A rainfall warning's posted for Metro Vancouver and officials in Langley are dealing with the aftermath of a mud slide.

Langley Township operations manager Terry Veer says the slide's about 100 metres long and twelve inches thick, and has forced the closure of 264th street between 72nd and 84th avenues.

"It's not a really, really steep are but there is a higher area above the roadway... which has obviously given way."
 
One home has been evacuated.

"The mud actually slid down the driveway and damaged the garage door and went into the house."

Clean-up has yet to begin.

Officials are waiting for results of a slope-stability assessment.
