Which radars cover Cascadia?
The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 94 miles north-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 Cascadia | View |
|---|---|---|---|
| KRTX Portland, OR | 94 mi north-northwest | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMAX Medford, OR | 160 mi south | 20,200 ft | Limited — the beam overshoots the lowest part of storms |
| KPDT Pendleton, OR | 200 mi east-northeast | 29,100 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.
