Which radars cover Norco?
The closest NEXRAD Doppler radar is KHDC (Hammond, LA), about 36 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 Norco | View |
|---|---|---|---|
| KHDC Hammond, LA | 36 mi north | 2,300 ft | Excellent — the lowest scan sees close to the ground |
| KLIX New Orleans, LA | 42 mi northeast | 2,800 ft | Excellent — the lowest scan sees close to the ground |
| KMOB Mobile, AL | 137 mi east-northeast | 15,800 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.
