2000+ Latency every 10-12 minutes after recent storms

We recently had some storms come through last week and knocked down a lot of trees and power. Once the outages were resolved, I started having intermittent latency issues. The issue occurs roughly every 10-12 minutes where I will go from 10-20ms to 2000+ms. This is causing issues with gaming / streaming / etc. The latency last about 5-10 seconds then clears. All equipment has been rebooted/bypassed/isolated. I can ping my modem gateway IP and the response times are normal (1ms). It only occurs when I ping anything outside of my network on the Xfinity network or beyond. This happens using a wired connection and wifi connection, it does not matter. I've used multiple computers as well.

This is a sample of it occurring:
