NASA's Aqua satellite passed over the low pressure system called System 97S on Jan. 24 and observed a large area of strong thunderstorms around its center that hinted at further development. On Jan. 25, the low strengthened into the ninth tropical depression and now a tropical storm of the Southern Indian Ocean.
