Flood Threat Bulletin (FTB) 2023 operations will begin on Monday, May 1st, and run through the end of September. Available on the redesigned, the FTO will provide a daily assessment of flood potential across the state, a 24-hour precipitation map, and a 7 - 15 day flood threat outlook (updated Mondays and Thursdays).

You can also follow the Flood Threat Bulletin on Twitter @COFloodUpdates for updates.

Below are some of the products available:

  • Daily Flood Threat Bulletin - This product is issued daily before 11:00 am and is used to identify areas of the state that are at risk of flooding. Updates can be issued as needed by weather situation.
  • Fire Burn Forecast - The FBF is issued daily by 11AM for select, high-risk burn areas in Colorado (May to Sept). This standalone forecast system was created to separate the higher-sensitivity burn area forecasts from the existing FTB product, but complement the overall goals of the program.
  • Flood Threat Outlook - This product is an outlook of the flood threat and precipitation amount/probabilities in the state over the next 15 days. It is presented in an event-based format that focuses on periods of potentially wet weather, and a precipitation map is included when the forecast precipitation exceeds 0.5 inches for any area during an event duration. The Outlook is updated on Mondays and Thursdays by 3PM.
  • State Precipitation Map - An overview of recent precipitation and flooding conditions across the state, using MetStorm Live data, heavy rain reports, and flood reports.
  • Streamflow Tracker - This product is a summary table updated monthly (mid-month) reflecting the last month's streamflow conditions across the 14 major basins in Colorado.
