1988–1990 North American drought
drought in North America between 1988-1989
The 1988–1990 North American drought ranks among the worst episodes of drought in the United States. This multi-year drought began in most areas in 1988 and continued into 1989 and 1990 (in certain areas). The drought caused $60 billion in damage ($163 billion 2026 USD) in United States dollars, adjusting for inflation. The drought occasioned some of the worst blowing-dust events since 1977 or the 1930s in many locations in the Midwestern United States, including a protracted dust storm, which closed schools in South Dakota in late February 1988. During the spring, several weather stations set records for the lowest monthly total precipitation and the longest interval between measurable precipitation, for example, 55 days in a row without precipitation in Milwaukee. During the summer, two record-setting heatwaves developed, similar to those of 1934 and 1936. The concurrent heat waves killed 4,800 to 17,000 people in the United States. During the summer of 1988, the drought led to many wildfires in forested western North America, including the Yellowstone fires of 1988.
At its peak, the drought covered 45% of the United States. That was far less area than the Dust Bowl, which covered 70% of the United States, but the drought of 1988–1990 not only ranks as the costliest drought in United States history, it was one of the costliest natural disasters in United States history.

Why this record matters
The phrase “drought in North America between 1988-1989” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 31, 2026. The linked authority identifier is Q4584260. Authority coordinates are 46.000, -94.000. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1988, 1990, 1989 and 2026.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
