Highway 18 heading into the mountains was closed for hours before reopening at 4 p.m. Firefighters are contending with 20 to 30 mph winds with gusts up to 60 mph, according to the National Weather Service. A high wind warning for San Bernardino County is in place until about noon, when winds are expected to subside. A red flag warning has also been issued for the area until 6 p.m. About 500 firefighters were on the scene of the fire, San Bernardino National Forest Department Chief Scott Howes said earlier in the day Thursday. A full complement of firefighting aircraft were also deployed to the incident, he said. All San Bernardino Unified School District schools are still expected to be open, officials posted about 4:45 a.m. About 10 a.m., fire officials tweeted that they had determined where the blaze began, but the cause remains under investigation. “There are NO power lines near the area of origin,” officials said in the tweet. Officials are working to determine a cause of the fire. Another brush fire burned in the area last week. The Old Water fire scorched more than 100 acres after starting near Old Waterman Canyon Road and Highway 18 on Oct. 24.
