Which radars cover Niantic?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 47 miles southwest. 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 Niantic | View |
|---|---|---|---|
| KOKX Upton, NY | 47 mi southwest | 3,200 ft | Good — most storms and steady rain or snow show clearly |
| KBOX Boston, MA | 70 mi northeast | 5,700 ft | Good — most storms and steady rain or snow show clearly |
| KENX Albany, NY | 130 mi northwest | 14,400 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.
