Which radars cover Granby?
The closest NEXRAD Doppler radar is KFTG (Denver/Boulder, CO), about 75 miles east-southeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Granby | View |
|---|---|---|---|
| KFTG Denver/Boulder, CO | 75 mi east-southeast | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCYS Cheyenne, WY | 95 mi northeast | 8,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGJX Grand Junction, CO | 141 mi west-southwest | 16,300 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
