Which radars cover Gaston?
The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 21 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 Gaston | View |
|---|---|---|---|
| KRTX Portland, OR | 21 mi north-northeast | 1,200 ft | Excellent — the lowest scan sees close to the ground |
| KLGX Langley Hill, WA | 125 mi north-northwest | 13,600 ft | Limited — the beam overshoots the lowest part of storms |
| KATX Seattle/Tacoma, WA | 193 mi north | 27,600 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.
