Which radars cover Nassau?
The closest NEXRAD Doppler radar is KENX (Albany, NY), about 24 miles west-northwest. 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 Nassau | View |
|---|---|---|---|
| KENX Albany, NY | 24 mi west-northwest | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KOKX Upton, NY | 120 mi south-southeast | 12,800 ft | Limited — the beam overshoots the lowest part of storms |
| KBGM Binghamton, NY | 123 mi west | 13,300 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.
