Supporting Conditions
Southern California has seen record temperatures over the past week, with many towns and cities breaking all-time heat records. In some locations, temperatures were 15 degrees higher than normal for the time of year. This, combined with slightly drier conditions than normal and gusty onshore winds, rapidly dried out fuels.
Forecast
- Temperatures are dropping from the record heat, though they expect to remain in the 80s and 90s throughout the interior. Relative humidity is expected to increase slightly in the affected areas, though minimums of 5 to 15% will be common.
- Red Flag Warnings remain in effect for the interior mountains and foothills of Los Angeles County. Gusty winds are expected, with sustained winds of 15 to 25 mph and gusts up to 40 mph. These conditions will persist into Wednesday evening. Lighter winds are expected by Thursday.
