Tropical Cyclone Rusty (17S) Near Coast of Western Australia – February 24th, 201318.6S 116.0E
Tropical Cyclone Rusty (17S), located approximately 160 nm north of Port Hedland, Australia, has tracked south-southwestward at 03 knots over the past six hours.
Animated infrared (IR) satellite imagery depicts a rapidly consolidating system with a 20-nm eye. An AMSU image and Port Hedland radar depict an intense spiral band extending from Broome westward over Port Hedland then wrapping into the western quadrant of the system.
Surface observations along the northwest coast of Australia indicate persistent gale-force winds associated with this spiral band. Based on the eye fixes, there is high confidence in the initial position. The initial intensity is assessed at 60 knots, higher than the Dvorak intensity estimates of 55 knots, based on the impressive structure evident in satellite, microwave and radar imagery.
