That registers on my scale as "Quite a lot". - Quite a lot of food defrosting right now.
We're still recovering from a lightning strike here that took out 20+ routers and connected equipment last week and the lines are still not back in some areas as they have had to replace quite a major chunk of the network including replacing a street cabinet. Has taken out quite a lot of equipment that was on LAN cable connected to routers as the strike jumped the line protection. Most routers aren't earthed at all - and therefore just pass the current onto the connected devices that are.
I always remember getting thunderstorms in the Summer but they may be getting more severe. We had flooding here about 8 years ago and we narrowly escaped wet feet by a mere 1/4". I am now taking steps to be better protected from the weather which puts me into the realm of "Prepper".
I have changed my garden design so it now has 8" raised beds around the outside of it. This forms an effective embankment to prevent flooding from that side. I also have 20+ potato planters - fabric bags with two handles containing soil, which can be deployed as sandbags if needed. I also have a pond for water, but with that is a water pump that can be relocated. I have added a land drain for surface water, but is a question of what happens when the drain system is overloaded. Last time water was still going down it and not coming up.
We have back-up cooking systems - camping gas, disposable BBQ charcoal, a woodpile and a crate of hexy stoves, as well as enough noodles and tinned food to last a while.
I have repaired 240v inverters, from smalI 300W up to a 1200W one, and enough batteries to last a few days. Also an old Honda suitcase generator with 4 cans of fuel for it. If all else fails I have a fully fitted campervan that we can live in.
I am now fitting surge protection to the phone line and a battery backup for the router. Electrical equipment is getting surge protected multiplugs (but are almost useless) but will be upgrading or building my own when I can. I am learning more as I go along.
I think the main thing to think about is reducing the effects of these things when they happen. To me flooding is the major issue, after that a long time without power that will waste food in the freezer, and beyond that the horror of not having internet.

I don't think the kids would survive that.
