Which radars cover Groveland?

| Radar | Distance | Lowest beam over Groveland | View |
|---|---|---|---|
| KDAX Sacramento, CA | 91 mi west-northwest | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |

| KHNX San Joaquin Valley, CA | 110 mi south-southeast | 11,100 ft | Limited — the beam overshoots the lowest part of storms |
