Flood Warnings and Advisories

High Streamflow Advisory – Lillooet River, Bella Coola River
ISSUED: 1230h May 15th, 2018

The River Forecast Centre is issuing a High Streamflow Advisory for:

  • Bella Coola River
  • 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.
