About an hour prior to this image time, the peak wind gust at Akron, Colorado was 59 knots (68 mph). \u00a0A larger-scale view of 3 consecutive VIIRS True Color RGB images from Suomi-NPP and NOAA-20 is shown below. The data used to create these VIIRS images were downloaded and processed using the SSEC\/CIMSS Direct Broadcast ground station.<\/p>\n
