Understanding the 2026 National Hydrologic Assessment: A Quick Guide

The 2026 National Hydrologic Assessment (NHA), released on March 19, 2026, provides a comprehensive analysis of flood risks across the United States for the upcoming spring season. This assessment is crucial for communities, businesses, and individuals to prepare for potential flooding events.

What Does the 2026 NHA Reveal About Flood Risks?

The 2026 NHA indicates a normal to below-normal flood risk over much of the Continental U.S. (CONUS). This trend is primarily due to an abnormally warm and dry winter, resulting in low snowpack and dry soils, which help mitigate flood responses. However, minor to moderate flooding is expected in specific regions:

• Lower and Middle Mississippi Valleys: Minor to moderate flooding is anticipated.

• Lower Ohio and Missouri Valleys: Similar flooding risks are projected.

• Central and Northern Plains: Certain areas may experience minor flooding.

• Upper Peninsula of Michigan: Minor flooding is also possible.

In Alaska, the Yukon and Tanana river basins face above-normal flood risks due to above-normal snowpack and cold winter temperatures enhancing river ice conditions. Conversely, Southcentral Alaska, the Koyukuk River Basin, and parts of southwestern Alaska are expected to have below-normal flood risks. (weather.gov)
