After spending some time meandering over Cuba and just off the northern coast of the island, Tropical Storm Noel began to intensify a bit and produce bursts of convection within its eastern semicircle as it started to move slowly northward during the day on 31 October 2007. AWIPS images of the GOES-12 10.7 µm IR channel (above) revealed a significant increase in the areal coverage of very cold cloud top temperatures (below -80ºC, light green enhancement); in fact, isolated IR brightness temperatures as cold as -92º C (white pixels) were noted at 04:01 UTC on 01 November.
