The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft captured this infrared image of Tropical Cyclone Yasi at 11:11 p.m. EST February 2, 2011 (04:11 UTC). Yasi has moved further inland and is gradually weakening. At 10 p.m. EST Feb. 2, the storm had maximum sustained winds of 60 knots (111 kilometers per hour, or about 70 miles per hour, equivalent to a strong tropical storm. According to the Joint Typhoon Warning Center, despite crossing Australia's Great Dividing Range, the system has maintained clear organization, as seen in the AIRS image. The AIRS data show that the storm's cloud tops have warmed substantially and there has been a significant decrease in convection. The storm will continue on its course until dissipation deep in the Australian interior.
