After the visible images on the left panels faded to black during the night-time hours, the shortwave IR images on the right panels showed that many of the fire “hot spots” (denoted by the darker black pixels) continued to grow during the night.<\/p>\n

MTSAT-2 10.8 \u00c2\u00b5m longwave IR channel images (below; click image to play animation; also available as an MP4 animation<\/a>)<\/strong><\/em> indicated that cloud-top IR brightness temperatures associated with the rapidly-growing pyroCb cloud became as cold as -38.7\u00c2\u00ba C (lighter green color enhancement)<\/em> at 07:32 UTC. Other areas of cold-topped thunderstorms developed near the coast, likely initiated by sea breeze and\/or local terrain influences. Surface reports ploted on the IR images revealed very hot temperatures: for example, it was 109\u00c2\u00ba F (42.8\u00c2\u00ba C) at Melbourne Essondon (station identifier YMEN)<\/em> at 04 UTC.<\/p>\n
