Which radars cover Ione?
The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 41 miles west-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 Ione | View |
|---|---|---|---|
| KDAX Sacramento, CA | 41 mi west-northwest | 2,700 ft | Excellent — the lowest scan sees close to the ground |
