Great Drought , climatic interval of the Holocene Epoch that affected much of what is now the western United States and had a profound influence upon the plants, animals, and prehistoric Native American cultures of the region. The Holocene began about 11, years ago and continues to the present. The region affected by the Great Drought encompassed the area that extended from what is now Oregon to southern California and east to what is now eastern Texas; dendrochronology , or tree-ring studies, indicate that it began in ad and continued through Ancestral Pueblo Anasazi and Hohokam peoples were particularly affected by the Great Drought; their agricultural economies had by this time enabled them to form densely occupied communities.
After repeated years of crop failure, they were compelled to abandon their towns and disperse across the land. Parallel reductions in wild food sources affected nomadic peoples, and social disruptions are thought to have occurred as nomads and former farmers were placed in competition for the few resources that survived under very dry conditions. The Great Drought was but one of several major periods of drought that have affected the same region in the past three millennia.

Rainfall during July was below average for most of the southern half of Australia, although areas of eastern Victoria and coastal New South Wales had above average rainfall. Daytime temperatures during July were warmer than average for most of the country; the maximum temperature was the seventh-highest on record for July for Australia as a whole. Below average July rainfall has seen rainfall deficiencies increase for the period April—July over the south-western half of Western Australia, and to a lesser extent over the same area for the period since April Low pressure systems off the east coast of Australia brought periods of very heavy rain to the east coast at times during the month, resulting in a reduction of rainfall deficiencies in parts of eastern Victoria and south-east New South Wales at both timescales.
May—July rainfall has been below or very much below average over most of the southern half of Australia, except in Gippsland and eastern New South Wales where totals have been close to average.

The Sahel has long experienced a series of historic droughts, dating back to at least the 17th century. The Sahel region is a climate zone sandwiched between the Sudanian Savanna to the south and the Sahara desert to the north, across West and Central Africa. While the frequency of drought in the region is thought to have increased from the end of the 19th century, three long droughts have had dramatic environmental and societal effects upon the Sahel nations.

A wild card for this outlook is the increased potential for a continued active Atlantic hurricane season. This is due to the potential for the active phase of the Madden-Julian Oscillation MJO to shift into the Atlantic Ocean, temporally coinciding with the peak of the hurricane season in early September. Therefore, several synoptic-scale forcing mechanisms are considered in this forecast, in addition to the short-, medium-, and long-range model guidance and seasonal normals.
Much of the West is expected to remain in drought, with some additional development likely in the Southwest during the SON season, as warm and dry conditions are favored for much of the West. The exception is the Pacific Northwest, where above-normal precipitation and drought removal D1 and improvement D2 and worse are favored. In the Northern Plains and Midwest, drought removal D1 and improvement D2 and worse are favored due to decreasing evapotranspiration rates during the Fall and climatologically wider-spread synoptic events.
The Central and Southern Plains will be a wild card, due to the climatological positioning of the storm track coinciding spatially with increased odds for above-normal temperatures and below-normal precipitation during the valid period. Additionally, the potential for enhanced tropical activity further reduces forecast confidence for those areas.

National Geographic Emerging Explorer Alexandra Cousteau started the nonprofit Blue Legacy to raise awareness about water issues around the world. She believes water problems such as drought, storms, floods, and degraded water quality will be a crucial issue in this century. A drought is a period of time when an area or region experiences below-normal precipitation. The lack of adequate precipitation, either rain or snow, can cause reduced soil moisture or groundwater , diminished stream flow, crop damage, and a general water shortage.
Exploring the added value of a long-term multidisciplinary dataset in drought research – a drought catalogue for southwestern Germany dating.
With the western United States and northern Mexico suffering an ever-lengthening string of dry years starting in , scientists have been warning for some time that climate change may be pushing the region toward an extreme long-term drought worse than any in recorded history. A new study says the time has arrived: a megadrought as bad or worse than anything even from known prehistory is very likely in progress, and warming climate is playing a key role.
The study, based on modern weather observations, 1, years of tree-ring data and dozens of climate models, appears this week in the leading journal Science. We now have enough observations of current drought and tree-ring records of past drought to say that we’re on the same trajectory as the worst prehistoric droughts. Reliable modern observations date only to about , but tree rings have allowed scientists to infer yearly soil moisture for centuries before humans began influencing climate.
Among other things, previous research has tied catastrophic naturally driven droughts recorded in tree rings to upheavals among indigenous Medieval-era civilizations in the Southwest. The new study is the most up-to-date and comprehensive long-term analysis. It covers an area stretching across nine U. Using rings from many thousands of trees, the researchers charted dozens of droughts across the region, starting in AD.

Commercial and other non-domestic water users cannot: Use an outdoor hose or water blasting device when connected to the metropolitan supply network unless it is for health, safety, emergency or biosecurity reasons. Operate a car wash unless it uses recycled water.

ADRMP continues to provide a framework for a coordinated, pro-active approach to reduce the short- and long-term effects of drought and of climate change on Alberta farmers and ranchers. It will guide government agencies in assisting producers to more effectively reduce the impacts of drought before, during and after a drought event, and will help agricultural producers to be more prepared and less vulnerable to drought.

This page was updated on 22 Nov to include the disclaimer below. No other content in this article was affected. The purpose of this article is to bring that survey up to date with information to inclusive. While broadly summarising the material from the earlier article, the most recent widespread and severe drought in Australia, the drought of , is given a special mention.
Developments in the Australian Drought Watch Service, operated by the Bureau of Meteorology, and in the monitoring of variations in the climate that can lead to drought are also briefly described. However the term is relative because water availability, which depends on supply and demand, is affected by regional differences in both the climate and the activities of the water user.
To a large extent, users adapt to a perception of what is the normal supply for an area but there are other differences. A farmer, for example, is concerned with insufficient water during a season for crops, pastures and stock. A civil engineer in the same area may be more concerned with longer term aspects associated with the storage and managing of water in a reservoir. On the supply side of the drought equation the main determinants are meteorological and hydrological. It is the former that is given emphasis in this article.
