Srila Prabhupada explains:
When there are natural disturbances like blowing cyclones, too much heat or snowfall, and uprooting of trees by hurricanes, it is to be understood that the demoniac population is increasing and so the natural disturbance is also taking place. There are many countries on the globe, even at the present moment, where all these disturbances are current. This is true all over the world. There is insufficient sunshine, and there are always clouds in the sky, snowfall and severe cold. These assure that such places are inhabited by demoniac people who are accustomed to all kinds of forbidden, sinful activity.
SB 3.17.5 Purport
Daivika, painful condition created by the demigods. Just like there is hurricane all of a sudden. So many trees falls down, sometimes cottages devastated, overflood, excessive rain, overflood, famine, pestilence. You have no control. You cannot control. You can simply say, "In future." That's all. But there is no control.
Srila Prabhupada Lecture, Srimad-Bhagavatam 1.10.6, Mayapur, 21 June 1973
When one attains self-realization, the brahma-bhuta [SB 4.30.20] stage, one knows that whatever happens during his life is due to the contamination of the modes of material nature. The living being, the pure soul, has nothing to do with these modes. In the midst of the hurricane of the material world, everything changes very quickly, but if one remains silent and simply observes the actions and reactions of the hurricane, he is understood to be liberated. The real qualification of the liberated soul is that he remains Krsna conscious, undisturbed by the actions and reactions of the material energy.
SB 6.12.15 Purport
Krsna held up the great Govardhana Hill in one hand for seven continuous days and saved all the people of Gokula from incessant rain, hurricane and hailstorm.
