You've got it, my friend. Where are they?
One is in Castaic. I5 is closed both ways (fire jumped the I5 freeway!) and the fire is getting nearer to her home. She also has a home in Frazier Park but no way to easily get there due to I5 and some indirect roads being blocked.
The other sister was evacuated from Big Bear yesterday, and went to her other home in the Mentone area. Now that area is on evacuation notice (not mandatory).
