Cyclone Gino Winds Up To Wind Down Later Seen By Nasa
NASA's Aqua satellite passed over Cyclone Gino as the storm continues to wind up in the southern Indian Ocean, consolidating and strengthening. Infrared data shows the storm has strengthened but it is headed for cooler waters which will weaken it in coming days.
On Feb. 12 at 1500 UTC (10 a.m. EST), Cyclone Gino's maximum sustained winds had increased to 75 knots (86.3 mph/138.9 kph) making the storm a category one hurricane. Gino was centered near 17.1 south latitude and 79.5 east longitude, about 700 nautical miles (805.5 miles/1,296 km) southeast of Diego Garcia.
Gino has been moving to the south-southwest at 10 knots (11.5 mph/18.5 kph), around the northwestern edge of a subtropical ridge (elongated area) of high pressure.
AIRS data shows that the sea surface temperatures around Gino are currently favorable for further development because they're around a warm 28 degrees Celsius (82.4 Fahrenheit). However, as Gino moves further south-southwest, those sea surface temperatures will drop, making it more difficult for the tropical cyclone to maintain intensity.
In addition, wind shear is expected to increase over the next three days as Gino moves further south. The Joint Typhoon Warning Center expects Gino to transition to a cold core low pressure area by Feb. 15.
