A Severe Weather Warning is also current for damaging wind gusts east of Whim Creek and for inland parts of the Pilbara. On Saturday, Narelle is expected to be weakening as it moves quickly to the south southeast, with impacts extending to the Central West and then further inland and south across the South West Land Division. During Saturday the strongest winds are expected to be on the eastern side of the system. Hazards: VERY DESTRUCTIVE WIND GUSTS up to 275 km/h are occurring over coastal parts between Exmouth and Onslow and are expected to extend south to Coral Bay early this morning as Narelle moves over the North West Cape, before extending down the west coast to Cape Cuvier during this morning.

DESTRUCTIVE WIND GUSTS in excess of 125 km/h are occurring along the west Pilbara coast between east of Onslow and the North West Cape, including Exmouth and will extend south along the Ningaloo coast early this morning. DESTRUCTIVE WIND GUSTS in excess of 125 km/h are expected to extend south to Carnarvon and then to Denham during this morning and afternoon, and may extend to Kalbarri and inland parts later today and possibly as far south as Morawa Saturday morning. GALES with DAMAGING WIND GUSTS to 120 km/h are occurring in coastal areas between Whim Creek and Coral Bay, including Exmouth and are possible over adjacent inland areas to Pannawonica. Gales will extend south Carnarvon and Denham this morning and further south to Kalbarri and inland, possibly as far east as Murchison, during today. Gales may extend south to Jurien Bay and inland to Dalwallinu during Saturday morning. HEAVY RAINFALL which may lead to FLASH FLOODING is possible over western parts of the Pilbara, Gascoyne and Central West as Narelle moves past.
