I am so sorry i cant help but good luck
Aloha~! My name is Zalgo and I am here to help you out today. Those sort of conditions could be fore-boding/foreshadowing/warning that there will soon be a storm or that it will rain quite a lot. In the case of it being a storm, you should be a small room where there are no windows and nothing that is small that will fly towards you that could kill you.
I hope that this helps! :D
