It is always raining here and it is raining here all the time

[Rachel Adams]

If I am not talking about somebody's behaviour, but about the weather can I use present continuous to express irritation?
For example,

1. "It's always raining here."

2. "It's raining here all the time."

I must have been wrong when I thought that with "all the time" it is wrong to use the progressive. I saw it in an example in "English Grammar in Context" by Michael Vince in "u". The book says "is developing" is the correct answer.

Yes, you can.

On line U, I'd say "develop" or "are developed." Remember, courses is a plural noun, so is would be wrong.
