Which radars cover Bayou Blue?
The closest NEXRAD Doppler radar is KHDC (Hammond, LA), about 63 miles north-northeast. 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 Bayou Blue | View |
|---|---|---|---|
| KHDC Hammond, LA | 63 mi north-northeast | 4,900 ft | Good — most storms and steady rain or snow show clearly |

| KLCH Lake Charles, LA | 156 mi west-northwest | 19,400 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.
