Which radars cover Rancho Mission Viejo?
The closest NEXRAD Doppler radar is KSOX (Santa Ana Mountains, CA), about 21 miles north-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 Rancho Mission Viejo | View |
|---|---|---|---|
| KSOX Santa Ana Mountains, CA | 21 mi north-northwest | 1,200 ft | Excellent — the lowest scan sees close to the ground |

| KEYX Edwards AFB, CA | 109 mi north | 11,000 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.
