Which radars cover Lake Seneca?
The closest NEXRAD Doppler radar is KIWX (Fort Wayne, IN), about 58 miles west-southwest. 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 Lake Seneca | View |
|---|---|---|---|
| KIWX Fort Wayne, IN | 58 mi west-southwest | 4,400 ft | Good — most storms and steady rain or snow show clearly |
