Family in Waialua red flood zone not evacuating

My ex has our kids in Waialua. They are in a red zone right across from Otake camp and he is refusing to evacuate. Is there anything I can do to at least get the kids to safety? There are 4 young children in that house and his girlfriend is pregnant. He will not respond to my request to pick up the kids or offering up my house to his family.

A few people have asked so here’s an UPDATE:

The roads are open but I heard electricity won’t be back on until Monday. Cell service is up, but spotty.

The community came together and there are a lot of groups helping out with cleanup, supply distribution, food, etc.

Their dad says the kids are safe but won’t let me talk to them or pick them up a day early (per custody schedule) to get them out of the disaster zone. He got mad at me for offering.

Rescue workers had video of their street/neighborhood and it’s covered in mud and debris. I heard they’re being advised to boil all tap water until further notice.

Just got back from dropping off water to a relief station. Unfortunately I don’t have the right gear to help with the debris cleanup. Didn’t get to see the kids when I was up there.
