None to speak of.
We see waves lapping at the top of a large dam that then breaks open, sending a massive flood across the land toward Evan's subdivision. Everyone there panics and boards the ark that's then swept away by the floodwaters. The ark crashes through Evan's house, while the raging waters rip through others. Everyone onboard the ark then holds on as the floodwaters carry it toward Washington, DC, including over a tall waterfall. When they approach a stone bridge on the Potomac River, Evan asks for help and a huge wave lifts them above that and careens down the national mall until the ark crashes right on the doorstep of the U.S. Capitol. It's presumed many people would have been swept away by the floods (and wounded or killed), but that's never made clear one way or the other.
At least 1 incomplete, possible "s" word (although it could just as easily have been the start of the word "shoot" or any others that start with "sh"), 4 uses of "Oh my God" and 1 use each of "By God" and "God" as exclamations.1 use of "pissed."
About Evan's long hair, beard, and the way he's acting, Rita sarcastically asks, "What, are you shooting up Rogaine?"
While driving, Evan reacts adversely to two tarantulas crawling on him, and some snakes slithering along him.
