Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 35-36

Sanskrit:

अपि न: स्मर्यते ब्रह्मन् वृत्तं निवसतां गुरौ ।गुरुदारैश्चोदितानामिन्धनानयने क्व‍‍चित् ॥ ३५ ॥प्रविष्टानां महारण्यमपर्तौ सुमहद् द्विज ।वातवर्षमभूत्तीव्रं निष्ठुरा: स्तनयित्नव: ॥ ३६ ॥

ITRANS:

api naḥ smaryate brahmanvṛttaṁ nivasatāṁ gurauguru-dāraiś coditānāmindhanānayane kvacit

Translation:

O brāhmaṇa, do you remember what happened to us while we were living with our spiritual master? Once our guru’s wife sent us to fetch firewood, and after we entered the vast forest, O twice-born one, an unseasonal storm arose, with fierce wind and rain and harsh thunder.

Purport:

Śrīla Viśvanātha Cakravartī explains that this storm arose during winter and was therefore unseasonal.
