Likely a devastating landfall of Severe Tropical Cyclone #Damien has occurred in the last hours, potentially as a Category 4 system. Although the official 00 UTC update held it at 95 knots, Dvorak estimates were solid at 105-110 knots during the last 3 hours prior to landfall near Dampier and Karratha, Western Australia. Damien is delivering violent and destructive winds with gusts above 200 km/h, torrential rains with flooding and major storm surge on the coast. It will now weaken while drifting inland into Western Australia.
Karratha airport reported 957.5 mbar pressure in the eye of the cyclone, while the winds within the eyewall were reported at 80 knots, gusting to 100 knots!
IR and VIS scans:
#Damien has recently made a bullseye landfall on Karratha and Dampier. While satellite imagery suggests an intensity close to Cat 4 status, surface observations "only" show a solid Category 2 storm. Karratha reported a low pressure of 956mb in the eye and maximum winds of 80kts pic.twitter.com/nPjc0vwwO9

High-res radar imagery during landfall:
Advanced Dvorak Technique (ADT) estimated Damien has near 110 kt maximum sustained winds and pressure around 946 mbar. Dvorak raw T number of 5.9! 70-85 miles wind radii of 50-knot winds is expanding around center, and 30-50 miles with radii of hurricane-force 64-knot winds!
Tropical Cyclone Damien will not gradually weaken while moving further inland across Western Australia.
