Tropical Cyclone 22S Forms Between Indonesia and Australia
Tropical Cyclone 22s, located approximately 510 nautical miles north of Learmonth, Australia, has tracked west-southwestward at 15 knots over the past 6 hours. Maximum significant wave height is 8 feet.
Animated multispectral imagery shows deep convection forming in the southwest and southeast quadrants (visible on the right side of the main image) and in the center of a well-defined circulation.
Animated water-vapor imagery shows the system developing a poleward outflow channel in the last few hours. An SSMI image shows well-defined deep convective bands wrapping around the South and into a well defined low level circulation center (LLCC).
The system is in an area of moderate vertical wind shear and high sea surface temperatures. As the system tracks to the west-southwest it will move closer to the axis of the upper level anti-cyclone and will be in an area of more favorable vertical windshear and upper-level outflow.
