Los Angeles County Fire Department and Angeles National Forest Service personnel are battling a fast-moving brush fire that started near Castaic Lake shortly after 10:40 a.m. Wednesday and quickly prompted evacuation orders for the lake and large swaths of Castaic.  The blaze, being called the Hughes Fire, spread quickly along both sides of Lake Hughes Road to the northeast of the lake, and radio dispatch traffic shortly after 11 a.m. indicated spot fires were popping up near the Ridge Route, approaching Interstate 5, prompting evacuations of residences, businesses and schools in the Castaic area.  “It is continuing to grow,” Deputy Robert Jensen of the Santa Clarita Valley Sheriff’s Station, said Wednesday afternoon around 1:30 p.m., adding that as of that time there were 20,000 residents in areas under evacuation order, with another 16,000 under evacuation warning. There were more than 6,000 structures threatened and 3,500 more were being considered for evacuation, a figure expected to grow, Jensen said Wednesday afternoon.  He said no structures had been lost as of 1:30 p.m.  As of 1:30 p.m., North Lake Hills Elementary had been evacuated and reunified at Valencia High School, as had Castaic elementary and middle schools, he added.   A temporary shelter-reunification center has been set up at both Valencia High School and The Cube, the city-run ice rink that’s across the street from the high school. Those places are being used until a more permanent location can be established, he added.  The Angeles National Forest posted on X at 1:33 p.m. that the fire had grown to 5,054 acres with 0% containment after it was previously listed at 3,004 acres about an hour before.  A temporary evacuation point has been set up at Hart High School, located at 24825 Newhall Avenue, according to the ANF.  At 2:13 p.m., ANF officials posted an updated evacuation order for the neighborhoods of Reyes Adobe, Francisquito, Tesoro Del Valle, Bitter Canyon, Sterling Lane, Sterling, Biscailuz and Charlie Canyon.   The Hughes Fire erupted northeast of Castaic Lake and quickly burned southwest, prompting evacuations in Castaic Lake. Habeba Mostafa/The Signal Castaic Sports Complex and Paradise Ranch Mobile Home Park were placed under evacuation order as of 11:20 a.m.  North Lake Hills Elementary was also being evacuated just after 11:30 a.m., according to Charmin Ortega, executive assistant to the superintendent of the Castaic Union School District.  Castaic High School, Castaic Middle School and Castaic Elementary School were all listed as being under evacuation orders as of 11:40 a.m.  Castaic Middle and elementary school students were being evacuated to the Ralph’s parking lost at Hasley Canyon Road, while North Lake students were being evacuated to the Castaic Sports Complex, according to the CHP Newhall-area office. “As many of you may know, a vegetation fire is currently burning on the east side of Castaic Lake,” reads an alert sent by the William S. Hart Union High School District to Castaic High families. “We have been reassured by our law enforcement and fire partners that the school is currently not in any danger. Out of an abundance of caution, and as a result of poor air conditions, we will be ceasing all school activities for the day immediately. Students will be dismissed to leave at 11:40 a.m.  “For any students who are not able to be picked up, we have buses coming at this time to transport students to West Ranch High School. We will notify all families once those buses leave so you will know where to pick your child up.”  In a message sent to the entire Hart district community just after 12:30 p.m., families were alerted that no other schools were in warning areas but that officials were “closely monitoring the situation and air quality” and updates will be provided as necessary.  Valencia High and Rio Norte Junior High were eventually put under an evacuation warning, but after dismissal time, according to an alert sent to families and staff.  “Both schools have reached dismissal time and all after school activities are canceled. We will provide further information before the start of school tomorrow,” the alert reads.  Smoke could be seen Wednesday afternoon approaching homes in the north of Santa Clarita.
