Issued at 11:07 am Monday, 26 July 2021.

A strong cold front will move across the South West Land Division Monday afternoon and evening which will bring strong winds and heavy rainfall.

Weather Situation: An intensifying cold front will reach the South West District during Monday afternoon. Ahead of the cold front a developing rain band will bring heavy rain and possible strong squalls to western parts of the South West Land Division from late afternoon Monday. This weather will extend eastwards overnight Monday and continue into Tuesday.

WIDESPREAD DAMAGING WINDS, averaging 60-70 km/h with gusts to 120 km/h are likely to develop southwest of Bunbury to Bremer Bay from early afternoon, extending to be southwest of Jurien Bay to Bremer Bay, including the Perth Metro area from mid to late afternoon. DAMAGING WINDS will extend northward and eastward to the remaining warning area overnight Monday and into Tuesday morning.

Locally DANGEROUS WINDS with gusts in excess of 125 km/h are possible southwest of a line from Geraldton to Bremer Bay and may develop from mid-afternoon and continue through the evening.

HEAVY RAINFALL which may lead to FLASH FLOODING may develop over the northern South West and Lower West districts, particularly near the Darling Scarp, from mid afternoon. Moderate to heavy falls may extend into the west of the Great Southern later Monday afternoon and evening.

A Flood Watch is current for some catchments in the southwest. See http://www.bom.gov.au/wa/warnings/ for more information.

Tides are expected to be HIGHER THAN NORMAL today between Shark Bay and Israelite Bay. HIGHER THAN NORMAL TIDES may cause FLOODING OF LOW LYING COASTAL AREAS with VERY ROUGH SEAS between Perth and Israelite Bay on Tuesday.

DAMAGING SURF CONDITIONS are likely which could cause SIGNIFICANT BEACH EROSION between Jurien Bay and Walpole Monday, extending to areas between Shark Bay and Israelite Bay on Tuesday and continue for the rest of the week.

This front is expected to be windier than a typical front and is likely to produce the kind of weather that is only seen around twice a year in the southwest of WA.

Locations which may be affected include Albany, Bunbury, Esperance, Geraldton, Katanning, Mandurah, Manjimup, Margaret River, Merredin, Moora, Mount Barker, Narrogin, Northam and Perth.

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.
