Note: 

A Sustained Wind Speed is found by averaging observed values of the wind over a one minute period or above. In India, IMD uses 3 mins average, while in USA they follow 1 mins average and in Japan they follow 10 mins average.

Wind Gusts is quick and sudden increase in the speed of wind (faster burst of wind). A wind gust usually lasts less than 20 seconds.
