Which radars cover Petersburg?
The closest NEXRAD Doppler radar is PACG (Biorka Island, AK), about 100 miles west. 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 Petersburg | View |
|---|---|---|---|
| PACG Biorka Island, AK | 100 mi west | 9,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| PAIH Middleton Island, AK | 524 mi west-northwest | 161,600 ft | Limited — the beam overshoots the lowest part of storms |
| PAHG Kenai, AK | 717 mi west-northwest | 290,000 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.
