Which radars cover Los Osos?
The closest NEXRAD Doppler radar is KVBX (Vandenberg AFB, CA), about 40 miles 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 Los Osos | View |
|---|---|---|---|
| KVBX Vandenberg AFB, CA | 40 mi southeast | 2,700 ft | Excellent — the lowest scan sees close to the ground |
| KHNX San Joaquin Valley, CA | 96 mi northeast | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KVTX Los Angeles, CA | 112 mi east-southeast | 11,400 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.
