Latest forecast is a bit better for rally.

Shakedown:
Looks like very heavy rain but not as bad as expected, might be possible to drive, mostly without boat :-) temperature low, +10..+11

Friday:
SS1, quite heavy rain eases a bit just before the stage and should be driveable, even with car but still very bad conditions.
SS2, SS3, very heavy rain overnight and in the morning. I was expecting the rain to stop before the stage and it looks like it will be the case. Weather should turn nice just before the stages, sun comes out. But are the roads still driveable? That is a big questionmark. I would not be so sure. Model predicts 220 mm of rain from now until the beginning of the stage.. usually models overestimate such things, because they are designed by using real data.. but such weather is so unique that it is most likely that it is overestimating a bit because history is too short.

Rest of the weekend will be most likely nice and dry Little risk of rain in some stages.

So, Thursday and Friday morning is critical. When roads and cars survive it, then it is good :-)
