Tropical Cyclone Yasi
 

Afternoon all,
Have been watching the cyclones of late very closely, hoping that I won't end up back in Brisy because of more flooding in Rockhampton, but after monitoring Cyclone Yasi over the last day or so, my wish isn't looking that great if it hits anywhere near the Rocky area, :(.

Handy link, showing an animated satellite image of the South West Pacific region, TC Yasi quite visible. http://www.goes.noaa.gov/sohemi/sohe...hirgmscol.html

The shear size of it is absolutely amazing. It'd be interesting to know how large the area actually is that contains gail force and destructive winds, but going on what other cyclones are normally like, the gail force winds area normally is the same size as the visible cyclone itself!

One to certainly keep an eye on if you're a keen weather watcher.

Mick,

I agree that is a real monster.

Hope it chills out a bit (a lot) before it hits any part of the east coast.

With still some water to cover yet before it hits, makes that a tough ask!

My fingers are crossed for all in Qld, I think you have had more than enough for one or more years.

Kind regards,

Geoff

Great link Mick. That's far better than some of the track maps the Aussie BOM website displays. Really does show the sheer size of the monster!

However, this is the BOM's current plot for Severe TC Yasi: http://www.bom.gov.au/products/IDQ65002.shtml
The track plot has coloured regions indicating gale force, destructive, and very destructive wings.

Currently it's a Cat 3, but it's expected to intensify to a Cat 4 very close of the Townsville-Ayr coast. Definitely one to keep an eye on.

Cheers

I have family in Ingham, which is right where the epicentre is expected to be. It's a bit hectic up there at the moment.

Gee Andrew I SO wish I could disagree with you, but I cant.

All the best to your family and all other board members and the whole community/ies of FNQ.

Take lots of care at this time.

Kind regards,

Geoff

Briefing for Cairns:

wouldn't want to be there at 9pm tomorrow!

At least it's straight down the runway, however it may be a very slow final.

...particularly in a C172!

That's 259.28km/h :eek:

I'll assume this to be outside the crosswind limits for most aircraft!

There are plenty of movements to/from Far North QLD this evening moving both people and aircraft to safer locations.

Yep most aircraft including commercial jets have a x-wind limit of 30-40 kts. However some aircraft only list a demonstrated x-wind, which means on the day they did the test they did not get to test the full limit as there was not enough x-wind.

With that wind landing on RWY 15 in CS if your were stupid to give it a go would only give you a few Knots of x-wind, but even if the aircraft I fly which has Vref speeds for landing of 120 -140 knots final would be rather slow and not very nice:eek:
