This page answers the question: Can supernatural forces cause bad weather? This does not mean that supernatural forces are responsible for all bad weather, as natural forces can also cause storms.
God Can Be Responsible
Noah and the Ark
For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living substance that I have made will I destroy from off the face of the earth. And Noah did according unto all that the LORD commanded him. And Noah was six hundred years old when the flood of waters was upon the earth. And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood. Of clean beasts, and of beasts that are not clean, and of fowls, and of every thing that creepeth upon the earth, There went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah. And it came to pass after seven days, that the waters of the flood were upon the earth. In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. And the rain was upon the earth forty days and forty nights. (Genesis 7:4-12)
Joseph and Pharaoh's Dream
Pharoah Tells Joseph His Dream
And Pharaoh said unto Joseph, I have dreamed a dream, and there is none that can interpret it: and I have heard say of thee, that thou canst understand a dream to interpret it. And Joseph answered Pharaoh, saying, It is not in me: God shall give Pharaoh an answer of peace. And Pharaoh said unto Joseph, In my dream, behold, I stood upon the bank of the river: And, behold, there came up out of the river seven kine, fatfleshed and well favoured; and they fed in a meadow: And, behold, seven other kine came up after them, poor and very ill favoured and leanfleshed, such as I never saw in all the land of Egypt for badness: And the lean and the ill favoured kine did eat up the first seven fat kine: And when they had eaten them up, it could not be known that they had eaten them; but they were still ill favoured, as at the beginning. So I awoke. And I saw in my dream, and, behold, seven ears came up in one stalk, full and good: And, behold, seven ears, withered, thin, and blasted with the east wind, sprung up after them: And the thin ears devoured the seven good ears: and I told this unto the magicians; but there was none that could declare it to me. (Genesis 41:15-24)
Joseph Interprets Pharaoh's Dream
And Joseph said unto Pharaoh, The dream of Pharaoh is one: God hath shewed Pharaoh what he is about to do. The seven good kine are seven years; and the seven good ears are seven years: the dream is one. And the seven thin and ill favoured kine that came up after them are seven years; and the seven empty ears blasted with the east wind shall be seven years of famine. This is the thing which I have spoken unto Pharaoh: What God is about to do he sheweth unto Pharaoh. Behold, there come seven years of great plenty throughout all the land of Egypt: And there shall arise after them seven years of famine; and all the plenty shall be forgotten in the land of Egypt; and the famine shall consume the land; (Genesis 41:15-30)
The Seven Years of Plenty and the Famine
And Joseph was thirty years old when he stood before Pharaoh king of Egypt. And Joseph went out from the presence of Pharaoh, and went throughout all the land of Egypt. And in the seven plenteous years the earth brought forth by handfuls. And he gathered up all the food of the seven years, which were in the land of Egypt, and laid up the food in the cities: the food of the field, which was round about every city, laid he up in the same. And Joseph gathered corn as the sand of the sea, very much, until he left numbering; for it was without number...And the seven years of plenteousness, that was in the land of Egypt, were ended. And the seven years of dearth began to come, according as Joseph had said: and the dearth was in all lands; but in all the land of Egypt there was bread. And when all the land of Egypt was famished, the people cried to Pharaoh for bread: and Pharaoh said unto all the Egyptians, Go unto Joseph; what he saith to you, do. And the famine was over all the face of the earth: and Joseph opened all the storehouses, and sold unto the Egyptians; and the famine waxed sore in the land of Egypt (Genesis 41:46-49, 53-56).
Moses and Egypt
And the LORD said unto Moses, Stretch forth thine hand toward heaven, that there may be hail in all the land of Egypt, upon man, and upon beast, and upon every herb of the field, throughout the land of Egypt. And Moses stretched forth his rod toward heaven: and the LORD sent thunder and hail, and the fire ran along upon the ground; and the LORD rained hail upon the land of Egypt. So there was hail, and fire mingled with the hail, very grievous, such as there was none like it in all the land of Egypt since it became a nation. And the hail smote throughout all the land of Egypt all that was in the field, both man and beast; and the hail smote every herb of the field, and brake every tree of the field. (Exodus 9:22-25)
Elijah and Ahab
And Elijah the Tishbite, who was of the inhabitants of Gilead, said unto Ahab, As the LORD God of Israel liveth, before whom I stand, there shall not be dew nor rain these years, but according to my word. And the word of the LORD came unto him, saying, Get thee hence, and turn thee eastward, and hide thyself by the brook Cherith, that is before Jordan. And it shall be, that thou shalt drink of the brook; and I have commanded the ravens to feed thee there. So he went and did according unto the word of the LORD: for he went and dwelt by the brook Cherith, that is before Jordan. And the ravens brought him bread and flesh in the morning, and bread and flesh in the evening; and he drank of the brook. And it came to pass after a while, that the brook dried up, because there had been no rain in the land...And it came to pass after many days, that the word of the LORD came to Elijah in the third year, saying, Go, shew thyself unto Ahab; and I will send rain upon the earth...And Elijah said unto Ahab, Get thee up, eat and drink; for there is a sound of abundance of rain. So Ahab went up to eat and to drink. And Elijah went up to the top of Carmel; and he cast himself down upon the earth, and put his face between his knees, And said to his servant, Go up now, look toward the sea. And he went up, and looked, and said, There is nothing. And he said, Go again seven times. And it came to pass at the seventh time, that he said, Behold, there ariseth a little cloud out of the sea, like a man's hand. And he said, Go up, say unto Ahab, Prepare thy chariot, and get thee down, that the rain stop thee not. And it came to pass in the mean while, that the heaven was black with clouds and wind, and there was a great rain. And Ahab rode, and went to Jezreel. (1 Kings 17:1-7, 18:1, 18:41-45)
But Jonah rose up to flee unto Tarshish from the presence of the LORD, and went down to Joppa; and he found a ship going to Tarshish: so he paid the fare thereof, and went down into it, to go with them unto Tarshish from the presence of the LORD. But the LORD sent out a great wind into the sea, and there was a mighty tempest in the sea, so that the ship was like to be broken. (Jonah 1:3-4)
Satan Can Be Responsible
And the LORD said unto Satan, Behold, all that he hath is in thy power; only upon himself put not forth thine hand. So Satan went forth from the presence of the LORD....While he was yet speaking, there came also another, and said, Thy sons and thy daughters were eating and drinking wine in their eldest brother's house: And, behold, there came a great wind from the wilderness, and smote the four corners of the house, and it fell upon the young men, and they are dead; and I only am escaped alone to tell thee. (Job 1:12,18-19)
Either God or Satan can be responsible for bad weather. This is not to say that every hurricane, tornado, flood, drought, or any other bad weather is attributable to the supernatural. Natural forces can certainly cause these phenomena as well. This is, however, to say that supernatural forces, both good and evil, can be responsible.
