The most extreme level of a red flag fire warning, a "particularly dangerous situation," returned to parts of Los Angeles and Ventura counties Wednesday morning, heightening concerns about the potential for new fires to start.

Wind gusts of 50 to 70 mph in the mountains and 30 to 50 mph on the coasts and valleys are forecast for Los Angeles and Ventura counties on Wednesday. Residents exhausted by days of fire face red flag warnings with the rare "particularly dangerous situation" designation issued for those counties through Wednesday afternoon.
