down here we have a pretty descriptive saying:
"run from the water"...storm surge and fresh water flooding kills
"hide from the wind".... evacuate, board up, or hunker down as your emergency plan dictates... keep a radio tuned for tornadoes that spin off
the rest is enduring the aftermath until normal returns...
lessons learned come a few at a time...if you have lived in an area for a while, try to pass on some of the lessons learned to others, especially new residents...
the internet allows you to reach out to a wider audience with your knowledge, and in return, learn from others..
these after action reports and lessons learned forums are a great source of information...
