chubasco

Chubasco is a term used in Spanish-speaking regions to describe a heavy, brief rain shower that is often accompanied by gusty winds and, in some cases, thunder and lightning. It is usually caused by localized convective activity related to cumulonimbus clouds and is short-lived, typically lasting from several minutes to an hour or two. In maritime and coastal contexts, chubasco can refer to a squall with sudden wind shifts and rain that reduces visibility and creates rough sea conditions.

Geographically, chubascos are common in tropical and subtropical regions of the Americas and the Iberian Peninsula, especially along coastlines where convective activity is frequent. They frequently occur in the afternoon as surface heating intensifies and can form in clusters as part of a larger storm system. They may include hail in stronger events, though this is not required.

Impact and safety: Although short, chubascos can cause localized flooding, slippery roads, and temporary disruption in urban or rural areas. On ships or near the coast, they may produce sudden gusts that complicate navigation and trigger rough seas. People are advised to seek shelter indoors during a chubasco and avoid exposed locations during gusty winds and lightning.
