Description

Thunderstorms

What is a thunderstorm?
A thunderstorm is a rain shower during which you hear thunder. Since thunder comes from lightning, all thunderstorms have lightning.
Why do I sometimes hear meteorologists use the word “convection” when talking about thunderstorms?
Usually created by surface heating, convection is upward atmospheric motion that transports whatever is in the air along with it—especially any moisture available in the air. A thunderstorm is the result of convection.
What is a severe thunderstorm?
A thunderstorm is classified as “severe” when it contains one or more of the following: hail one inch or greater, winds gusting in excess of 50 knots (57.5 mph), or a tornado.
How many thunderstorms are there?
Worldwide, there are an estimated 16 million thunderstorms each year, and at any given moment, there are roughly 2,000 thunderstorms in progress. There are about 100,000 thunderstorms each year in the U.S. alone. About 10% of these reach severe levels.

The Durango and Silverton Narrow Gauge Railroad passes through the National Forest.

Theodore Roosevelt created the forest by proclamation on June 3, 1905. Forest headquarters are located in Durango, Colorado. There are local ranger district offices in Bayfield, Dolores, and Pagosa Springs.[2] President Barack Obama designated part of the forest as Chimney Rock National Monument by proclamation on September 21, 2012.[3]
