Which radars cover Mont Alto?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 60 miles south. 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 Mont Alto | View |
|---|---|---|---|
| KLWX Sterling, MD | 60 mi south | 4,500 ft | Good — most storms and steady rain or snow show clearly |
| KCCX State College, PA | 78 mi north-northwest | 6,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDOX Dover AFB, DE | 133 mi east-southeast | 15,000 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.
