From 2025-11-11 through 2026-11-11, National Weather Service severe reports for Loudoun County include this headline: 66 mph winds recorded in Loudoun County. That is a county record. It does not mean every home in these ZIP codes experienced that weather. A county wind headline is not a deck inspection. Soft boards, loose ledgers, and wobbly rails are what we look at on site.
