How to read this

Wet bulb is temperature adjusted for humidity. Guns start around −2° on this scale, not on the ordinary thermometer.

Grey: too warm. Darker blue: colder and better for guns. Percent of the gun’s top water flow, our estimate.

Yes means at least 6 hours in a row at about 30 % or more within three days. Our rule of thumb; the operator decides.

Only the operator and the webcam show whether guns are really running.
