HILDALE, Utah (AP) – The latest on the deadly flash flooding to hit the Utah-Arizona border region (all times local):

10:31 a.m.

Authorities have warned residents in a small polygamous town on the Utah-Arizona border to boil their drinking water following deadly flash flooding.

The local water department issued the advisory as a precaution Wednesday after floods tore through the sister cities of Hildale, Utah, and Colorado City, Arizona, sweeping away two vehicles Monday and killing at least 12 people. One boy is still missing.

Washington County Emergency Services in Utah said no contamination has been found, pending water sample testing, but that boiling water for one minute would guarantee it’s safe to drink.
