During Friday afternoon a secondary cold front will approach the south west corner of the State. The first front is likely to cause widespread damaging winds to 100 kilometres per hour that could result in damage to homes and property. In isolated areas dangerous gusts in excess of 125 kilometres per hour could cause significant damage or destruction to homes and property. Damaging winds are likely to develop along the west coast from Kalbarri to Walpole between 12am and 2am and extend inland to remaining areas by midday Friday. The first front is also likely to cause heavy rainfall that may lead to flash flooding in parts of the warning area. The passage of the secondary front is likely to cause widespread damaging winds to 100 kilometres per hour that could result in damage to homes and property. Damaging winds will extend to south west of a line Dongara to Paynes Find to Israelite Bay by the evening.
