السلام عليكم ورحمة الله وبركاته
We've also been having a few tiny sandstorms here in Kuwait.. I ask Allah to make us all safe and sound.
There's a Dua'a for this if someone can find an english translation for it..
For those who are facing some kind of winds or storms, to say:
"اللهم إني اسألك خيرها وخير ما ارسلت له, وأعوذ بك من شرها وشر ما أرسلت له"
