Which radars cover Four Corners?
The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 54 miles north. 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 Four Corners | View |
|---|---|---|---|
| KRTX Portland, OR | 54 mi north | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KLGX Langley Hill, WA | 161 mi north-northwest | 20,300 ft | Limited — the beam overshoots the lowest part of storms |
| KMAX Medford, OR | 197 mi south | 28,500 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.
