How to spell BULDEROUS correctly?

If you meant "boisterous", then make sure to use that word instead. However, if you're trying to describe something that's loud and rumbling, then "thunderous" might be more appropriate. Alternatively, you could try using "rumbustious" or "blustery" to capture the same meaning.
