2. FORECAST (24 MAY - 26 MAY)
Date   T index  Conditions       MUFs                              
24 May    75    Normal-fair      Near predicted monthly values

COMMENT: HF conditions were normal at N.Aus/near-equatorial regions, 
slightly degraded in S.Aus/NZ and poor in the Antarctic regions 
over the UT day. MUFs remained mostly near predicted monthly 
values in Aus/NZ/near-equatorial regions, with just some isolated 
depressions overnight in N.Aus. The Antarctic regions saw degraded 
HF conditions and depressed MUFs as a result of localised activity. 
MUFs are expected to be mostly near predicted monthly values 
for the next three days, although some ongoing MUF depressions 
are likely in S.Aus/NZ/Antarctic regions day 1 (24 May). Minor 
degradation of HF conditions may also be experienced in these 
regions.
