Sound of Water

Noticed today and getting progressively more and more annoying that there is water trapped somewhere between the windscreen and top of the bonnet.

Could be just that where the water usually runs away has become blocked?

Any suggestions or similarities very much welcome.

Thanks
 
There are two drains either side of the windscreen, where the bonnet hinges are.

Pop the bonnet and give them a clear out, it is likely that these are blocked.

If it isn't this check your fluid levels, coolant, brake and windscreen.
