What is ironic about chiefs being both deaf and mouth

First, you have to find the main idea (Which is "Thundersnow is dangerous")

Then, you have to find the supporting details, which is what the question is asking for

I believe these are the details:

-When it comes to lightning risk, a thunderstorm of snow, or thundersnow, is no different from a thunderstorm of rain.

-Thunder signifies the presence of lightning, so even if you don't see any lightning flashes, it's crucial to seek safe shelter in order to avoid being struck.

-In addition, thundersnow often involves heavy snowfall and enormous ice pellets, creating even more safety risks

I hope this helps and is correct! Good luck!
