Which radars cover Happy Valley?
The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 29 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 Happy Valley | View |
|---|---|---|---|
| KRTX Portland, OR | 29 mi northwest | 1,800 ft | Excellent — the lowest scan sees close to the ground |
