Which radars cover Lloyd Harbor?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 31 miles east. 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 Lloyd Harbor | View |
|---|---|---|---|
| KOKX Upton, NY | 31 mi east | 1,900 ft | Excellent — the lowest scan sees close to the ground |
| KDIX Philadelphia, NJ | 84 mi southwest | 7,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 119 mi north-northwest | 12,600 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.
