pouring, raining very heavily

2. Face like thunder
being clearly very angry or upset

3. Storm in a teacup
exaggerating a problem, anger or worry about something unimportant
Their debate was only a storm in a teacup – actually neither of them took the problem too serious.

4. Chase rainbows
waste time trying to achieve something impossible

7. Snowed under
having too much to do
I’d love to help you, but I’m completely snowed under at the moment.
Could you come over and fix the tap in the bathroom? But of course, only if you aren’t snowed under, it’s not so urgent.
8. Under the weather
ill, sick, feeling unwell, sad or lacking energy
Do you mind if I stay out of work today? I’m feeling under the weather, I may have the flu.
