 WA: Isolated heavy
rain continues
Following the heavy rain events of the past week or so in SW WA, isolated
heavy falls are continuing to be experienced near the trough/low system shown
on
the analysis
charts above. Yesterday, Kellerberrin in the Central Wheatbelt recorded
30mm between 9am and 3pm, while heavy short-duration gaugings today were widely
scattered and included 7.2mm in 9 minutes at Jandakot Airport in Perth, 9.6mm
in 10 minutes at Morawa in the Central West and 27.2mm in 30 minutes at Barrow
Island and 28.2 in an hour at Onslow Airport, both in the West Pilbara. The
highest 24 hour reading to 9am today was 64.0mm at Cardabia, 135km SSW of Exmouth.
Heavy 24-hour totals to 9am Sunday, most of which fell today, included 56.0mm
at Barrow Island and 48.0 at Colorado in the Central Wheatbelt, 60km NE of
Narrogin.
AUS:
Minimum temperature extremes across the nation
Minimum temperatures showed an unusually broad range across the nation this
morning. In the southern half of WA, where a huge cloudmass trapped warmth
from prevailing northerlies, minima were up to 9C above normal. An exceptionally
large area of the east and north of the country, however, experienced overnight
lows 4 to 9 below normal, with the greatest departures unusually
in the tropics, not known for great temperature variability. In northern QLD,
Mt Isa Airport's low of 4.8 was 9.2 below average and Georgetown's 8.1 was
8.0 below, while just across the border in the NT, and just 60km from the Gulf
of Carpentaria, Wollogorang recorded a low of 7.4, 8.1 below normal. On Cape
York Peninsula halfway between Cairns and Weipa, Musgrave Station recorded
a low of 11.6, just 0.1 shy of its record May low. A broad flow of cool,
dry southern air up the eastern side of the prominent high
pressure
system shown on the analysis chart above is responsible for the unusually widespread
low minima. |
