of a cyclone in the Western waters and moderate threat in the Northern waters. The Western outlook is unusually explicit-- actually naming the specific regions that seem to be at risk (Kimberley, Pilbara, and Gascoyne-- or essentially the entire N coast of Western Australia).

Should be an interesting week.

The Euro's pretty suggestive, showing 1) a small, intense cyclone coming ashore in the Northern Territory S of Darwin (98S) nd 2) a very large, loose cyclone fishing into the open ocean as it misses the Gascoyne just to the N (97S):

The Euro is definitely the westernmost of the guidance for both 97S and 98S. I obviously considered it for my forecast today, but my track is east of both of those solutions.

FWIW, my tracks for both of these look closest to the 0z UKMet. I brought 97S in near or south of Exmouth in 5-6 days and left 98S with a 50/50 chance of developing before moving inland on the Top End.

Interesting-- thanks, Adam.

Re: 98S's landfall area, you're thinking somewhere along the N coast, E of Darwin-- like in the Van Dieman Gulf, or further E?
