What type of weather can a Norwester create?

Correct answer: Strong storm and rain

The direct answer is option A: a strong storm and rain. A Norwester is a violent pre-monsoon thunderstorm, especially common in eastern and northeastern parts of India. In Bengal it is popularly called Kal Baisakhi. It can produce strong winds, thunder, lightning and heavy showers, and it may damage crops, houses and trees even though the rain can be useful. The reasoning is: Norwesters form during the hot pre-monsoon period; intense heating and unstable air help thunderstorms develop; the result is a sudden storm with rain. Option A is correct because stormy wind and rain are the characteristic weather of a Norwester. Option B is wrong because permanent snowfall is not a normal result of this hot-season thunderstorm. Option C is wrong because a Norwester is a short storm event, not a long spell of hot, dry Loo. Option D is wrong because the defining feature is rainfall and storm activity, not complete dryness. The term does not mean a dry northwesterly wind here; it refers to a local thunderstorm. Memory cue: Norwester or Kal Baisakhi means thunder, strong wind and rain before the monsoon.
