Which radars cover Occoquan?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 24 miles north-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 Occoquan | View |
|---|---|---|---|
| KLWX Sterling, MD | 24 mi north-northwest | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KDOX Dover AFB, DE | 99 mi east | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KAKQ Wakefield, VA | 118 mi south | 12,400 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.
