NORTHERN COLORADO RADAR

The WSR-88D radar used here is located in Cheyenne, WY (CYS), and the images are generated
from raw Level 2 data using only the lowest scan elevation available. Images are updated every 4-10 minutes, depending on the radar's scanning mode (VCP). See below for details.

The timeliness of the most current image depends on the radar scanning mode, plus a fixed processing
time. The chart below gives approximate optimal delay times between the actual base scan and the
image being updated. You can force this webpage to refresh as often as you wish (SHIFT+reload),
but it will automatically refresh every 3 minutes.

The elevation of detected features above the ground varies with distance from the radar site
due to the combined effects of the curvature of the Earth, the radar beam tilt, and the topography.

Circular range rings are shown in green every 20 miles from the radar location.
State, US, and interstate highways are drawn in gray.
Details within Fort Collins, CO include major roads, Horsetooth Reservoir, and the two dark red dots are the
locations of CSU Main Campus (east) and CSU Foothills Campus (west).
