Which radars cover Dunthorpe?
The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 24 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 Dunthorpe | View |
|---|---|---|---|
| KRTX Portland, OR | 24 mi northwest | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KLGX Langley Hill, WA | 135 mi north-northwest | 15,300 ft | Limited — the beam overshoots the lowest part of storms |
| KPDT Pendleton, OR | 185 mi east | 25,600 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
