Weather Hazards

PDF versionPDF version

Weather hazards impact the entire country, with enormous effects on the economy and public safety. Since 1980, weather/climate disasters have cost the U.S. economy more than $1.1 trillion. In an average year, the United States will be affected by five or six billion-dollar weather/climate disasters.

Weather hazards include hurricanes, tornadoes, thunderstorms, lightning, hail, winds, and winter weather. Many of these phenomena are related to atmospheric conditions that can be monitored and forecast.   Read more

Case Studies & Factsheets


Background In areas prone to winter precipitation, transportation infrastructure must be able to quickly respond to snow and ice on roadways. Ice removal is a vital service in these communities. Deicing chemicals melt ice by lowering the temperature at which it melts. They can also prevent new...

Defining the Problem Following a tornado, first responders need maps of the width and location (swath) of the damage area. The biggest challenge when integrating remote sensing into disaster response is timeliness. To be most useful, remote sensing imagery maps must reach emergency management...

Defining the Problem Hurricanes bring not only intense rainfall, but also high winds and flooding. This flooding is powered by the hurricane storm surge: a rise in coastal sea level caused by lowered barometric pressure and by wind blowing the ocean onto the land. The result is that waves and...

Flooding is a perennial hazard for rivers and coasts alike. Every year, flooding results in billions of dollars of damage and the loss of dozens to hundreds of lives across the United States. Efforts to mitigate this hazard rely on the work of geoscientists, planners, and communicators to assess...

Hurricane Rita made landfall at Sabine Pass on the Texas/Louisiana border at 7:40 UTC on September 24, 2005. Rita was a large category 3 hurricane with maximum sustained winds of about 100 kts (Knabb et al. 2006). According to NOAA forecast maps, at the time of landfall Hurricane force winds were...
