Which radars cover Mount Gretna?
The closest NEXRAD Doppler radar is KCCX (State College, PA), about 93 miles west-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 Mount Gretna | View |
|---|---|---|---|
| KCCX State College, PA | 93 mi west-northwest | 8,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLWX Sterling, MD | 103 mi south-southwest | 10,100 ft | Limited — the beam overshoots the lowest part of storms |
| KDIX Philadelphia, NJ | 111 mi east | 11,300 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.
