My humble opinion it's that you will not even have time to get our of the house like others said, unless you are in a fovrabtleble position like clos to an hill. I recall reading some stories of survivors of the Vajont dam disaster telling that thei heard a distant growl and seconds later the water came, some survived just because their house was 50 cm above the others. So basically little to no warning and you can't outrun water.
