Which radars cover Monte Rio?
The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 73 miles east. 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 Monte Rio | View |
|---|---|---|---|
| KDAX Sacramento, CA | 73 mi east | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBBX Beale AFB, CA | 103 mi northeast | 10,000 ft | Limited — the beam overshoots the lowest part of storms |
| KMUX San Francisco, CA | 110 mi southeast | 11,100 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.
