DAMAGING, POSSIBLY LOCALLY DESTRUCTIVE WINDS AND HEAVY RAINFALL EXPECTED WITH A COLD FRONT OVER THE SOUTHWEST FROM SUNDAY MORNING. A SECOND SEVERE FRONT IS ALSO EXPECTED ON MONDAY.

Weather Situation: A strong cold front will approach the southwest of the state on Sunday, bringing vigorous northwesterly winds and a stream of tropical moisture over western parts of the South West Land Division. The front is expected to reach the far southwest from the late morning and extend along the west coast, reaching Perth during the afternoon. Conditions will briefly improve overnight on Sunday before a second cold front approaches on Monday morning, bringing widespread impacts to broader parts of the South West Land Division for the remainder of the day.

Strong northwesterly DAMAGING WINDS averaging 50 to 65 km/h with peak gusts of around 100 km/h are likely to develop about the front over the South West district during Sunday morning, extending to the Lower West and South Coastal districts, including Perth, during the afternoon. Locally DESTRUCTIVE WIND GUSTS with peak gusts in excess of 125 km/h are also possible along the front over coastal parts of the South West and Lower West districts south of and including Mandurah during Sunday afternoon and may cause SIGNIFICANT DAMAGE TO HOMES AND PROPERTY.

HEAVY RAINFALL which may lead to FLASH FLOODING is also possible with showers and thunderstorms about the front for parts of the South West, Lower West and South Coastal districts, including Perth, during the late morning and afternoon. Six-hourly rainfall totals between 30 to 40 mm are likely, with possible isolated totals up to 60 mm.

On Sunday evening conditions are forecast to temporarily ease throughout the warning area.

On Monday widespread west to northwesterly DAMAGING WINDS averaging 50 to 65 km/h with peak gusts of around 100 km/h are expected to redevelop about the far southwest in the early morning, expanding to the remainder of the warning area by the middle of the day. Winds will shift to the southwest behind this second front, with DAMAGING WINDS likely to persist throughout the afternoon and into the evening.

Conditions are then expected to ease from the west during Monday evening.

The front crossing on Sunday will produce weather that is about typical for this time of year. The front crossing on Monday is stronger, people in the southwest of WA experience fronts as windy as this about 5 times per year. This second front will be the strongest front of the year to date.

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