Maria intensified on 15 September 2011 to become the third hurricane of the 2011 season in the Atlantic Basin — convective bursts during this time period were seen on 4-km resolution GOES-13 10.7 µm IR images from the CIMSS Tropical Cyclones site (above).

AWIPS images of 1-km resolution MODIS 0.65 µm visible channel and 11.0 µm IR channel data (below) displayed cloud top IR brightness temperatures as cold as -84º C (darker purple color enhancement) associated with a couple of the convective bursts, and a curved convective band wrapping around the northern portion of what appeared to be the eye of Maria.
