NASA Satellite Data Gives System 96S A Fair Shot At Becoming Tropical Cyclone
A low pressure area located a couple of hundred miles northwest of Western Australia appears in a better position for development into a tropical cyclone according to infrared NASA satellite imagery. Infrared imagery from NASA's Aqua satellite shows some strong convection in the low, named System 96S.
When Aqua passed over System 96S on Feb. 9 at 17:47 UTC (12:47 p.m. EST), the Atmospheric Infrared Sounder (AIRS) instrument showed some strong convection and strong thunderstorms with very cold cloud-top temperatures around the center of circulation. Those cloud top temperatures were as cold as or colder than -63 Fahrenheit/-52 Celsius indicating strong convection, strong thunderstorms, and heavy rainfall. The imagery suggests that the convection is consolidating and increasing around the low's center.
At 2300 UTC on Feb. 9, (6 p.m. EST) System 96S had maximum sustained surface winds near 20 to 25 knots (23 mph/ 37 kmh to 29 mph/46 kmh). It was located about 260 miles (418 km) northwest of Barrow Island, Australia near 17.7 South and 112.2 East. Residents of Western Australia are keeping a close eye on this system for development.
