Which radars cover South Windham?
The closest NEXRAD Doppler radar is KGYX (Portland, ME), about 13 miles 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 South Windham | View |
|---|---|---|---|
| KGYX Portland, ME | 13 mi northeast | 700 ft | Excellent — the lowest scan sees close to the ground |
| KBOX Boston, MA | 128 mi south-southwest | 14,200 ft | Limited — the beam overshoots the lowest part of storms |
| KCXX Burlington, VT | 146 mi west-northwest | 17,400 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.
