Air quality advisory remains in effect for Metro Vancouver and Fraser Valley

Jul 31 2018, 3:27 pm

An air quality advisory that was issued over the weekend for parts of Metro Vancouver and the Fraser Valley still remains in effect.

The following areas are affected:

  • Metro Vancovuer NE
  • Metro Vancouver SE

Environment Canada cites one of the reasons as high concentrations of ground-level ozone that are expected to persist today.

The highest levels of ozone are generally observed between the mid-afternoon and early evening; people are recommended to avoid strenuous outdoor activities, particularly during when ozone levels are the highest.

The advisory has also been expanded to include fine particulate matter, also known as PM2.5, an airborne solid or liquid droplet with a diameter of 2.5 micrometres or less. Fine particulate matter can also easily enter an indoor setting due to its small size.

Levels of fine particulate matter may filter into parts of Metro Vancouver and the Fraser Valley due to wildfire smoke from outside the region as well as local sources.

Infants, the elderly, or those who have an underlying medical condition such as lung disease, heart disease, diabetes, or asthma are especially at risk.

Metro Vancouver Heat Wave Continues

Vancouver’s heat wave, which began early last week, is still going strong.

Temperatures pushing 30° are expected inland, with slightly lower temperatures closer to water.

According to Government Canada, this period of hot weather is “likely to end tonight as cooler marine air pushes onto the coast.”

A weekly weather forecast also shows a dramatic drop in temperature on Wednesday, as well as some showers from Thursday into the weekend.
