Which radars cover Foresta?
The closest NEXRAD Doppler radar is KHNX (San Joaquin Valley, CA), about 96 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 Foresta | View |
|---|---|---|---|
| KHNX San Joaquin Valley, CA | 96 mi south | 9,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDAX Sacramento, CA | 119 mi west-northwest | 12,500 ft | Limited — the beam overshoots the lowest part of storms |
| KMUX San Francisco, CA | 124 mi west-southwest | 13,400 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.
