SCU LIGHTNING COMPLEX INCIDENT UPDATE 9/3/20 7AM
The SCU Lightning Complex started on August 16th with multiple fires within the complex. These fires have since merged into one major fire which is broken into two branches, Branch I and Branch II. Minimal activity overnight. Heavy materials continue to burn down and leave hot deep-seated ash pits. Continued dry conditions above 2,000'. The inversion layer setup around 2000 feet overnight, with warm and dry conditions above it. Temperatures this morning were generally in the 70s above the inversion, while temperatures dipped into the 60s below the inversion. Humidity recovery was in the 25-35% range for much of the night, although localized areas saw humidity to 20% during the early morning hours. Winds were generally light, and terrain driven. Another round of hot and dry conditions is forecast for today. High temperatures will be in the 80s and 90s. Afternoon humidity will be near 40% over western portions of the fire, to near 20% over eastern portions. Winds will generally be light and from the northwest. High pressure will bring a warming and drying trend that will last through Labor Day Weekend, and an Excessive Heat Watch is in effect from Saturday through Monday. Otherwise, a cooling trend is forecast for early next week, with the potential for an uptick in wind speeds
