Which radars cover Groveton?
The closest NEXRAD Doppler radar is KGYX (Portland, ME), about 80 miles southeast. 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 Groveton | View |
|---|---|---|---|
| KGYX Portland, ME | 80 mi southeast | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCXX Burlington, VT | 81 mi west | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBOX Boston, MA | 185 mi south | 25,500 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.
