2026 Spring Flood Outlook - Updated 2/26

Flood Outlook - updated Feb 26, 2026.

Key Points

The risk of spring flooding is below average.
The spring flood risk is based on the following factors: below average snowpack, near to below average soil moisture, and near to below average streamflow. Frost depth is deeper than normal and could increase runoff if there is heavy rain while the ground is still frozen. These conditions can and often change. A deeper snow pack could increase this risk.
This flood risk pertains to the underlying risk for the March to May time period as a whole. The risk may be higher with individual weather events. The greatest risk of flooding occurs with a rapid snowmelt or rain, especially on a frozen ground.
