Which radars cover East Islip?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 19 miles east-northeast. 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 East Islip | View |
|---|---|---|---|
| KOKX Upton, NY | 19 mi east-northeast | 1,100 ft | Excellent — the lowest scan sees close to the ground |
| KDIX Philadelphia, NJ | 84 mi southwest | 7,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBOX Boston, MA | 136 mi northeast | 15,500 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.
