Massive Dust Storm hits Onslow

Tropical Cyclone Narelle is spinning out to sea west of Western Australia as it reached Category 3 status with wind gusts near center at 285 km/h (177 mph). Narelle is moving slightly southwestward and will maintain that bearing for the next few days before heading due south and rounding the continent’s southwest in the coming days. The storm’s bands to the southeast are drawing desert sand off land out into the Indian Ocean. Meanwhile, Australia is battering with catastrophic bushfires after unprecedented record-high temperatures. The high temperatures and dryness of the region create prime conditions for fires.
According to latest Joint Typhoon Warning Center (JTWC), TC Narelle is located approximately 335 nm north-northwest of Learmonth, Australia and is moving west-southwestward at speed of 6 knots. Narelle is tracking along the northwestern periphery of a deep-layered subtropical ridge anchored over south-central Australia. Narelle has peaked in intensity and should gradually weaken mainly due to increasing vertical wind shear and cooling sea surface temperatures.
