Which radars cover Reston?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 8 miles west-northwest. 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 Reston | View |
|---|---|---|---|
| KLWX Sterling, MD | 8 mi west-northwest | 400 ft | Excellent — the lowest scan sees close to the ground |
