Which radars cover Jacumba?
The closest NEXRAD Doppler radar is KNKX (San Diego, CA), about 53 miles west-northwest. 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 Jacumba | View |
|---|---|---|---|
| KNKX San Diego, CA | 53 mi west-northwest | 3,900 ft | Good — most storms and steady rain or snow show clearly |
| KYUX Yuma, AZ | 90 mi east | 8,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KSOX Santa Ana Mountains, CA | 117 mi northwest | 12,200 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.
