CHAMBERS COUNTY, Texas (KTRK) -- If you saw a large cloud looming over Chambers County on Thursday, here's why. U.S. Fish and Wildlife Service workers responded to three wildfires at the Anahuac National Wildlife Refuge. It's unclear how the fires started. Did you see a large cloud out in Chambers Co this afternoon? Well that was a pyrocumulus cloud generated from a #wildfire! A pyrocumulus cloud forms when the heat generated is intense enough to induce convection in the atmosphere! Our GOES Satellites are also helpful in finding wildfires! The color pixels in the loop below corresponds to the temperature of the fire... and you can see the #pyrocumulus cloud streaming from the wildfire. pic.twitter.com/BHDyUJtANd— NWS Houston (@NWSHouston) December 10, 2020
