Which radars cover Greenville?
The closest NEXRAD Doppler radar is KCBW (Caribou, ME), about 94 miles east-northeast. 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 Greenville | View |
|---|---|---|---|
| KCBW Caribou, ME | 94 mi east-northeast | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGYX Portland, ME | 114 mi south-southwest | 11,700 ft | Limited — the beam overshoots the lowest part of storms |
| KCXX Burlington, VT | 187 mi west-southwest | 26,200 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.
