Which radars cover Port Sulphur?
The closest NEXRAD Doppler radar is KLIX (New Orleans, LA), about 58 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 Port Sulphur | View |
|---|---|---|---|
| KLIX New Orleans, LA | 58 mi north | 4,300 ft | Good — most storms and steady rain or snow show clearly |
| KHDC Hammond, LA | 81 mi north-northwest | 7,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMOB Mobile, AL | 120 mi northeast | 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.
