Since I am following the fire weather forecasts, I had to figure out a few cryptic references. Among them…
CWR is “Chance of Wetting Rain” — how likely it is that you’ll see more than about 0.1 inches of rain.
The “Haines Index” is used to indicate the potential for wildfire growth by measuring the stability and dryness of the air over a fire. Values range from 2 to 6. The smaller the number, the better.
LAL is “Lightning Activity Level.” It ranges from 1 to 6. See below for details but, again, the smaller the number the better when it comes to fire suppression.
