Which radars cover Nanakuli?
The closest NEXRAD Doppler radar is PHMO (Molokai, HI), about 66 miles east-southeast. 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 Nanakuli | View |
|---|---|---|---|
| PHMO Molokai, HI | 66 mi east-southeast | 5,200 ft | Good — most storms and steady rain or snow show clearly |
| PHKI Kauai, HI | 96 mi west-northwest | 9,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| PHKM Kohala, HI | 177 mi east-southeast | 23,900 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.
