Which radars cover Isleton?
The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 24 miles north. 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 Isleton | View |
|---|---|---|---|
| KDAX Sacramento, CA | 24 mi north | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KMUX San Francisco, CA | 71 mi south-southwest | 5,800 ft | Good — most storms and steady rain or snow show clearly |
| KBBX Beale AFB, CA | 92 mi north | 8,500 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.
