Water in flooded rivers in the Centre began to recede today, but transport dislocation is expected for several more days on main highways and weeks on back roads. The Todd River in Alice Springs is expected to be below causeway level tomorrow, allowing repairs to begin. 17 stranded people were rescued from Hamilton Downs north of Alice Springs today, but a group of around 200 remain isolated at Erldunda Roadhouse on the Stuart Highway between the Alice and the SA border. Low cloud prevented the use of helicopters today, but food drops to isolated communities west of Alice Springs is due to begin with clearer weather forecast for tomorrow.
A freak, isolated rainfall event gave Tennant Creek Airport NT its highest April one-day rainfall on record. 105mm was recorded in the 24 hours to 9am, 68 falling yesterday between 9pm and midnight, and a further 32 to 6 this morning. The rainfall record at the Airport only goes back to 1969, but at the old post office site, which began recording rain from 1874, the highest one-day total for April has been 101.6mm. The unusual fall was not associated with the remains of TC Rosita. It occurred when moist northeasterlies converged into a trough lying east from a shallow low over the Victoria River District to western Queensland.
