derecho
LowTechnical / Scientific / Weather Media
Definition
Meaning
A widespread, long-lived, straight-line windstorm associated with a fast-moving group of severe thunderstorms, often causing significant damage.
In meteorology, a specific type of severe convective weather event characterized by a swath of damaging winds extending more than 400 km (about 250 miles) and featuring severe wind gusts (often exceeding 93 km/h or 58 mph).
Linguistics
Semantic Notes
Primarily a meteorological term. Not to be confused with the Spanish adjective 'derecho' meaning 'straight' or 'right'. It is borrowed into English with a specialized, technical meaning.
Dialectal Variation
British vs American Usage
Differences
The term is used identically in both varieties but is more frequent in American English due to the higher frequency of such storms in North America (particularly the US Midwest). In the UK, similar phenomena are less common and may be reported with more generic terms.
Connotations
Conveys severity, scientific precision, and potential for widespread destruction. No significant difference in connotation between BrE and AmE.
Frequency
Much more common in American English weather reporting. In British English, it is a rare, specialized term known primarily to meteorologists and weather enthusiasts.

Examples
By CEFR Level
- The storm was very strong.
- The wind broke many trees.
- A powerful storm called a derecho caused a lot of damage in the state.
- The weather forecast warned of possible severe winds.

Learning
Memory Aids
Mnemonic
Think 'DERE-echo': The devastating winds of a derecho echo across a huge region in a straight line (from Spanish 'derecho' meaning 'straight').
Conceptual Metaphor
A derecho is a freight train of wind (emphasizing its power, speed, and linear path).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with the Russian word 'дерево' (derevo) meaning 'tree'.
- Do not translate directly as 'право' (pravo, 'right' or 'law') from Spanish. In English, it is exclusively a weather term.
Common Mistakes
- Mispronouncing it as /dɛrˈɛkoʊ/ or /ˈdɛrɪkoʊ/.
- Using it to describe any strong thunderstorm, rather than the specific, large-scale event.
- Spelling it as 'der echo' or 'deracho'.

FAQ
Frequently Asked Questions
No. While both are dangerous, a tornado involves rotating, funnel-shaped winds, whereas a derecho features widespread, straight-line winds from thunderstorms.
It comes from Spanish, meaning 'straight' or 'direct,' chosen to contrast with 'tornado,' which comes from the Spanish 'tornar' (to turn).
In the United States, they are relatively rare but significant events. Major derechos might occur a few times a year in susceptible regions like the Midwest and Mid-Atlantic.
Yes, meteorologists can forecast conditions favorable for derecho development, similar to forecasting severe thunderstorm outbreaks, though predicting the exact path and intensity remains challenging.
