TIDES between Yanchep and Mandurah will be higher than expected as a cold front moves through southwest parts of WA and continues moving towards the north and east this afternoon.
The Bureau of Meteorology said the front was not as strong as the weather system which moved through Perth and western parts of WA last Sunday and Monday, but winds could cause damage to property and make road conditions hazardous.
Damaging winds, averaging 60 to 70 km/h with peak gusts to around 100 km/h are possible, particularly in coastal parts south of Mandurah and could cause damage to homes and property.
Wind gusts of 104km/h at Gooseberry Hill at 12.47pm WST, 93km/h at Garden Island at 9.05am WST and 93km/h at Cape Leeuwin at 8.26am WST have been reported.
Conditions will ease from the west during the evening and overnight.
Squally thunderstorms are possible throughout the warning area with the passage of the front, with small hail also possible south of Bunbury to Katanning behind the front this evening.
Heavy rainfall is possible with rainfall totals of 40mm to 50mm in the Perth hills and parts of the Southwest District.
Heavy showers and thunderstorms could reduce visibility and make driving conditions hazardous.
Tides between Mandurah and Albany are likely to rise above the normal high tide mark with very rough seas and potential flooding of low-lying coastal areas.
Tides along the lower west coast have been observed at 0.25m to 0.5m above the predicted tide.
Damaging surf conditions are possible which could cause beach erosion about the Southwest Capes and along the south coast to Albany.
