Sherburne County Multi -Hazard Mitigation Plan, 2020 <br />abnormally dry but not yet in drought. Abnormally dry conditions are indicative of the meteorological <br />circumstances that precede drought onset and those that are coming out of drought. Do is often <br />considered a bellwether of drought but it is also an accurate warning sign that crop growth may be <br />slowed and wildland fire risk may be elevated. Table 26 displays these drought categories along with <br />the potential impacts at each level. <br />Table 26.

Many of <br />these products are referred to as drought indices. These indices each serve a specific purpose. There are <br />indices that are designed for measuring short-term drought, and there are indices that are built to <br />reflect long-term drought. Similarly, other indices are useful for sector specific areas such as water <br />resources or agriculture. <br />Page176 <br />
