The data presented in this drought report are preliminary. Ranks, anomalies, and percent areas may change as more complete data are received and processed.
Several climate indicators are used to monitor drought in the United States. These indicators include:
the Palmer Z Index, Palmer Drought Severity Index, and Palmer Hydrological Drought Index
the one-month, two-month, three-month, six-month, nine-month, 12-month, and 24-month Standardized Precipitation Index
maps showing the percent of normal precipitation for airport stations for the current month and year-to-date
the statewide precipitation ranks for current month (short-term) and 3-months, 6-months, and 12 months (longer-term)
the short-term surface wetness anomaly map computed by the National Climatic Data Center from the Special Sensor Microwave Imager (SSMI), a polar orbiting satellite with global coverage

The surface wetness anomaly map shows areas of above and below average liquid precipitation wetness. During the winter months, it should be used in conjunction with the snow cover anomaly map.

The snow cover anomaly map shows areas of above and below average frozen precipitation "wetness". An area with above-average snow cover may appear to have below-average liquid wetness.
