GOES-16 (GOES-East) True Color Red-Green-Blue (RGB) images created using Geo2Grid (above) showed plumes of blowing dust originating from dry beds of the Río Grande O Guapay and Río Parapetí in southern Bolivia on 04 July 2020. Strong northerly winds developed across that region, just east of the axis of a deepening trough of low pressure.

VIIRS True Color RGB images from Suomi NPP and NOAA-20 as visualized using RealEarth (below) provided a more detailed view at the blowing dust plumes.

A plot of surface report data from Viro Viru International Airport, Santa Cruz de la Sierra — located just north of the 2 dry river beds — showed northerly winds gusting as high as 36 knots at 20 UTC (below).

Thanks to Santiago Gassó for pointing out these dust features.
