Tropical Cyclone Yasi, which hit Queensland last week moved southwest into the interior as a tropical low late on Friday the 4th. Yasi brought a large amount of moisture and unstable air into the Northern Territory on Saturday, causing widespread heavy rain and storms. The Barkly and Alice Springs were drenched especially. 115mm was recorded in Tennant Creek during the 72 hours from Saturday 5th to Monday 7th, while 140mm fell at Alice Springs in the same period. While the Northern Territory was soaked a broad trough filtered moisture into the southeast, allowing widespread storms and heavy rain to develop. Much of Victoria and southern parts of New South Wales recorded three to four times their monthly average rainfall in only 24 hours. Yasi has weakened significantly in the last few hours but has still managed to bring heavy rain to parts of Western Australia overnight. Forrest Daily in the Eucla recorded 44mm to 9am, which is their wettest day in 11 years. The remnants of Yasi are almost gone but moist air is expected to linger around in eastern parts of Western Australia for the next 48 hours.
