Alabama Flash Drought

UPDATE: Fire Alert Issued in Alabama (more info below)

What is a “Flash” Drought?

A flash drought is the rapid onset of drought. While conventional drought is mainly driven by a lack of precipitation, flash drought is often caused by a combination of abnormally high temperatures, winds, and/or incoming radiation that leads to abnormally high evapotranspiration rates (read more).  After enduring one of the hottest and driest Septembers on record, Alabama and the vast majority of the Southeast are currently in flash drought conditions.

Flash droughts can have extreme agricultural impacts, particularly due to their characteristic rapid onset that increases the difficulty of forecasting their development.  A study called, Flash Drought Characteristics Based on U.S. Drought Monitor” was conducted by NOAA, the National Weather Service (NWS), and the National Centers for Environmental Prediction (NCEP) Climate Prediction Center to investigate how to better predict flash drought development.

U.S. Drought Monitor

The USDM was released on October 3, 2019.

The United States Drought Monitor (USDM) is a map released weekly, detailing the areas of the U.S. that are in drought.  The map has 5 classifications:

  • DO (Abnormally Dry) – areas that may be going into or are coming out of drought
  • D1 (Moderate Drought)
  • D2 (Severe Drought)
  • D3 (Extreme Drought)
  • D4 (Exceptional Drought)
  • Read more about USDM classifications.
