Which radars cover Westport?
The closest NEXRAD Doppler radar is KABR (Aberdeen, SD), about 14 miles south-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 Westport | View |
|---|---|---|---|
| KABR Aberdeen, SD | 14 mi south-southeast | 700 ft | Excellent — the lowest scan sees close to the ground |
| KBIS Bismarck, ND | 133 mi northwest | 15,000 ft | Limited — the beam overshoots the lowest part of storms |
| KMVX Grand Forks, ND | 141 mi north-northeast | 16,500 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.
