  11. I remember as I was growing-up in the '80s and '90s we did have cyclones a number of times... cyclones used to develop in the Arabian Sea almost every year but move towards Gujarat most of the time and the impact would be felt in Mumbai as well. However, they did hit Mumbai at least 4-5 times in those decades. I remember clearly as school would be shut and we had to shut the windows at home too so that the strong winds do not cause any indoor damage.
