| 2026-07-05 | 7:00 AM | 0.35 | NA | NA | NA | NA | | The speed and intensity of this storm took everyone in town management by surprise. Obviously the fireworks got cancelled. In the 10 minutes it took me to drive home, the winds picked up furiously and I felt I was in a movie. Debris was flying everywhere and I had to take evasive action multiple times. The climax was getting into my driveway, where a dead ash fell seconds before I got there, and blocked me completely. It shattered on impact and I was able to move it out while getting hit in the head with falling debris from other trees. Sorry for the dramatic post but this one was special. I should add that the entire neighborhood has lost power. |
