Humidity levels will drop to around 5 percent with poor recovery overnight.
High temperatures Tuesday will be 75 to 80 degrees near the coast and inland, 75 to 80 degrees in the western valleys, 65 to 70 near the foothills and 53 to 62 in the mountains.
Vegetation is very dry and fires will grow rapidly, burn intensely and be difficult to control upon ignition, according to the Santa Ana Wildfire Threat Index.
