Which radars cover Post Mountain?
The closest NEXRAD Doppler radar is KBHX (Eureka, CA), about 56 miles west. 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 Post Mountain | View |
|---|---|---|---|
| KBHX Eureka, CA | 56 mi west | 4,200 ft | Good — most storms and steady rain or snow show clearly |
| KBBX Beale AFB, CA | 106 mi southeast | 10,500 ft | Limited — the beam overshoots the lowest part of storms |
| KMAX Medford, OR | 118 mi north-northeast | 12,400 ft | Limited — the beam overshoots the lowest part of storms |
