Australian region. 

There may be intervals of strongly enhanced conditions at equatorial and
tropical locations. 

Local depressions may occur during 13 Mar if the predicted CME impacts Earth.

SWFs are probable early in week.

T index: 110

IPS SWF HF Communications Warning 6 was issued on 9 March and
