Last year's Santa Ana winds felled 300 trees at the LA Arboretum and damaged many more.
Southern California steels itself for yet another round of the gusty Santa Ana winds, due to roll in this weekend.
The National Weather Service says surface high pressure will build Saturday night and early Sunday morning, causing a "moderate to strong wind event" as dry air squeezes through mountain passes and canyons into Southern California.
Forecasters posted a fire weather watch from Saturday night through Sunday afternoon due to the combination of gusty offshore winds, low humidity and dry vegetation.
Southern California Edison warned of the wind's potential effects.

Los Angeles' eastern suburbs are still recovering from a string of winds last November that caused massive damage and weeks of lost power.
The northeast winds will rapidly lower humidity levels anywhere from 10 to 15 percent, with single digit humidity in the mountains.
