Which radars cover Alsea?
The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 97 miles north-northeast. 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 Alsea | View |
|---|---|---|---|
| KRTX Portland, OR | 97 mi north-northeast | 9,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMAX Medford, OR | 165 mi south-southeast | 21,200 ft | Limited — the beam overshoots the lowest part of storms |
| KLGX Langley Hill, WA | 191 mi north | 26,900 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.
