Posted in Non-US Weather, Tropical Weather at 10:24 am by Rebekah

Category 5 Tropical Cyclone Yasi (equivalent of a Cat. 4 on the Saffir-Simpson scale) made landfall near Mission Beach, between Innisfail and Cardwell, Queensland about an hour and a half ago (12:30 am local time).

Here is a summary of the cyclone’s landfall and expected impacts.

Even once the winds slow down some, Yasi will bring a lot of rain to northeastern Queensland; the cyclone also looks like it will stall for a bit in the mountains, allowing even more rain to fall. Models show that the area could receive as much as a foot of rain, and some localized areas could even receive 2 feet or more of rain.
