Which radars cover Kalaheo?
The closest NEXRAD Doppler radar is PHKI (Kauai, HI), about 3 miles 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 Kalaheo | View |
|---|---|---|---|
| PHKI Kauai, HI | 3 mi southwest | 200 ft | Excellent — the lowest scan sees close to the ground |
| PHMO Molokai, HI | 161 mi east-southeast | 20,300 ft | Limited — the beam overshoots the lowest part of storms |
| PHKM Kohala, HI | 272 mi east-southeast | 49,500 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.
