Is rain enough to put out large fires?

Mainly talking about huge fires such as what is happening in the west coast.

I know it seems like a dumb question, but when we put smaller fires out we usually dump a whole bucket of water on it. These forest fires are miles big and have a lot of things that are igniting it (like leaves and twigs) and rain doesn’t come down in big sheets like throwing a bucket of water out would do, rain is just droplets.

Would it take a huge thunderstorm? How long would it have to last?
