Red Flag Warnings for extreme fire weather are in effect for most of the forested and brush-covered lands in southern California. The pattern along the Colorado River is interesting, and indicates that the weather forecasters put some thought into this, rather than simply using state boundaries as has been done in some cases previously.
The weather forecasts vary from one location to another in southern California, but they generally call for strong northeast winds of 20 to 30 mph gusting at 50 to 60 mph, along with very low humidities. The Red Flag Warnings mostly begin late on Thursday and continue into Saturday.
The map was current as of 9:25 a.m. MT. Red Flag Warnings can change throughout the day as the dozens of National Weather Service offices around the country update and revise their forecasts. For the most current data, visit this NWS site.
