ex-TC Steve tracked across the northern Kimberley district of WA overnight and today bringing heavy rain and squally winds across the region. Derby's Curtin Airfield recorded 217mm between 9am yesterday and 3 this afternoon, and other significant falls are shown at left. Steve moved offshore again near Broome, and deepened once more to tropical cyclone strength mid afternoon as it tracked westwards, parallel to the coast.

Severe thunderstorms developed over the NSW Central Tablelands today in moist air converging into an inland trough. 2cm diameter hail was reported from Lithgow around 2pm from a storm complex that moved east, giving Katoomba a series of downpours during the mid afternoon as successive storm cells passed overhead. The Katoomba observer reported 91.4mm for the 48 hours to 9am Monday, but most fell during these storms, producing the unusual event of local flooding on the Blue Mountains ridge top. The storms diminished in intensity as they moved east and northeast into Sydney and the lower Hunter Valley, but still gave widespread falls of 20 to 30mm. This event is explored in detail by Matt Smith.
