Droughts are normal climate features. They can occur almost anywhere.
There are three commonly described types of drought.
- Meteorological drought is usually measured by how far from normal precipitation has been over a period of time.
- Agricultural drought occurs when soil moisture is insufficient to meet crops’ needs to produce an average crop. It may occur in times of average precipitation depending on soil types.
- Hydrological drought refers to deficiencies in surface and subsurface water supplies.
2007 appears to be a record drought year for Alabama. Up-to-date information about drought conditions can be found on the U.S. Drought Monitor Web site
NOAA's National Weather Service in Birmingham describes the drought impact on agriculture, hydrology, and its impact on society. The site also reviews the increased fire danger.
