2. FORECAST (31 AUGUST - 02 SEPTEMBER)
Date   T index  Conditions       MUFs                              
31 Aug    90    Normal           Near predicted monthly values
01 Sep    70    Normal           Near predicted monthly values    
02 Sep    80    Normal           Near predicted monthly values   

COMMENT: MUFs have been around predicted monthly values across 
Australia, with variable conditions in equatorial regions. Mostly 
normal to enhanced conditions are expected for day 1, with some 
chance of depressed periods at local nighttime, particularly 
in southern Australia. Some mildly depressed periods may be expected 
for day 2, again more likely and more severe in southern regions. 
Conditions for day 3 should be around predicted monthly values. 
This variability described is expected due to anticipated geomagnetic 
activity following the arrival of a coronal hole high speed solar 
wind stream.
