Tree limbs that break off in high winds were often incorrectly pruned, plus how much defensible space is enough for fire safety?

The Santa Ana winds fanning wildfires that have killed at least 25 people in Southern California and destroyed more than 10,000 houses, businesses and other structures in Greater Los Angeles are flaring up again.

Now, Santa Ana winds are expected to sweep through the area early next week, accompanied by low humidity, meaning more potentially dangerous fire conditions. Here's what to expect over the weekend and into next week.

National Weather Service offices across Southern California are warning residents of an increase in weather conditions that are conducive to rapid fire growth. Meteorologists are most concerned about conditions from Monday afternoon through Wednesday morning when winds will be at their peak and relative humidity will be low.

Yet another Santa Ana wind event is set to descend upon the Los Angeles area to begin the week, leading weather officials to issue a Fire Weather Watch.  According to NWS, “moderate to locally
