Hurricane season is here. What's your prep list look like?

June 1 through November 30. Most years we get lucky. The years we don't are why year-round residents take it seriously. I keep a permanent list: water, batteries, generator fuel, propane, important docs scanned and in the cloud, two filled prescriptions ahead. Insurance policy and contact numbers printed and in the car. What's on your list that's saved you? What did you learn the hard way? This is the thread to compare notes before the season gets going.
