Which radars cover Dayton?
The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 35 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 Dayton | View |
|---|---|---|---|
| KRTX Portland, OR | 35 mi north | 2,200 ft | Excellent — the lowest scan sees close to the ground |
| KLGX Langley Hill, WA | 140 mi north-northwest | 16,200 ft | Limited — the beam overshoots the lowest part of storms |
| KPDT Pendleton, OR | 207 mi east | 31,100 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.
