Which radars cover Alpha?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 63 miles 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 Alpha | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 63 mi southeast | 4,900 ft | Good — most storms and steady rain or snow show clearly |
| KBGM Binghamton, NY | 115 mi north-northwest | 11,900 ft | Limited — the beam overshoots the lowest part of storms |
| KOKX Upton, NY | 121 mi east | 12,900 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.
