La carte U.S. Drought Monitor est publiée tous les jeudis. Elle indique les régions des États-Unis qui sont en situation de sécheresse. La carte utilise cinq classifications : anormalement sec (D0), qui indique les zones qui peuvent entrer dans une période de sécheresse ou en sortir, et quatre niveaux de sécheresse : modérée (D1), sévère (D2), extrême (D3) et exceptionnelle (D4). Le Drought Monitor est le fruit d'un travail d'équipe depuis sa création en 1999. Il est produit conjointement par le National Drought Mitigation Center (NDMC) de l'université du Nebraska-Lincoln, la National Oceanic and Atmospheric Administration (NOAA) et le département de l'Agriculture des États-Unis (USDA). Le NDMC héberge le site Web du Drought Monitor et les données associées, et fournit la carte et les données à la NOAA, à l'USDA et à d'autres agences. Il est disponible sans frais sur droughtmonitor.unl.edu.
