Hi, we had something similar last year where the gutter wasnt substantial enough to cope with some down pours, much like last weeks.
The water that was escaping the gutter was being blown back against a lower wall, where there was a not very obvious crack in the pointing (the mortar between your brickwork). This was how the water was getting in and showing up as damp on the internal wall. We were obviously worried about what affect this may have had on internal structures, joists etc, so had a damp specialist come in a assess it just incase. He gave us a long story that they would have to strip back the plaster and wall to take samples of the joists etc which may be rotten and need replacing and all at huge expense as you can imagine.
As this had only happened once in the 3 years we had been in the house, we took the gamble that the internal structures have not had long term water contact, damage etc. Got a builder to repair the gutter and repoint the section of wall that the water was being blown against and after many months (3or4 as it took ages!!), paint the internal wall once it had fully dried... no problem since and I had a chance to properly assess this with all the rain last week...
Basically, it may be as simple as repairing the gutter, repointing the section of wall and painting internall after allowing it to dry out properly.
Hope this helps.
