Yes, I have been caught in drains when it started raining, I did check the weather beforehand, radar pattern too but.. it does happen. I was very surprised by the force of the water. Here are the claimed odds of death at varying tsunami depths.
Just don't risk it.
100cm – 100% chance of death
“You cannot stand. You’ll be hit by floating debris. The probability of death is high.”
70cm – 71.1% chance of death
“The force of water above the knees gets stronger. Even a healthy adult would get swept away.”
50cm – 4.8% chance of death
“Cars and containers float. You can remain standing if you hang onto something.”
30cm – 0.01% chance of death
“A healthy adult can manage to stand. It’s difficult to walk.”
