Which radars cover South Dennis?
The closest NEXRAD Doppler radar is KDOX (Dover AFB, DE), about 42 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 South Dennis | View |
|---|---|---|---|
| KDOX Dover AFB, DE | 42 mi southwest | 2,800 ft | Excellent — the lowest scan sees close to the ground |
| KDIX Philadelphia, NJ | 58 mi north-northeast | 4,300 ft | Good — most storms and steady rain or snow show clearly |
| KLWX Sterling, MD | 145 mi west | 17,100 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.
