Which radars cover Westwood?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 77 miles east. 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 Westwood | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 77 mi east | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDOX Dover AFB, DE | 82 mi south-southeast | 7,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLWX Sterling, MD | 111 mi southwest | 11,300 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.
