Gust fronts are known to extend up to how many kilometers in front of a storm?

• A. 5 kilometers.
• B. 10 kilometers.
• C. 25 kilometers.
• D. 100 kilometers.

Answer: (C)

Gust fronts are the leading edge of air that pours out from a thunderstorm as the downdraft reaches the surface. This spreading out of cool, dense air creates a boundary that moves ahead of the storm and can bring strong, gusty winds along it. In typical weather and aviation contexts, this outflow boundary extends about 25 kilometers in front of the storm. The distance can vary with storm intensity and regional wind patterns, but 25 kilometers is the standard reference used to describe how far the gust front can reach. Other distances like 5, 10, or 100 kilometers either understate or overstate the common reach, making 25 kilometers the best-fit general estimate.
