Driving along the Pacific Hwy yesterday, significant tree damaged was observed from Halfway Creek (between Grafton and Coffs Harbour) all the way to Ballina (150km in distance). The major areas affected were Tyndale (south of Maclean), near the turnoff to Yamba at the Clarence River, then Woodburn, Wardell and into Ballina (other areas do not have many trees so it is hard to tell what happened there). Given the size of the trees and the type of damage, I estimate winds would be in the order of 150km/h or more to produce the destruction. Although large gum trees can be pushed over in non-severe winds, the area had been quite dry, so the ground wetness would not have been a factor in making them easy to fell. Trees over 1m in diameter had been felled in exposed locations, while in generally forested areas some large tress were over but many more branches in the canopy were destroyed. Splitting and twisted (of large) branches as Paul Mossman observed were widespread especially from Woodburn into Ballina. Ballina itself copped the storm between 6 and 7pm. 80mm fell in one hour at my parents place - 30mm with the strong winds and 1cm hail then the rest following. Ballina Airport approx 4km to the north recorded 90mm. Photos were taken by my father which I will make available as soon as I can. Another person I know here has taken many pics including aftermath damage which will be available as well. My father described the rapid approach of the cell from the south as a vast system spreading around towards the SE and E and also around to the SW and W of central Ballina. In the centre was a barrel structure with gale force northerly winds sprearing into and swirling up the tower. He indicated the circular structure of the central part of the storm. Both the eastern and western parts, and the core came together over town, smashing in with horizontal winds and large hail nearby. The winds battered from all directions lifting roofing and leveling trees. Power was knocked out with lines down. Flash flooding soon resulted as incredible rainfall enveloped the area. A comment he made was the lack of awareness of people at the river: swimming and fishing with severe lightning hitting very close by including in the river. They were oblivious to the looming storm and would have had to made a rapid escape at some stage. It is surprising no-one was injured. Fortunately for my parents no damage occurred at their place, but west Ballina and east Ballina really copped it. This mornings 'northern star' newspaper has a number of damage photos and has the heading 'super storm', with comments from Andrew Treloar indicating it was a supercell. Radar images I saw on Friday afternoon (while still in Sydney) showed the intense echos of the storm heading NE then track almost northwards once it reached the Yamba area. I suspect this was the time it beacame supercellular and started to more left of the 'normal' environmental flow that day. It covered the distance from Yamba to Ballina (80 km) in approx 1 hour. As this area is the most eastern in Australia, it was then out to sea once it passed through Lennox Head (12km north of Ballina) and clipped Cape Byron. Major damage also occurred at Murwillumbah (80km north) but this was from another cell a bit later on. ---oooOOOooo--- Lake Cattai (10km south of Port Macqaurie) copped a hailstorm earlier in the day. At my sisters place hail to 3.5cm (which she kindly saved for me to photograph!) occurred at 2.45pm. The hail missed Port Macquarie. regards, Michael in Ballina for two weeks *==========================================================* Michael Bath Oakhurst, Sydney mbath at ozemail.com.au Australian Severe Weather http://australiansevereweather.simplenet.com/ *==========================================================* -------------------------------------------------------------------------------------- 004 X-Sender: bayns at nornet.nor.com.au X-Mailer: Windows Eudora Light Version 3.0.1 (32) Date: Mon, 21 Dec 1998 15:47:18 +1000 To: aussie-weather at world.std.com From: steve baynham [bayns at nor.com.au] Subject: aussie-weather: gympie Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com coool, heaps of lightning off gympie at the moment according to the lightning tracker. its been overcast here today after a very hot morning. was sweating by 10 o'clock just driving in the car. had a very heavy rainfall about hlaf hour ago. some dark clouds looming:) just rain i suspect. steve from gold coast -------------------------------------------------------------------------------------- 005 From: "Jimmy Deguara" [jimmyd at ozemail.com.au] To: [aussie-weather at world.std.com] Subject: aussie-weather: Satellite imagery Date: Mon, 21 Dec 1998 18:10:28 +1100 X-Msmail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.5 X-Mimeole: Produced By Microsoft MimeOLE V4.72.3110.3 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Due to the following repsonse from the maintainer of the high resolution imagery site, I must please ask everyone not to send any comments as to whether it is working or not. I did just that in order to get it going again and this was the response ....."The page is generated through automatic processes, see text. If it aint working, it just aint. Please keep in mind that this service is costing us in CPU and other resources and SHOULD BE costing you upwards of $120 PER WEEK ? I do what I can when I can to keep it up but I give you no and have no commitment to maintaining the site and warn that it may be shut down at anytime without warning."..... As we don'y want to lose this great resource, I would suggest leave any comments to myself or Michael Bath and we will communicate it to the maintainer.
