Which radars cover St. Martin?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 70 miles 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 St. Martin | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 70 mi southeast | 5,700 ft | Good — most storms and steady rain or snow show clearly |
| KDLH Duluth, MN | 149 mi northeast | 18,100 ft | Limited — the beam overshoots the lowest part of storms |
| KFSD Sioux Falls, SD | 167 mi southwest | 21,600 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.
