Record warmth continues on Qld coast
Bushfire threatens Wollongong NSW
A dry winter finishes across much of Australia
Top temperatures today were 6 to 10 above normal across central Australia and along the Qld east coast. BoM
For the sixth day in a row, daytime temperatures along the Queensland coast were well above normal for August. Low Isles Lighthouse, 60km north of Cairns, broke its previous record maximum August temperature of 30.5 yesterday with a reading of 33°. Today's top was 32. The warm weather spread south down the coast, with Gladstone reporting a record August high of 30.9 at the Bureau radar facility which has 40 years of record, while the Te Kowai Experimental Station near Mackay registered 33.9, 9.3 above normal. While the departures from normal do not seem large in comparison with other parts of Australia, tropical coastal areas normally experience little variation in day-to-day temperature, and variations of 8 or 9° from the norm are in record-breaking territory.

Warm, windy weather fanned a bushfire, apparently deliberately lit, in the escarpment behind Wollongong this afternoon and evening. About 45 fire fighters battled the blaze in difficult terrain behind Mount Kembla which dominates the skyline behind the city. The fire was brought under control Friday.

With today's 9am reading, rainfall observers around the country totalled up their winter rainfall and, in many areas, found it wanting. The map at left (click to open a larger map in a new window) shows below or well below average rainfall was recorded across almost all of Western Australia and in a band across the nation's centre as well as along most of the NSW and Victorian coasts. The darker red areas are where rainfall was decile 1, or in the lowest 10% of winter rainfall recordings over the past 100 years; light red areas are decile 2 or 3, or in the bottom 30% of readings. The Sydney metropolitan area was one of the pockets falling within the lowest 10%, with just 81.6mm recorded, 228.5mm below average, and making it the equal second driest winter in the past century along with the winter of 1905. In 1970, 78.7mm was recorded, while the driest winter on record was in 1895, when just 43.2mm fell.
