Which radars cover Canton?
The closest NEXRAD Doppler radar is KTYX (Montague, NY), 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 Canton | View |
|---|---|---|---|
| KTYX Montague, NY | 64 mi south-southwest | 5,000 ft | Good — most storms and steady rain or snow show clearly |
| KCXX Burlington, VT | 99 mi east | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 150 mi south-southeast | 18,100 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.
