Western Australia has been lashed by heavy rain and damaging winds
overnight, with more wild weather on the way.
Many places saw their heaviest rain in almost a decade as a line of
rain and storms crossed the state's west overnight. Significant rain
was widespread, extending from the South West Land division north to
southern parts of the Pilbara.
Acton Park and Busselton in the southwest of the state both saw their
heaviest rain since 2005, recording 86mm and 57mm respectively to 9am
this morning. Aston Downs, also in the South West, picked up the
heaviest official figure. Their 101mm was the heaviest rain in at
least nine years. Learmonth in the southern Pilbara collected 34mm,
its heaviest May fall in eight years.
In Perth there were widespread 25-50mm totals, with even heavier falls
close to the coast. Perth city, Swanbourne and Jandakot all saw their
heaviest rain since 2011, as well as their heaviest May totals in
Winds were also damaging as the band moved through, gusting as strong
as 96km/h at Rottnest Island west of Perth.
A deep low pressure system and associated trough have been the cause
of the wild weather.
While conditions eased periodically this morning, winds and showers
are picking up again as the low approaches the southwestern coast this
afternoon. At 12:30pm winds had gusted as strong as 100km/h at Garden
Island west of Perth, while Perth Airport saw winds reach 70km/h at
midday. As the low nears the coast tonight, destructive winds up to
125km/h are possible, peaking during the early hours of Thursday
Winds are likely to ease later on Thursday morning, however a cold
front will approach later in the day. This will bring further showers
and an increase in winds, although winds should not exceed 80km/h away
from the exposed coasts.
There is likely to be a further 25-50mm of rain for southwestern parts
of the state, heaviest near the coast. By the time the systems clear,
many places are likely to be sitting above their May average, not even
halfway through the month.
Looking further ahead, showers should begin to ease from Friday as a
high pressure system approaches the state's south. Most places can
look forward to a generally dry weekend, with only the odd shower or
two remaining about the southwest coasts.
