yesterday at around 16:30 had a massive downpour of rain in sittingbourne, I could see at the top of the road what looked to be fog, but as it got closer I could see it was a thick wall of rain heading striaght for me, so I quickly turned all the headlights on etc.. and when this "wall" of rain hit my bus I thought the windscreen was going to cave in (and I was only doing 25mph!!) the rain came down so heavy that windscreen wipers couldnt cope, the wind picked up violently, sending this rain into "rain bands" and I thought I was in a hurricane suddenly!!! the road quickly turned into a river as well, really good freak weather lol
