Well, as Rob's blog told you days ago.. the official forecast for Wednesday now mentions strong south winds developing, and warmer temperatures (28 now instead of 24).
The wind forecast however could still be improved. The official forecast has south winds of 20 km/h becoming 40 gusting 60 "late in the day". I don't think so.. That pressure gradient will support winds of 30 km/h gusting 50 in the morning, increasing to 50 gusting 70 in the afternoon. The strongest winds will likely be between 2 and 8 pm. The strong winds, warm temperatures and low humidity will make for some very strong drying conditions. Not a good day for stubble burning!
