Areas Affected: Warning zone: Whim Creek to Dongara, including Karratha, Onslow, Exmouth, Coral Bay, Carnarvon, Denham and Geraldton, and extending inland to Pannawonica, Murchison and Yalgoo. Watch zone: South of Dongara to Jurien Bay and extending inland to Dalwallinu. Cancelled zone: None. Details of Severe Tropical Cyclone Narelle 34U at 11:00 pm AWST: Intensity: Category 4, sustained winds near the centre of 175 kilometres per hour with wind gusts to 250 kilometres per hour. Location: within 30 kilometres of 20.5 degrees South 114.4 degrees East, estimated to be 145 kilometres north northwest of Onslow and 160 kilometres north of Exmouth. Movement: southwest at 18 kilometres per hour. Severe Tropical Cyclone Narelle, category 4, is forecast to strengthen further overnight as it approaches the North West Cape. Narelle is moving southwest, roughly parallel to the Pilbara coast. Narelle is larger than usual and although the cyclone is located north of the Pilbara, gales and destructive winds are occurring over the coast. A Severe Weather Warning is also current for damaging wind gusts east of Whim Creek and for inland parts of the Pilbara. Early Friday, Narelle will turn towards the south, likely passing close to the North West Cape as a category 4 cyclone. Severe impacts will extend from the western Pilbara coast to the Gascoyne coast early morning Friday, and then extending south to Carnarvon and Denham during Friday. 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 may develop between Exmouth and Onslow overnight as Narelle moves closer to the North West Cape, and then extend down the west coast to Cape Cuvier during Friday morning. Carnarvon could see wind gusts up to 200 km/h during Friday, and wind gusts up to 180 km/h could extend to Denham late Friday or early Saturday. DESTRUCTIVE WIND GUSTS in excess of 125 km/h are occurring along the Pilbara coast between Mardie and west of Onslow, and are expected to extend west to Exmouth overnight. DESTRUCTIVE WIND GUSTS in excess of 125 km/h are expected to extend south to Carnarvon and then to Denham during Friday morning and afternoon, and may extend to Kalbarri and inland parts later on Friday and possibly as far south as Morawa Saturday morning. GALES with DAMAGING WIND GUSTS to 120 km/h are occurring near the coast between Whim Creek and Exmouth. Gales will extend further south to Kalbarri and inland, possibly as far east as Murchison, during Friday. Gales may extend south to Jurien Bay and inland to Dalwallinu during Saturday morning. HEAVY RAINFALL which may lead to FLASH FLOODING is possible in western parts of the Pilbara and Gascoyne as Narelle moves past. Areas of INTENSE RAINFALL that may lead to SEVERE FLASH FLOODING is likely to develop about the western Pilbara west of about Onslow overnight and Friday morning, before extending further south into the northwestern Gascoyne later Friday morning. Coastal residents between Onslow and Denham are specifically warned of a DANGEROUS STORM TIDE as the cyclone moves south down the Gascoyne coast. Tides are likely to rise significantly above the normal high tide, with DAMAGING WAVES and DANGEROUS FLOODING. Tides will be higher than normal between Port Hedland and Onslow. LARGE WAVES may produce MINOR FLOODING of low-lying coastal areas. Recommended Action: DFES advises: Ensure you know what to do in a cyclone.
