Hazards:
VERY DESTRUCTIVE WIND GUSTS to 195 km/h are possible over coastal parts of the Pilbara to the west of Dampier this morning. Very destructive wind gusts may extend along the coast to Onslow during Sunday, if Mitchell tracks closer to the coast than currently forecast. Very destructive wind gusts may develop along the Exmouth Gulf as the core of Mitchell approaches the coast on Sunday evening.
DESTRUCTIVE WIND GUSTS to 160 km/h are possible around Dampier, extending west towards Onslow during the day and extending to Exmouth during Sunday evening.
GALES with DAMAGING WIND GUSTS to 120 km/h are occurring along coastal areas between Roebourne and Mardie, possibly extending inland to Pannawonica later on Sunday morning. GALES with DAMAGING WIND GUSTS to 120 km/h are forecast to extend west to Onslow and Exmouth on Sunday afternoon and evening, and then extend further south to Cape Cuvier and inland parts of the western Pilbara on Sunday night.
Widespread moderate to HEAVY RAINFALL which may lead to FLASH FLOODING is likely over the west Pilbara coast, extending to the west Gascoyne region on Monday. Local areas of INTENSE rainfall leading to SEVERE FLASH FLOODING may develop around the west Pilbara coast west of Karratha this morning.
ABNORMALLY HIGH TIDES could cause SERIOUS FLOODING in the Karratha region early this morning, and then in the Onslow region this afternoon.
Elsewhere on the west Pilbara coast including Exmouth, tides are likely to rise above the normal high tide mark on Sunday which may produce FLOODING of low-lying coastal areas.
