Which radars cover Karnes City?
The closest NEXRAD Doppler radar is KEWX (San Antonio, TX), about 57 miles north. 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 Karnes City | View |
|---|---|---|---|
| KEWX San Antonio, TX | 57 mi north | 4,300 ft | Good — most storms and steady rain or snow show clearly |
| KCRP Corpus Christi, TX | 80 mi south-southeast | 6,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRK Central Texas, TX | 131 mi north-northeast | 14,600 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.
