Which radars cover Montclair?
The closest NEXRAD Doppler radar is KSOX (Santa Ana Mountains, CA), about 18 miles south-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 Montclair | View |
|---|---|---|---|
| KSOX Santa Ana Mountains, CA | 18 mi south-southeast | 1,000 ft | Excellent — the lowest scan sees close to the ground |
| KEYX Edwards AFB, CA | 71 mi north | 5,800 ft | Good — most storms and steady rain or snow show clearly |
| KVTX Los Angeles, CA | 88 mi west-northwest | 7,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
