Track of TC 11P

Tropical Cyclone Yasi (11P), located approximately 70 nm east-southeast of Cairns, Australia, has tracked west-southwestward at 13 knots over the past six hours.

Animated infrared satellite imagery shows a 30 nm eye and the Cairns radar depicts a well-defined eyewall. The initial intensity is based on Dvorak estimates ranging from 127 to 140 knots.

TC 11P has slightly slowed in translation speed along the northern periphery of a deep layer subtropical steering ridge and is expected to make landfall south of Cairns within the next 6 hours.

The system will begin to weaken as it tracks over land and dissipate as a significant tropical cyclone by TAU 36. Maximum significant wave height is 42 feet.
