Flash floods most often occur in dry areas that have recently received [[precipitation]], but they may be seen anywhere downstream from the source of the precipitation, even many miles from the source. In areas on or near [[volcano]]es, flash floods have also occurred after eruptions, when [[glacier]]s have been melted by the intense heat. Flash floods are known to occur in the highest mountain ranges of the [[United States]] and are also common in the arid plains of the Southwestern United States. Flash flooding can also be caused by extensive rainfall released by [[Tropical cyclone|hurricane]]s and other [[tropical storm]]s, as well as the sudden thawing effect of [[Ice jam|ice dam]]s.<ref>{{cite web|url=http://weathereye.kgan.com/cadet/flood/about.html |title=Flash Flood! |author=WeatherEye |year=2007 |publisher=Sinclair Acquisition IV, Inc. |access-date=2009-09-09 |url-status=dead |archive-url=https://web.archive.org/web/20090227073206/http://weathereye.kgan.com/cadet/flood/about.html |archive-date=2009-02-27 }}</ref><ref name="srh.noaa.gov" /> Human activities can also cause flash floods to occur. When [[dam failure|dams fail]], a large quantity of water can be released and destroy everything in its path.<ref name="srh.noaa.gov">{{cite web|url=http://www.srh.noaa.gov/mrx/hydro/flooddef.php|title=Definitions of flood and flash flood|author=[[National Weather Service]] Forecast Office [[Morristown, Tennessee]]|publisher=[[National Weather Service]] Southern Region Headquarters|date=2006-03-07|access-date=2009-09-09|archive-date=2006-09-29|archive-url=https://web.archive.org/web/20060929072411/http://www.srh.noaa.gov/mrx/hydro/flooddef.php|url-status=live}}</ref>
