Lost of internet connection

The past 3 or 4 storm in my area have caused an internet outage. What I don’t understand is the delay in the disruption? During the storms, my internet and connection maintain and are fine. But it seems the day after the storms is when I lose my connection. Why is this? I work from home so having a reliable and stable connection is importance. I completely understand this happening sometimes. But now it just seems anytime there is a storm in the forecast, I can expect an outage.
