Record August heat on Queensland's tropical north coast
Strong winds, heavy showers in SW WA
Light winds and exceptionally low humidity allowed daytime temperatures to soar along Queensland's north tropical coast today, producing record August maximum temperatures at at least two locations (see box below). Cairns Airport's midday relative humidity was only 27%, while inland at Hughenden, the 3pm humidity of 10% was accompanied by a temperature of 35, 7 above normal.

A strong pressure gradient developed ahead of a cold front as it approached Western Australia's southwest this evening, bringing heavy showers to the Darling Range behind Perth and gale to storm force winds around the coast. Bickley, southeast of Perth CBD and at the foot of the range, recorded 49mm for the 24 hours to 9am Thursday, mostly falling during the evening and overnight. Other high 24 hour falls are shown in the rainfall box for 31 August. Gales began at Cape Leeuwin mid afternoon, with a peak sustained wind speed of 93km/h recorded at 4.49pm.
