Huge development, the wind is going to be massive tomorrow, 32kph from the NW, in other words HUGE tail wind into the final corner, and a huge tailwind going into turn 7 8 chicane, the most critical corner on the track. Head wind into turn 4 too.
This also means turn 5 will be more difficult to do without lifting because the cross wind is going to make the rear go light. It's going to increase braking distance into the final turn because the wind will make cars understeer, and they'll have the wind pushing them.
Lastly it also means that drafting and DRS is going to be much more powerful into turn 4. The leading and trailing car will both be affected on the final corner, and the wind will help through 1, 2, 3.
