In a question, the interrogative "O que" must stay at the beginning; omitting it changes the meaning.

Cultural Tip
In Brazil, people often talk about "a previsão do tempo" rather than just "a previsão". When you hear a forecast on TV or the radio, it's common to discuss how it will affect daily plans, especially for outdoor activities like beach trips, festivals, or soccer matches. Using "por causa da previsão" sounds natural, but adding "do tempo" makes it clearer and more idiomatic.
