Gust fronts create low-level [[wind shear]] which can be hazardous to planes when they takeoff or land.<ref>{{cite journal|author=Diana L. Klingle, David R. Smith, and Marilyn M.

If squall lines form over arid regions, a duststorm known as a [[haboob]] may result from the high winds in their wake picking up dust from the desert floor.<ref>{{cite web|author=Western Region Climate Center|date=2002|url=http://www.wrcc.dri.edu/ams/glossary.html#H|title=H|publisher=Desert Research Institute|accessdate=2006-10-22}}</ref> If outflow boundaries move into areas of the atmosphere which are stable in the low levels, such as over colder pockets of ocean or through the cold sector of [[extratropical cyclone]]s, they can create a phenomenon known as an undular bore, which shows up on satellite and radar imagery as a series of [[transverse wave]]s in the cloud field oriented perpendicular to the low-level winds.<ref>{{cite web|url=http://www.arpal.org/Pubbl/paper/eumetsat-mauritania.pdf|title=Outflow from convective storm, Mauritania and adjacent Atlantic Ocean (13 August 2006)|author=Martin Setvak, Jochen Kerkmann, Alexander Jacob, HansPeter Roesli, Stefano Gallino, and Daniel Lindsey|accessdate=2009-07-03|date=2007-03-19|publisher=Agenzia Regionale per la Protezione dell'Ambiente Ligure}}</ref>
