Which radars cover Piermont?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 56 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 Piermont | View |
|---|---|---|---|
| KOKX Upton, NY | 56 mi east-southeast | 4,100 ft | Good — most storms and steady rain or snow show clearly |
| KDIX Philadelphia, NJ | 80 mi south-southwest | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 107 mi north | 10,700 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.
