Which radars cover Corsica?
The closest NEXRAD Doppler radar is KCCX (State College, PA), about 65 miles east-southeast. 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 Corsica | View |
|---|---|---|---|
| KCCX State College, PA | 65 mi east-southeast | 5,100 ft | Good — most storms and steady rain or snow show clearly |
| KPBZ Pittsburgh, PA | 70 mi southwest | 5,600 ft | Good — most storms and steady rain or snow show clearly |
| KBUF Buffalo, NY | 124 mi north | 13,500 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.
