Issued at 10:59 am Saturday, 23 May 2020.
Widespread severe weather likely over western parts of WA with
dangerous weather in some parts.
Weather Situation:
A tropical system will combine with a cold front to produce a
vigorous trough extending the length of the west coast. A deep low
pressure system is expected to pass near the South West of the
state Sunday night, while it is possible other lows may form along
the trough as it impacts western parts of WA. Widespread severe
weather is expected from Sunday morning. Dangerous weather may
occur in some parts, particularly in the vicinity of the
lows.
WIDESPREAD DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts
to around 100 km/h are likely and could cause DAMAGE TO HOMES AND
PROPERTY. DAMAGING WINDS are forecast to develop in coastal areas
between Onslow and Kalbarri, including Exmouth, Carnarvon and
Denham, from early Sunday morning. DAMAGING WINDS will extend to
southwest of a line from Onslow to Meekatharra to Kalgoorlie to
Esperance, including Geraldton, the Perth Metropolitan area,
Mandurah, Bunbury, Busselton and Albany during Sunday afternoon and
evening.
Locally DANGEROUS WINDS, averaging 80 to 90 km/h with peak gusts
of around 130 km/h are possible near the low pressure systems
during Sunday afternoon and overnight. DANGEROUS WINDS could cause
SIGNIFICANT DAMAGE OR DESTRUCTION TO HOMES AND PROPERTY.
Winds are expected to ease across the Pilbara and Gascoyne
overnight Sunday night and through the South West Land Division
during Monday.
HEAVY RAINFALL that may lead to FLASH FLOODING is possible
northwest of a line from Kalbarri to Onslow during Sunday with
isolated rainfall totals to around 100mm. HEAVY RAINFALL may also
occur southwest of a line from Kalbarri to Albany from Sunday
afternoon with isolated rainfall totals to around 70mm.
Residents in coastal areas between Exmouth and Augusta are
specifically warned of the POTENTIAL OF A DANGEROUS STORM TIDE.
Tides are likely to rise SIGNIFICANTLY ABOVE THE NORMAL HIGH TIDE
MARK with DAMAGING WAVES and DANGEROUS FLOODING.
DAMAGING SURF CONDITIONS are likely which could cause SIGNIFICANT
BEACH EROSION.

Busselton, Carnarvon, Esperance, Exmouth, Geraldton, Kalbarri,

Meekatharra, Merredin, Moora, Mount Barker, Mount Magnet, Narrogin,

This is a rare event for WA particularly due to the extent of the
area affected and the possibility of multiple areas of dangerous
weather.
The Department of Fire and Emergency Services advises that people
should:
* If outside find safe shelter away from trees, power lines, storm
water drains and streams.
* Close your curtains and blinds, and stay inside away from
windows.
* Unplug electrical appliances and do not use land line telephones
if there is lightning.
* If boating, swimming or surfing leave the water.
* Be alert and watch for hazards on the road such as fallen power
lines and loose debris.
* Keep away from flooded drains, rivers, streams and
waterways.
* Be careful of fallen trees, damaged buildings and debris.
* Be careful of fallen power lines. They are dangerous and should
always be treated as live.
* Assess your home, car and property for damage.
* If damage has occurred take photos and contact your insurance
company to organise permanent repairs.
* If your home or property has significant damage, like a badly
damaged roof or flooding, call the SES on 132 500.
