On Nov. 13, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite gathered data on Tropical Cyclone Gaja. Gaja appeared somewhat elongated and had bands of thunderstorms wrapping into the center. Gaja appeared to extend over much of the Bay of Bengal in satellite imagery.

The Joint Typhoon Warning Center or JTWC noted "animated multispectral satellite imagery shows expansive but disorganized and fragmented rain bands loosely wrapping into an obscured low level circulation with the deep central convection sheared northeastward."
