|Radar image of Texas dust cloud on March 18, 2014.|
Here is a satellite image about two hours later. The lower sun angle provides better contrast for seeing the dust clouds (outlined in yellow). The southern dust cloud is occurring just behind the cold front boundary and originated in eastern New Mexico. The northern dust cloud developed along the leading edge of the much cooler air and a wind shift to the north. This is the huge dust cloud, or haboob, that swept across the Panhandle.Winds were regularly gusting 35 to 45 mph with some gusts exceeding 60 mph. Visibilities were reduced to 1/4 mile or less with near "brownout" conditions.
|The leading edges of two dust clouds are evident in this visible satellite image.|
