Which radars cover Stock Island?
The closest NEXRAD Doppler radar is KBYX (Key West, FL), about 3 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 Stock Island | View |
|---|---|---|---|
| KBYX Key West, FL | 3 mi northeast | 200 ft | Excellent — the lowest scan sees close to the ground |
| KAMX Miami, FL | 110 mi northeast | 11,100 ft | Limited — the beam overshoots the lowest part of storms |
| KTBW Tampa, FL | 221 mi north | 34,600 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.
