What is precipitation rate measured in?
Both numbers relate directly to a chance of receiving at least that amount of rain. The first number (5 mm in this example) represents a 75% chance of at least that amount of rain occurring. The second number (10mm in this example) represents a 25% chance of at least that amount of rain occurring.
