Which radars cover Delmar?
The closest NEXRAD Doppler radar is KDOX (Dover AFB, DE), about 25 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 Delmar | View |
|---|---|---|---|
| KDOX Dover AFB, DE | 25 mi north-northeast | 1,500 ft | Excellent — the lowest scan sees close to the ground |
| KLWX Sterling, MD | 110 mi west-northwest | 11,200 ft | Limited — the beam overshoots the lowest part of storms |
| KDIX Philadelphia, NJ | 119 mi north-northeast | 12,500 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.
