Because wind is invisible, it is hard to see a tornado unless it forms a condensation funnel made up of water droplets, dust and debris. Tornadoes can be among the most violent phenomena of all atmospheric storms we experience. The most destructive tornadoes occur from supercells, which are rotating thunderstorms with a well-defined radar circulation called a mesocyclone. (Supercells can also produce damaging hail, severe non-tornadic winds, frequent lightning, and flash floods.)”</span><br />&nbsp;</div><div><div style='font-family:inherit; text-align:center;'><img src='https://fedmaps.maps.arcgis.com/sharing/rest/content/items/2935e90c2e3a4713beac0292d1545bc8/data' alt='USDOC NOAA Tornadoes _ 800x400 _ screen capture' /><br /><span style='font-size:large;'><i>EF-5 Tornado (May 22, 2011) near Joplin, Missouri</i></span></div><div style='font-family:inherit; text-align:center;'>&nbsp;</div><div style='font-family:inherit; text-align:left;'><span style='font-size:large;'><strong>Data currency:</strong></span><span style='font-family:inherit; font-size:large;'> </span><span style='color:#000000; font-family:inherit; font-size:large;'>December 30, 2024</span></div><div><div style='font-family:inherit;'><font style='font-family:inherit; font-size:large;'><strong>Data source:</strong>&nbsp;</font><a style='color:rgb(0, 121, 193); font-family:inherit; text-decoration-line:none;' target='_blank' href='https://www.spc.noaa.gov/gis/svrgis/' rel='nofollow ugc noopener noreferrer'><font style='font-family:inherit; font-size:large;'>Storm Prediction Center</font></a></div><div><font><strong>Data modifications:&nbsp;</strong></font><span style='color:#000000; font-size:large;'><font>Added field "Date_Calc"</font></span></div><div style='font-family:inherit; font-size:large;'><font><strong>For more information:&nbsp;</strong></font><a style='font-family:inherit; font-size:15px;' target='_blank' href='https://www.nssl.noaa.gov/education/svrwx101/tornadoes/' rel='nofollow ugc noopener noreferrer'><span style='font-size:large;'><font>Severe Weather 101 - Tornadoes</font></span></a><font>;&nbsp;</font><a style='color:rgb(0, 121, 193); font-size:15px; text-decoration-line:none;' target='_blank' href='https://www.nssl.noaa.gov/research/tornadoes/' rel='nofollow ugc noopener noreferrer'><span style='font-size:large;'><font>NSSL Research:&nbsp;Tornadoes</font></span></a></div><div style='font-family:inherit; font-size:large;'><font><strong>Support documentation:&nbsp;</strong></font><a style='color:rgb(0, 121, 193); font-family:inherit; font-size:0.9375rem; text-decoration-line:none;' target='_blank' href='https://www.spc.noaa.gov/wcm/data/SPC_severe_database_description.pdf' rel='nofollow ugc noopener noreferrer'><span style='font-size:large;'><font style='font-family:inherit;'>SPC Tornado, Hail, and Wind Database Format Specification</font></span></a></div><div style='font-family:inherit;'><span style='font-size:large;'><font style='font-family:inherit;'><strong>For feedback, please contact:</strong>&nbsp;</font></span><a style='color:rgb(0, 121, 193); font-family:inherit; text-decoration-line:none;' href='mailto:[e-mail]' target='_blank' rel='nofollow ugc noopener noreferrer'><span style='font-size:large;'><font style='font-family:inherit;'>[e-mail]</font></span></a></div><div style='font-family:inherit;'>&nbsp;</div><div style='font-family:inherit;'><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px; text-align:center;'><span style='font-size:x-large;'><font style='font-family:inherit;'>National Oceanic and Atmospheric Administration</font></span></div><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif;'>&nbsp;</div><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif;'><span style='color:#000000; font-size:large;'><font style='font-family:inherit;'>Per&nbsp;</font></span><a style='color:rgb(0, 121, 193); font-family:inherit; text-decoration-line:none;' target='_blank' href='https://www.noaa.gov/about-our-agency' rel='nofollow ugc noopener noreferrer'><span style='font-size:large;'><font style='font-family:inherit;'>NOAA</font></span></a><span style='color:#000000; font-size:large;'><font style='font-family:inherit;'>, its mission is “To understand and predict changes in climate, weather, ocean, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources.”</font></span></div></div></div></div>
