The categories of drought are defined as follows:
Abnormally Dry (D0) - Going into drought: short-term dryness slowing planting, growth
of crops or pastures; fire risk above average. Coming out of drought: some lingering water deficits;
pastures or crops not fully recovered.
Moderate Drought (D1) - Some damage to crops,
pastures; fire risk high; streams, reservoirs, or wells low, some water shortages developing or
imminent, voluntary water use restrictions requested.
Severe Drought (D2) - Crop or pasture losses
likely; fire risk very high; water shortages common; water restrictions imposed.
Extreme Drought (D3) - Major crop/pasture
losses; extreme fire danger; widespread water shortages or restrictions.
Exceptional Drought (D4) - Exceptional and
widespread crop/pasture losses; exceptional fire risk; shortages of water in reservoirs, streams,
and wells, creating water emergencies.
