From 2025-11-11 through 2026-11-11, National Weather Service severe reports for Harford County include this headline: 63 mph winds recorded in Harford County. That is a county record. It does not mean every home in these ZIP codes experienced that weather. Wind is not how we decide a gutter is failing. Overflow, sagging runs, and water at the foundation are.
