Storm Spotting
Where severe storms are possible, storm spotting groups such as SKYWARN in the United States coordinate amateur radio operators and localized spotters to keep track of severe thunderstorms and tornadoes. Reports from spotters and chasers are given to the National Weather Service so that they have ground truth information to warn the general public. Spotting provides ground information and localized conditions that the National Weather Service might not know the extent or might not otherwise be aware of. They typically report events, such as structures struck by lightning, rotating wall clouds, funnel clouds--or conditions that exceed specific thresholds, such as extremely strong winds, significant hail or very heavy rainfall. The exact reporting thresholds can vary by region and may even dynamically change during a severe weather event. Spotters also give reports during winter storms, floods, hurricanes, and wildfires.
Other countries have similar programs, such as the Canadian spotting program Canwarn, the SkyWarn UK and the Tornado and Storm Research Organisation (TORRO) programs in the United Kingdom, and Skywarn Europe for several European countries.

Famous quotes containing the word storm:
“When the storm rattles my windowpane
I’ll stay hunched at my desk, it will roar in vain
For I’ll have plunged deep inside the thrill
Of conjuring spring with the force of my will,
Coaxing the sun from my heart, and building here
Out of my fiery thoughts, a tepid atmosphere.”
—John Ashbery (b. 1927)
