Funnel cloud

<p>A funnel cloud is a <a href="/facts/Funnel/nA6YywU2">funnel</a>-shaped <a href="/facts/Cloud/KDgo0Wqu">cloud</a> of condensed water droplets, associated with a rotating column of wind and extending from the base of a cloud (usually a <a href="/facts/Cumulonimbus_cloud/DPWNqTDE">cumulonimbus</a> or <a href="/facts/Cumulus_congestus_cloud/KdNLMm3Y">towering</a> <a href="/facts/Cumulus_cloud/s2ymz6vz">cumulus cloud</a>) but not reaching the ground or a water surface. A funnel cloud is usually visible as a cone-shaped or needle like protuberance from the main <a href="/facts/Cloud_base/nvmFYN5K">cloud base</a>. Funnel clouds form most frequently in association with <a href="/facts/Supercell/xdUV0gdP">supercell</a> <a href="/facts/Thunderstorm/F6hUzuAu">thunderstorms</a>, and are often, but not always, a visual precursor to <a href="/facts/Tornado/HSGNQzHa">tornadoes</a>. Funnel clouds are visual phenomena, but these are not the <a href="/facts/Vortex/K6oeqcuX">vortex</a> of <a href="/facts/Wind/Nt0QIu5B">wind</a> itself.
