Which radars cover San Luis?
The closest NEXRAD Doppler radar is KYUX (Yuma, AZ), about 4 miles east. 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 San Luis | View |
|---|---|---|---|
| KYUX Yuma, AZ | 4 mi east | 200 ft | Excellent — the lowest scan sees close to the ground |
| KNKX San Diego, CA | 138 mi west-northwest | 15,900 ft | Limited — the beam overshoots the lowest part of storms |
| KIWA Phoenix, AZ | 186 mi east-northeast | 25,800 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.
