REDDING (AP) — Containment of three big wildfires in Northern California has increased but potential for a new round of winds this week was a concern, authorities said Monday.

Containment of the 46-square-mile (119-square-kilometer) Lava Fire at the foot of volcanic Mount Shasta jumped to 70% after minimal overnight activity, Shasta-Trinity National Forest said. Remaining evacuation orders were downgraded to warnings.

To the northeast, the nearly 16.5-square-mile (42.7-square-kilometer) Tennant Fire rose to 51%, with evacuation orders and warnings continuing for nearby areas.

“The map’s looking fantastic this morning,” incident commander Jim Harris told a briefing.

Firefighters were cautioned that weather would be even drier and wind gusts could hit up to 25 mph (40.2 kph) by Tuesday and they needed to make sure the fire did not jump out of the perimeter.

In Southern California, a fire that erupted Sunday in mountainous northern Los Angeles County near Gorman remained at 1.5 square miles (3.8 square kilometers) with 10% containment.
