GOES-13 10.7 µm IR images from the CIMSS Tropical Cyclones site (above) showed increasing convective banding within the eastern semicircle of Tropical Storm Nate as the system was undergong a period of intensification on 10 September 2011.

Deep layer wind shear was light over the region (below), which was a factor that aided in the intensification of the tropical cyclone.

The GOES-13 satellite had been placed into Super Rapid Scan Operations (SRSO), providing bursts of 1-minute interval imagery. A sample of GOES-13 0.63 µm visible channel SRSO images (below; click image to play animation) showed the development of the convective bands wrapping around the center of the tropical cyclone. Early in the animation, you can also see the hazy appearance of the water to the east of Nate (off the west coast of the Yucatan Peninsula of Mexico) — this enhanced turbidity was the result of persistent strong southerly winds across those waters as Nate developed and moved very slowly across the region.
