Which radars cover Hammond?
The closest NEXRAD Doppler radar is KTYX (Montague, NY), about 48 miles south. 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 Hammond | View |
|---|---|---|---|
| KTYX Montague, NY | 48 mi south | 3,300 ft | Good — most storms and steady rain or snow show clearly |
| KCXX Burlington, VT | 125 mi east | 13,500 ft | Limited — the beam overshoots the lowest part of storms |
| KENX Albany, NY | 152 mi south-southeast | 18,600 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.
