Sources tell TMZ Elin and the kids arrived at the home yesterday afternoon with a security team in tow -- and this morning, the entire crew was still there.
We're told the move could be permanent -- after Elin arrived at the home yesterday, a large truck showed up and workers began moving stuff into the house.
As for Tiger -- we're told he's been at the range all morning working on his game ... paying special attention to his putts.
