An infeed of tropical moisture moved over South Australia from the NW during this week producing significant rainfall in many areas.

In the far north of the state, Tieyon Station recorded 167 mm and Hamilton Station 105 mm to 9 am on the 21st, . At Tieyon, the rain was most intense for a two to three hour period between 1 and 4 am. Overall, the rain was welcomed by pastoralists, despite flooded creeks, collapsed dams and lots of washed away fences.  Tieyon actually ended up with 213mm for the month. Several places including Tarcoola and Coober Pedy received more rainfall out of the system than they received for the whole of 2002!
Rainfall totals over 100 mm were confined to isolated stations in the Northwest and Far North districts. Rainfall totals between 50 and 100 mm were reported from much of the remainder of the Northwest and Far North districts, while totals below 50 mm were mostly reported from the Northeast district.
