BOM says for Sydney
Cloud decreasing. Rain areas easing to isolated showers around the middle of the day, then likely increasing again tonight. The chance of thunderstorms from early this afternoon. Winds easterly 30 to 45 km/h tending westerly 25 to 35 km/h in the afternoon then tending northwesterly in the evening.
CMC have said it will go ahead rain hail or shine. 2 out of 3 aint bad.Had several calls with members opting out. Obviously its not a great day but if you are going drive safely especially if they let you out on track at the creek.
