\"GOES-15<\/a><\/p>\n

The West Fork fire complex continued to burn at an explosive rate on 21 June<\/strong><\/a> — a comparison of GOES-15 (left panels)<\/em> and GOES-13 (right panels)<\/em> 0.63 \u00c2\u00b5m visible channel and 3.9 \u00c2\u00b5m shortwave IR channel images ((above; click image to play animation)<\/strong><\/em> showed two very large smoke plumes with pyrocumulonimbus (pyroCb) clouds forming near the source of the fires.<\/p>\n

A layer of high cirrus clouds began to move over the fire region later in the afternoon and early evening (01 UTC satellite images<\/strong><\/a>), masking the view of the pyroCb clouds and smoke plumes; however, the fire “hot spots” (red enhanced pixels)<\/em> could still be sensed through the veil of high clouds. At around 01:04 UTC, a fantastic photo (photo 2<\/strong><\/a> | photo 3<\/strong><\/a> | photo 4<\/strong><\/a>) of the fire was taken by Luis Rosa (NWS San Juan Puerto Rico)<\/strong><\/a> from a passenger aircraft flying at 35,000 feet which showed the northernmost pyroCb cloud — likely the Papoose Fire –\u00c2\u00a0 beneath the cirrus cloud layer (below)<\/strong><\/em>.<\/p>\n
