A few small, narrow areas of very low reflectivity values exist to the southwest of the radar in the left panel. In the center panel, color-shaded terrain shows local maxima in elevation in approximately the same area as the low reflectivity values. In the right panel, reflectivity is overlaid on the terrain map, and the areas of low reflectivity are aligned with the eastern sides of these protruding hills.
