The three legs of the fire triangle are fuel, oxygen, and heat. Being wet does not change the fact that wood is still fuel. If the thing is completely submerged, then it can displace the oxygen, but there’s no where near enough rain to do that. So that leaves heat, and water is very good at cooling things down. Wood burns at about 570⁰F (300⁰ C) so if we can keep the wood below that, it can’t burn.

Lightning strikes are about 50,000⁰F (27,700⁰C). That’s not a guarantee because lightning happens so fast, there might not be enough time for the heat to spread, but you get the idea why it’s still plausible that every once in a while, it can happen. Plus, the heat will basically instantly vaporize any nearby water.
