Which radars cover Ahtanum?
The closest NEXRAD Doppler radar is KPDT (Pendleton, OR), about 103 miles southeast. 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 Ahtanum | View |
|---|---|---|---|
| KPDT Pendleton, OR | 103 mi southeast | 10,100 ft | Limited — the beam overshoots the lowest part of storms |
