Which radars cover Dover?
The closest NEXRAD Doppler radar is KGYX (Portland, ME), about 58 miles north-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 Dover | View |
|---|---|---|---|
| KGYX Portland, ME | 58 mi north-northeast | 4,300 ft | Good — most storms and steady rain or snow show clearly |
| KBOX Boston, MA | 86 mi south | 7,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCXX Burlington, VT | 146 mi northwest | 17,400 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.
