Which radars cover Winthrop?
The closest NEXRAD Doppler radar is KCXX (Burlington, VT), about 83 miles east-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 Winthrop | View |
|---|---|---|---|
| KCXX Burlington, VT | 83 mi east-southeast | 7,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KTYX Montague, NY | 84 mi south-southwest | 7,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 158 mi south-southeast | 19,700 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.
