was observed in Norfolk Island during local night hours. Conditions 
at Darwin appeared to be degraded through local night hours, 
however analysis may have been impeded by an equipment issue.

are expected to be near predicted monthly values over 07-09 Jul, 
with mild depressions possible at local nighttime.
