Some of the heaviest rain in years fell in Tasmania's drought-stricken southeast today as the low pressure system that brought torrential rain to Bass Straight Islands yesterday moved down the state's east coast. Virtually the whole eastern and southeastern coasts recorded between 50 and 100mm over the 72 hours to 9am Saturday. Twilight Valley, between Copping and Nugent, recorded 85.8mm for the 48 hours to 9 this morning, while the summit of Mt Wellington registered 103mm in the 24 hours to 9am Saturday in the moist easterly winds, most of it falling today.

The area has suffered record or near record rainfall deficiencies over the past 3 years, and, although winter rainfall has been average, rain for the past year has been 20 to 40% below average, or in the bottom 10% of annual rainfall.

Mt Isa Queensland had its coldest August morning on record, when the mercury dropped to -1 at the airport. The reading followed a minimum of zero yesterday morning. Georgetown, to the east, recorded a minimum of 2. Both are between 11 and 12 below average for August. Meanwhile, Bidyadanga, near Broome in Western Australia recorded its hottest August day on record with a maximum of 38.0.
