Which radars cover Seneca?
The closest NEXRAD Doppler radar is KPBZ (Pittsburgh, PA), about 64 miles south-southwest. 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 Seneca | View |
|---|---|---|---|
| KPBZ Pittsburgh, PA | 64 mi south-southwest | 5,000 ft | Good — most storms and steady rain or snow show clearly |
| KCCX State College, PA | 94 mi east-southeast | 8,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCLE Cleveland, OH | 112 mi west | 11,400 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.
