Very good article in the Paper today about the heat, and the fire danger.

We have already had 4 days of Extreme Fire Danger… the most for June in at least the past 14 years.

Please, just because it will be a little cooler, relatively, on Friday and the weekend, be very very careful out in the bush and read the rest of this post.

On Tuesday 32 of the agency’s 39 weather stations went into crossover, a term used to describe temperatures climbing above the relative humidity, indicating hot, dry conditions.

That goes for my station as well. You can see the effect in this graph when the “Heat Index” (red line) is actually below the temperature because it is so dry.

Below is the Humidty today (Blue line)… went down to an incredible 14% at my station. It wouldn’t have been that low in the bush… but likely no more than 3 or 4% more out in the bush.

“Yesterday [Tuesday] was the biggest span with 30.7 C at 20% relative humidity,” MacPherson said. “That’s a huge span. When you get that kind of crossover our spidey senses start tingling. We’re looking at very easy ignition.”

I’m pretty sure it was worse today.

But this is the really dangerous news:

Long-term forecasts from Environment Canada are for higher-than-normal temperatures for the summer and below normal rainfall. While the Valley can expect a cooling trend towards the weekend, there’s no call for rain. Still, the changing temperatures and weather aren’t good for firefighters.

“We’re hearing the lightning word for Friday or Saturday with no rain attached,” MacPherson said.

Please, if you’re camping or doing *anything* with fire (smoking, or whatever) be SO careful.

The green that is still around can be very deceiving… all it takes is a little bed of pine needles or a scrap of paper.

  1. Yay! Its 5:45 and cool enough outside to turn off the A/C and enjoy the easterly breeze when I open the doors on the house!
