Severe Thunderstorm

Normal Information
A severe thunderstorm is a weather based natural disaster. It is one of the most common natural disasters, but they are not very destructive. But don't assume they cannot cause damage - a thunderstorm can be called severe if it has winds in excess of 60 miles per hour, and 60 MPH or greater can do some substantial damage.

Facts
Severe thunderstorms usually form during really warm weather conditions. They can also form when warm moist air collides with cold dry air. They may also be forming from a rainstorm. However, they are extremely rare during cold months. Plus, severe thunderstorms cause most other natural disasters as well, such as floods, tornadoes, and even hurricanes. Sometimes, severe thunderstorms can be distinctively found from the ground due to a SHELFCLOUD. A shelfcloud is a cloud that hangs lower than it's surrounding clouds and is usually the leading edge of a strong thunderstorm. The damage done from a severe thunderstorm can rip shingles from roofs, damage mobile homes, break branches, break leaves away from trees, sometimes topple small or dying trees, blow around unanchored objects and sometimes even blow over high-profile vehicles, such as semi trucks with trailers.
