NASA sees Cyclone Victoria developing an eyeApril 11, 2013 in Earth / Earth Sciences
Cyclone Victoria continued to intensify overnight from April 9 to April 10, and imagery from NASA's Aqua satellite showed a tighter storm circulation and a possible eye developing.
On April 10, 2013 at 0300 UTC, Victoria had maximum sustained winds near 60 knots (69 mph/111 kph). Victoria was located near 15.2 south and 103.8 east, about 735 nautical miles northwest of Learmonth, Australia. Victoria was moving to the south-southeast at 8 knots (9 mph/15 kph).
NASA's Aqua satellite passed over Tropical Cyclone Victoria on April 10 at 0705 UTC (3:05 a.m. EDT). The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard Aqua captured this visible image that showed a rounded Tropical Cyclone Victoria with strong thunderstorms around the center of circulation, moving through the Southern Indian Ocean.
According to the Joint Typhoon Warning Center (JTWC), Victoria is in an area of low wind shear and warm waters. However, an approaching mid-latitude trough of low pressure will increase wind shear and as Victoria heads further south, the waters will cool.
