Which radars cover San Castle?
The closest NEXRAD Doppler radar is KAMX (Miami, FL), about 69 miles south-southwest. 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 San Castle | View |
|---|---|---|---|
| KAMX Miami, FL | 69 mi south-southwest | 5,600 ft | Good — most storms and steady rain or snow show clearly |
| KMLB Melbourne, FL | 113 mi north-northwest | 11,600 ft | Limited — the beam overshoots the lowest part of storms |
| KTBW Tampa, FL | 164 mi west-northwest | 21,000 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.
