Let's suppose tomorrow everywhere will be closed due to a heavy snowfall and subsequently the bad weather condition! The TV/radio announces / declares that tomorrow is a holiday for work, schools and universities! Which one of the following sentences would sound natural to a native speaker to indicate this message:
1 - The TV/radio announced an official closure tomorrow due to the weather.
2 - The TV/radio declared an official closure tomorrow due to the weather.
3 - The TV/radio announced a holiday tomorrow due to the weather.
4 - The TV/radio declared a holiday tomorrow due to the weather.
I am asking this question because:
I doubt which one of the verbs announce or declare would sound more natural when a clusure is publicly informed.
I am not confident if "official closure" is used frequently in this sense! If yes, then how?
To identify the frequency of using the term "official closure" VS the word "holiday" in this sense in English.
