Which radars cover Nassau Bay?
The closest NEXRAD Doppler radar is KHGX (Houston, TX), about 5 miles south. 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 Nassau Bay | View |
|---|---|---|---|
| KHGX Houston, TX | 5 mi south | 200 ft | Excellent — the lowest scan sees close to the ground |
| KLCH Lake Charles, LA | 119 mi east-northeast | 12,600 ft | Limited — the beam overshoots the lowest part of storms |
| KGRK Central Texas, TX | 160 mi west-northwest | 20,100 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.
