Which radars cover Lebanon?
The closest NEXRAD Doppler radar is KCXX (Burlington, VT), about 76 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 Lebanon | View |
|---|---|---|---|
| KCXX Burlington, VT | 76 mi northwest | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGYX Portland, ME | 101 mi east | 9,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 117 mi southwest | 12,200 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.
