Which radars cover Tacna?
The closest NEXRAD Doppler radar is KYUX (Yuma, AZ), about 43 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 Tacna | View |
|---|---|---|---|
| KYUX Yuma, AZ | 43 mi west-southwest | 2,900 ft | Excellent — the lowest scan sees close to the ground |
