What it means for your home
These events show the pattern: king tides and storm remnants push water over seawalls and into low-lying coastal homes, and storm drains back up when tides are high. If water reaches your home, the first hour matters — make it safe, photograph, get things up, treat it as Category 3, start drying within 24-48 hours, and call your insurer and a licensed crew. See our Mission Beach tide flooding guide for the full checklist.
