Hazards that include adverse localised weather, which are a source of major causes of crop loss, such as hail, drought, etc., can have various effects on crops. These effects can range from flood/excess precipitation or moisture, stress from heat, drought (including drought-related effects such as pests damage), frost/freeze, hail, and winterkill. The impact on crop can be extraordinary depending on growth phase of the plant being cultivated, the growing season, duration, frequency and intensity of the adverse weather condition(s) in question. For example, pest populations can be allowed to multiply as a result of prolonged drought during a warmer-than-average winter, which in turn can lead to large scale decimation of crops in the coming season. Or a single prolonged intense period heat can amount to more crop loss than several shorter periods
