Which radars cover Emmaus?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 70 miles 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 Emmaus | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 70 mi southeast | 5,700 ft | Good — most storms and steady rain or snow show clearly |
| KBGM Binghamton, NY | 118 mi north-northwest | 12,400 ft | Limited — the beam overshoots the lowest part of storms |
| KDOX Dover AFB, DE | 118 mi south | 12,400 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.
