Metro Vancouver has raised the fire danger rating to extreme in all of its regional parks and greenways, and is asking the public to exercise caution when visiting these areas.After weeks of unrelenting heat and no precipitation, regional green spaces are tinder dry and extremely sensitive to sparks and fire. Warm, sunny and dry conditions are expected to continue through the week and long weekend, with forecasted temperatures in the mid to high 20s and no significant rainfall predicted for the next week. All regional parks and greenways, along with the Lower Seymour Conservation Reserve, remain open to the public at this time, but full or partial closures could be implemented in coordination with local fire authorities.During all times under extreme fire danger rating, Metro Vancouver will increase patrols and step up enforcement to protect natural areas in regional parks and greenways from the threat of wildfires. Those found engaging in high-risk, prohibited activities could be subject to fines ranging from $500 to $10,000.
