Which radars cover Duvall?
The closest NEXRAD Doppler radar is KATX (Seattle/Tacoma, WA), about 40 miles 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 Duvall | View |
|---|---|---|---|
| KATX Seattle/Tacoma, WA | 40 mi northwest | 2,600 ft | Excellent — the lowest scan sees close to the ground |
| KLGX Langley Hill, WA | 109 mi west-southwest | 10,900 ft | Limited — the beam overshoots the lowest part of storms |
| KRTX Portland, OR | 147 mi south-southwest | 17,600 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.
