depressed throughout the Australian region during 1 Jul. The
conditions were more strongly depressed at low latitude stations
and recovering at mid-latitude locations. For example, the daily
T index for Darwin was 40 and for Brisbane 70. The conditions
are expected to be depressed at low latitude stations again today,
and mildly depressed at mid latitude locations. Hobart passed
