Jul.20 (GMM) Rain could affect this weekend's running of the German grand prix.
Although the preceding days at Hockenheim are expected to be very hot, severe weather - including heavy downpours - is predicted to be delivered by a cold front on Thursday and Friday.Rain is also possible on Saturday, with only a low chance of scattered showers forecast for race-day Sunday.Teams will be particularly hoping for a dry three hours of practice on Friday, given Bridgestone's extreme allocation of the hardest and softest compounds for Hockenheim.The tyre supplier's Hirohide Hamashima confirmed that weather at the German venue will be crucial."If it is hot then the super-soft will be a challenge to manage for stability and durability. If it is cold then ensuring the hard is in its temperature operating window will be a tough task," he said.
