May 15, 2018
Affected Communities: 
Electoral Area C, Village of Pemberton

Note from the SLRD: The High Streamflow Advisory below was issued by the BC River Forecast Centre. The public is reminded to exercise caution around rivers and streams due to quickly flowing water and potentially unstable riverbanks.


High Streamflow Advisory issued for the Lillooet River

Extreme temperatures have persisted since the weekend, with Pemberton and Central Coast areas experiencing record temperatures on Sunday. This has led to rapid snowmelt, and increasing flows in rivers draining from areas of the Coast Mountains.

Weather is expected to continue to be warm through Wednesday, with the chance of showers developing on Thursday into Friday and Saturday. On-going rises in river levels are expected into the long weekend.

The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.


Levels of Warnings/Advisories:

  • High Streamflow Advisory: River levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible.
  • Flood Watch: River levels are rising and will approach or may exceed bankfull. Flooding of areas adjacent to affected rivers may occur.
  • Flood Warning: River levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result.
