What if there is heavy rain on the day of your trip? 😥
You might be worried whether your flight will take off safely or if there will be cancellations.
When it comes to takeoffs and landings, aircraft are more affected by wind speed than by rainfall.
If it is rainy but the wind is light, takeoff and landing can proceed without serious issues.
However, there is a higher risk of cancellations in following situations:
🌧️ When it rains at a rate of 30mm per hour or more
🌪️ When strong winds or wind shear occur
❄️ When a heavy snowfall advisory is issued
* Wind shear: A type of turbulence where the wind direction or speed changes suddenly
Following the aviation weather alert standards, if any of these conditions exceed the specified thresholds, flight delays and cancellations can be occured.
For more details, please refer the table below.
