Is this a correct sentence "Because of [a or the] snow storm, he hasn’t started out until the day before yesterday."?

"Storm" is countable, so you need some kind of determiner. Alternatively, you could use a different noun - for example "Because of adverse winds...." (or, in this case, "Because of snowy conditions...).

The tense of the verb needs to be different, as you specify the time - would you like to think again and suggest an improvement? ;-)
