Which radars cover Newcastle?
The closest NEXRAD Doppler radar is KATX (Seattle/Tacoma, WA), about 48 miles north-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 Newcastle | View |
|---|---|---|---|
| KATX Seattle/Tacoma, WA | 48 mi north-northwest | 3,400 ft | Good — most storms and steady rain or snow show clearly |
| KLGX Langley Hill, WA | 95 mi west-southwest | 8,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRTX Portland, OR | 131 mi south-southwest | 14,600 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.
