Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation 'тропический шторм' as it's understood but non-standard; use 'тропический циклон' or 'тропический штормовой циклон' for precision, or 'тайфун'/'ураган' if above the wind threshold.
- Do not confuse with 'шторм' (storm) which is a more general term.
Common Mistakes
- Using 'tropical storm' interchangeably with 'hurricane' (a hurricane has higher wind speeds).
- Incorrect article use: 'There is tropical storm approaching' (missing 'a').
