Which radars cover Angwin?
The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 42 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 Angwin | View |
|---|---|---|---|
| KDAX Sacramento, CA | 42 mi east | 2,800 ft | Excellent — the lowest scan sees close to the ground |
| KBBX Beale AFB, CA | 77 mi northeast | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMUX San Francisco, CA | 103 mi south-southeast | 10,000 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.
