Which radars cover Riverhead?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 11 miles west-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 Riverhead | View |
|---|---|---|---|
| KOKX Upton, NY | 11 mi west-southwest | 600 ft | Excellent — the lowest scan sees close to the ground |
| KBOX Boston, MA | 106 mi northeast | 10,500 ft | Limited — the beam overshoots the lowest part of storms |
| KDIX Philadelphia, NJ | 115 mi southwest | 11,900 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.
