Thunderstorm Wind — Alexandria (c), Virginia

2023-07-29 · near Alexandria, Alexandria (c), Virginia

Event narrative

Hundreds of large trees, branches, and wires blew down in the City of Alexandria, especially in Old Town North, Del Ray, Rosemont, and North Ridge. Many fell onto cars and houses.

Wider weather episode

A strong cold front intersected a very hot, humid, and unstable airmass across the Mid-Atlantic shortly after peak heating. Aided by dynamics and moderately strong shear from an approaching upper-level trough, the front spawned bands of thunderstorms that produced considerable wind damage particularly in the I-95 corridor. Some areas saw the worst thunderstorm-driven wind speeds and damage since the derecho in June 2012, though the area affected by the highest magnitude of winds was not nearly as large.
