Which radars cover Bayou Vista?
The closest NEXRAD Doppler radar is KHDC (Hammond, LA), about 77 miles 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 Vista | View |
|---|---|---|---|
| KHDC Hammond, LA | 77 mi northeast | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLIX New Orleans, LA | 97 mi east-northeast | 9,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLCH Lake Charles, LA | 121 mi west-northwest | 12,800 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.
