Severe winter storm hits southern WA with destructive winds, rain, and coastal hazards
Consensus Summary
Southern Western Australia is bracing for a severe winter storm system expected to bring destructive winds of up to 125 km/h, heavy rainfall, and coastal hazards over the long weekend. The Bureau of Meteorology (BOM) has issued warnings for the South West Land Division, including major cities like Perth, Margaret River, Bunbury, and Mandurah, with impacts extending from Kalbarri in the northwest to Israelite Bay in the southeast. The storm is described as unusually strong, potentially the strongest of the year, with waves reaching 8 metres offshore and high tides increasing coastal erosion risks. Both sources agree on the urgency for residents to secure loose objects, trim branches, and prepare emergency kits. While ABC highlights the storm's intensity and regional preparedness, NEWSCOMAU adds a specific risk of short-lived tornadoes from Saturday night to Sunday morning, a detail not mentioned in ABC's report. The storm is expected to ease as it moves eastward, leaving the rest of Australia with milder conditions.

- Assistant Commissioner Paul Carr advised long weekend travellers to avoid areas with heavy tree foliage along road verges or camping under trees due to potential hazards.
