Which radars cover Big Water?
The closest NEXRAD Doppler radar is KICX (Cedar City, UT), about 75 miles west-northwest. 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 Big Water | View |
|---|---|---|---|
| KICX Cedar City, UT | 75 mi west-northwest | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSX Flagstaff, AZ | 175 mi south | 23,300 ft | Limited — the beam overshoots the lowest part of storms |
| KESX Las Vegas, NV | 203 mi west-southwest | 30,000 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.
