Yellow Warning for the ACT

The ACT Emergency Services Authority has issued a Yellow Warning (likely impact) for the ACT following the release of a severe storm warning by the Bureau of Meteorology. I can’t find the ESA announcement online (which is odd for them lately), so here is the Bureau’s announcement.

NSW/ACT SEVERE THUNDERSTORM WARNING
for LARGE HAILSTONES, DAMAGING WIND, VERY HEAVY RAINFALL and FLASH FLOODING
For people in the
Central West Slopes,
Central Tablelands,
South West Slopes,
Southern Tablelands,
the ACT and parts of the
Northwest Slopes,
South Coast,
Northern Tablelands,
Mid North Coast and
Hunter Forecast Districts.

Issued at 2:35 PM Saturday, 10 February 2007.

Severe thunderstorms are likely to produce damaging winds, very heavy rainfall and flash flooding and large hailstones in the warning area over the next several hours.

Major locations within the warning area include Orange, Mudgee, Bathurst, Katoomba, Canberra, Goulburn, Cooma, Yass, Young, Tumbarumba, Armidale and Glen Innes.
Large hailstones are most likely in the southern part of the warning area.
The State Emergency Service advises that people should:
* Move your car under cover or away from trees.
* Secure or put away loose items around your house, yard and balcony.
* Keep clear of fallen power lines.
* Keep clear of creeks and storm drains.
* Don’t walk, ride your bike or drive through flood water.
* Unplug computers and appliances.
* Avoid using the phone during the storm.

* For emergency help in floods and storms, ring your local SES Unit on 13 2500.
* In the ACT, ring the ACT Emergency Service on 6207 8455

The next warning is due to be issued by 5:35 PM.

This warning is also available through TV and Radio broadcasts, the Bureau’s website at www.bom.gov.au or call 1300 659 218. The Bureau and State Emergency Service would appreciate this warning being broadcast regularly.

Update 3:10pm: And here’s the press release from the Emergency Services Authority

A YELLOW LEVEL warning for a possible storm threat to the ACT has been issued as part of the ACT All Hazards Warning System following the issuing of a severe thunderstorm warning by the Bureau of Meteorology.

The Bureau advises the storm may produce large hailstones, damaging winds, very heavy rainfall and flash flooding over the next several hours.

The YELLOW LEVEL warning covers the period from 1400 Saturday 10th February 2007 to 1800 Saturday 10th February 2007.

”The ACT SES has placed units on standby as a precaution at this stage and are ready to respond if required by the community,” ACT State Emergency Service Deputy Chief Officer Bren Burkevics said.

“Residents should refer to Emergencies and the National Capital – A residents guide available on www.esa.act.gov.au ,”he said.

“The ACT State Emergency Service advises that as storms approach, residents should:
Put vehicles under cover or cover them with blankets
Secure or put away loose items around your home, yard and balcony

Keep children and animals away from storm water drains

“During and after the storm, residents should:
Take extreme care when driving

Avoid using the telephone during the storm

FOR ACT SES EMERGENCY HELP IN FLOODS AND STORMS CALL 132 500
FOR LIFE THREATENING EMERGENCIES CALL 000

Also, I would just like to congratulate 2CC who broadcast the warning before the Bureau publicly released it, and broadcast it immediately, rather than waiting until the weather update.. The Bureau obviously told the ESA first, and they got the fax out first. Well done 2CC, this is a vast improvement over the New Years Eve fiasco, and even over previous regular practice.

Update 6:04pm: I was just about to give up all hope of rain, but out of the blue another storm cell is developing rapidly to the west of Canberra and is on its way in…hopefully this doesn’t dissipate like the last two did! This one appears to be part of a growing storm front so the chances of it dissipating are negligible.

Here’s the weather radar picture from 5:20pm, which pretty much sums up the afternoon’s rain pattern.

And here’s the one from 6pm showing the growing storm front to the west and north-west of Canberra. (I’m in a bit of a hurry, I’ll resize the images shortly).

I better take Nattie for her walk now before the rain hits! End Update

Update 7:15pm: Looks like people south of Lake Burley Griffin are copping a battering. We’ve had fairly tame rain in Reid, but there was a lightning strike within a couple hundred metres of my house not long ago (Nattie was not impressed).

In related news, ABC TV News has reported that western New South Wales from Dubbo, up to Cobar and out to Bourke, is without power after the storm caused a fault on a main transmission line. Power has been restored to Dubbo Hospital, but the lines are only able to support a very small amount of power at the moment. Electricity transmission authority TransGrid have three crews out trying to find the fault on the 180km long cable, but are having trouble due to the storm, and have no idea when power will be restored.

The devil you know

Good afternoon Glenn,

Just listening to your comments about attraction to "bad boys" being a case of "better the devil you know than the one you don't". Well that reminded me of my thoughts on the New South Wales election which, in my view, looks like it could be a battle between the devil you know, and the devil who couldn't possibly do any worse.

Not an attractive choice!

Morning John

Good morning John,

I was looking at a map yesterday and noticed a town named "Robertson" about 20km north-west of Kiama, and by the looks of it, within the 2UE reception range. Do you think Clive knows there is a town named after him?

I suppose you remember that last weekend I told you about a strange dream I had about scientists arguing over which celery to use to stop global warming…well I had a couple other strange dreams not long after that, one involving a coal mine and a grizzly bear in south-western Canberra, and another involving an argument about the time on a clock at the ACT Legislative Assembly, them deciding that they like their clocks to be wrong, and then wanting to name one after me for complaining about it!

By the way, thank you to your friend Harold in the UK who sent me a joke by email…I'll send a copy to you John (assuming Harold hasn't already done so).

Regards,
Samuel Gordon-Stewart
