Forecaster Gerald Cheng of Environment Canada says we'll see more smoke and haze from forest fires, especially in hot weather.

"Unfortunately, the fires are still burning, and as long as the source is still there -- combined with a westerly flow -- the conditions are still there," Cheng noted.

However, the amount of smoke may vary, according to wind and temperature. In general, the forecaster says we can expect the haze to get worse as the days get warmer in the afternoon.

"There's more convection going on, just in general, and it mixes down some of that air to the surface. That becomes a problem," Cheng added.

There are close to 600 fires burning in B.C., in addition to about 60 burning in the northwest region of Ontario.
