Weather Hazards

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

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...

Beaches serve as a natural buffer between the ocean and inland communities, ecosystems, and natural resources. However, these dynamic environments move and change in response to winds, waves, and currents. During extreme storms, changes to beaches can be great, and the results are sometimes...

In September 1998, Tropical Storm Frances caused severe beach and dune erosion along the Gulf shoreline of the southeast Texas coast. This erosion placed many beach houses in danger of being undermined or damaged during subsequent storms and gradual shoreline retreat. To help prevent such damage,...

A tornado is a violently rotating column of air extending from a thunderstorm to the ground. In an average year, about 1,000 tornadoes are reported across the United States, resulting in 80 deaths and over 1,500 injuries, according to the National Oceanic and Atmospheric Administration. The most...

On May 22, 2011, a column of rotating air spawned a massive EF-5 tornado, with wind speeds greater than 200 miles per hour, over the city of Joplin, Mo. The twister caught the city off guard, leaving 158 people dead and injuring more than 1,000 people, making it the deadliest tornado in the United...

The impact of hurricanes in the United States is an average of 20 deaths and $5.1 billion per year (excluding the 2005 season). On average, ten tropical storms form during the Atlantic hurricane season, with 6 becoming hurricanes and 2-3 becoming major hurricanes. However, tropical cyclone activity...
