Wetting periods start with rainfall (at least 0.01 inch) and continue
until the start of at least eight hours without moisture (rainfall, leaf wetness, high relative humidity).
Wetting periods are classified as "ongoing" until eight consecutive dry hours have passed.
After that, the official end of the wetting period is recorded (the start of the 8 hour dry period).
