SHELTON, Wash. -- One person was killed and three other people were injured when the car they were in went off the road and crashed into a tree early Tuesday.

Mason County sheriff's Detective William Adam said the crash happened just after midnight in the 400 block of East Mikkelsen Road north of Shelton.

A woman who was in the car died at the scene and a man was airlifted to Harborview Medical Center in Seattle. Two other men were also injured.

Deputies are still investigating the crash and it was not clear what caused the driver to run off the road.

The name of the woman who was killed has not been released.

Happy Mother's Day! 

We are in for some wonderful weather for getting outside. 

Plan on sunny skies today with highs in the mid-70s to low-80s in many spots.  The warmest areas will be in the south Sound.

The strong ridge of high pressure will stay locked in for Monday with highs rising a few degrees.

Even Tuesday is looking mostly sunny with a few high clouds toward the end of the day.  It isn't until late Wednesday that the ridge breaks down enough to allow a stronger onshore flow to bring us more clouds and cooler temps.  By Thursday morning we could even have some areas of mist.

A ground search is underway for man who hasn't returned after leaving for day hike in Olympic National Park on Monday.

On Wednesday officials from Olympic National reported David Snidder, 55, of Union, was overdue from a planned day hike on Irely Lake Loop Trail.

Snidder's car was found at the North Fork Campground the same day when an initial “hasty” search began, according to a park news release.

Clues, believed to be left by Snidder, were found by a ground search team on Thursday afternoon.

Friday's search is focused on the Irely Lake and Reflection Lake area and includes 16 ground searchers, including 8 technical rescue team members from Olympic Mountain Rescue, along with a German Shepherd Search Dog with its handler from Pierce County and a helicopter.

Snidder is described as a capable hiker with previous experience in mountainous and snowy terrain. Officials believe he is traveling with a day pack and basic essentials.
