Flood Mapping

"Flooding is the most frequent severe weather threat and the costliest natural disaster facing the nation. Ninety percent of all natural disasters in the U.S. involve flooding."

In Buffalo County, flooding is the most expensive type of natural disaster.
Since 2014 the Buffalo County GIS / Land Information office has worked to build & deploy public flood awareness tools as part of its ongoing modernization efforts.

NWS Situation Report

"The Hazardous Weather Outlook (HWO) is designed to be a “Heads Up” to expected hazardous weather and its potential impact for the entire seven-day forecast period. The HWO provides a “first-stop” for customers to find information on potential hazardous weather, its timing, its location and its impact. Weather Forecast Offices (WFOs) in Central Region issue a HWO a minimum of once each day, between the hours of 4 a.m. and 7 a.m. local time. Other releases are based on changes in hazardous weather or customer needs. The experimental Situation Report will build upon the traditional HWO by adding graphics, web links and other relevant dynamic content."
