**Cyclone Sean Intensifies to Category 3 Storm Off WA: Record-breaking Rainfall**
Tropical Cyclone Sean has intensified to a category three storm off the northern coast of Western Australia, causing record-breaking rainfall and posing a severe threat to residents in the region. The Bureau of Meteorology has issued an upgraded alert for the Pilbara, urging immediate shelter as the cyclone is expected to impact the western coast between Mardie and Ningaloo today.
Record-breaking Rainfall and Intense Winds
Karratha experienced a staggering 274.4mm of rainfall in the 24 hours leading up to 9am, marking the wettest day on record in any month. This surpasses the town’s entire monthly January rainfall record of 263.4mm. The storm is brewing winds of up to 130km/h, with further strengthening anticipated as it moves westward, parallel to the Pilbara coast at a speed of 17km/h. Once the cyclone progresses west of the Pilbara, it is expected to veer to the south-west and move away from the coast.
Emergency Warnings and Precautions
The WA Department of Fire and Emergency Services has released an emergency warning for residents from Thevernard Island to Ningaloo, including Exmouth and North West Cape, advising immediate shelter indoors as evacuating is no longer an option. The warning highlights the imminent danger to lives and homes, emphasizing the urgency of taking immediate action. Barrow Island and Mardie to Ningaloo are currently under a cyclone watch and act warning, while Whim Creek to Mardie is advised to stay informed.
Forecasted Impact and Additional Precautions
As the cyclone progresses westward, a storm tide is projected between Onslow and Exmouth during this afternoon’s high tide. This could potentially result in minor flooding along the foreshore, prompting nearby residents to take necessary precautions to safeguard their properties. Although the storm is predicted to intensify to a category four, it is expected to veer significantly off the coast by then.
