Which radars cover New Castle?
The closest NEXRAD Doppler radar is KDOX (Dover AFB, DE), about 59 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 New Castle | View |
|---|---|---|---|
| KDOX Dover AFB, DE | 59 mi south | 4,400 ft | Good — most storms and steady rain or snow show clearly |
| KDIX Philadelphia, NJ | 64 mi east-northeast | 5,000 ft | Good — most storms and steady rain or snow show clearly |
| KLWX Sterling, MD | 113 mi west-southwest | 11,600 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.
