Real English Twenty-four: When it rains it pours

It has been raining all day.  In fact, on and off it has been pouring all day.  Pouring, then drizzling, then pouring again, then back to drizzling.  According to the weather forecast,  there might be thunder storms tonight and Typhoon #4 may be coming soon...(Does anyone know Typhoon #4's name?  I don't.)  In addition, there is a 40% or more chance of rain in Osaka for the next 6 days.  (I don't know about after that because that is as far as the forecast on yahoo goes.)  In America, there is an expression, "When it rains it pours."  Simply put, it means that,  "when good things happen, they tend to happen all at once and a lot...in the same manners, when bad things happen, they tend to happen all at once and a lot...sort of like a domino effect."

Take a whack at it and try to use this expression when the opportunity arises.
