Severe Weather Warning
for damaging winds and heavy rainfall
for people in the Central West, Lower West, Great Southern and Central Wheat Belt forecast districts

Issued at 4:05 pm WST on Thursday 30 July 2015.

For people in parts of WA west of a line from Geraldton to Morawa to Southern Cross to Hyden to Mandurah. This includes people in, near or between the following towns: Geraldton, Jurien Bay, Dalwallinu, York, Southern Cross, the Perth Metropolitan area and Mandurah.

Weather Situation

A rain band with embedded thunderstorms currently lies across northern parts of the warning area. At 3:30 pm, satellite and radar imagery showed areas of moderate to heavy rain between Geraldton and Lancelin, extending eastwards towards Southern Cross.

Areas of heavy rain will extend southwards during Thursday evening and will lie close to or over the Perth Metropolitan area. Heavy rainfall is more likely over areas to the north of Perth but there remains a risk that Perth will receive rainfall heavy enough to cause FLASH FLOODING. The period of greatest risk for the Perth Metropolitan area is from about 8pm Thursday through to about 2am Friday morning.

The rain band is expected to produce HEAVY RAINFALL that may cause FLASH FLOODING through parts of the warning area. The rain will ease during Friday morning and contract eastwards.

Flood Watches have been issued for the Central West, Central Wheat Belt and Lower West Districts. For further details please refer to http://www.bom.gov.au/wa/warnings/.

There is also the slight risk that thunderstorms with DAMAGING WINDS in excess of 90 kilometres per hour could cause DAMAGE TO HOMES AND PROPERTY during late Thursday afternoon and evening northwest of a line from Lancelin to Wongan Hills to Morawa to Geraldton. This risk of DAMAGING WINDS will ease during Thursday evening. Damaging winds are not expected in the Perth Metropolitan area.

Between 9am and 3:00pm Thursday, the following rainfall totals have been recorded:

Watheroo (DAFWA): 24.8 millimetres.

Three Springs (DAFWA): 24.2 millimetres.

Warradarge East (DAFWA): 20.8 millimetres.

This weather pattern is not typical for this time of the year and winds and particularly the rain may cause damage to property and make road conditions hazardous.

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 there is flooding, create your own sandbags by using pillow cases filled with sand and place them around doorways to protect your home.
  • If boating, swimming or surfing leave the water.
  • Do not drive into water of unknown depth and current.
  • Slow down and turn your headlights on.
  • Be alert and watch for hazards on the road such as fallen power lines and loose debris.
  • If it is raining heavily and you can not see, pull over and park with your hazard lights on until the rain clears.

If your home or property has significant damage, like a badly damaged roof or flooding, call the SES on 132 500.

The next warning will be issued by 7:00 pm WST Thursday.
