Which radars cover Tennant?
The closest NEXRAD Doppler radar is KMAX (Medford, OR), about 54 miles 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 Tennant | View |
|---|---|---|---|
| KMAX Medford, OR | 54 mi northwest | 3,900 ft | Good — most storms and steady rain or snow show clearly |
| KBHX Eureka, CA | 145 mi west-southwest | 17,100 ft | Limited — the beam overshoots the lowest part of storms |
