For people in Lower West and parts of Central West, Great Southern and Central Wheat Belt districts.

Issued at 2:34 pm Thursday, 3 October 2019.

Severe weather conditions possible as a deep low moves across southwest WA during Friday.

A low pressure system is developing off the west coast. The low is expected to deepen and move across the coast during Friday afternoon and evening.

The system is likely to cause extended periods of DAMAGING WINDS averaging 60 to 70 kilometres per hour with gusts to 100 kilometres per hour which could cause DAMAGE TO HOMES AND PROPERTY. The potential for DAMAGING WINDS along coastal parts between Mandurah and Dongara commences during Friday morning from about 8:00am and then extends inland during the day.

DAMAGING SURF CONDITIONS are likely which could cause SIGNIFICANT BEACH EROSION.

Tides will be higher than expected.

This weather is unusual for this time of the year; this low is likely to be windier than a typical winter system and may cause damage to property and make road conditions hazardous.

The worst conditions are likely in coastal parts of the warning area.

Locations which may be affected include Mandurah, Moora, Northam, Perth, Jurien Bay, Lancelin, Pingelly, Wongan Hills and Yanchep.
