“Even a moderate rainstorm from years past may have the impact of a major rain event following a wildfire,” MySafe:LA Executive Director noted during a recent L.A. area Neighborhood Council presentation. “That means that water will flow easily and if you can look up from where you’re standing and there’s a burn area, you’re at risk."
In burned areas, the soil chemistry is changed to such an extent that it becomes much more water-repellant. The roots and vegetation that typically absorbed rainfall have been burned away, and rainwater then runs straight downhill, often carrying whatever ash and debris is left on the surface with it. “To protect your home and family, learn about community resilience, and be prepared for winter rains,” Barrett said.
