Residents of southwestern WA kicked off the blankets last night with some places having their warmest September night on record. Donnybrook only dropped to 17.5 degrees overnight, ten degrees above average, which was its warmest September night in 108 years of records. In the South Coastal District, Albany had its warmest September night in at least 73 years which struggled to cool off to 16.6 degrees. Generally across the southwest, overnight temperatures stayed five to ten degrees above the September average and experiencing the warmest night since March. Narrogin only fell to 15.4 degrees which is only 0.1 degree short of the September record set 39 years ago. Mount Barker had its warmest night since February recording a minimum of 15.6 degrees. The warm night came after a particularly warm day this early in the season for southern WA on Wednesday. Along with the lingering warm temperatures from during the day, winds increased ahead of a cold front. This cold front is now moving across the southwest land divide bringing a drastically cooler day. At midday today, Perth was sitting at just 16 degrees, half of the max temperature recorded on Wednesday. The cold front is not only bringing cold and wet conditions but also the risk of damaging wind gusts. A severe weather warning for wind gusts up to 100km/h is current for areas southwest of a line from Mandurah to Katanning to Bremer Bay. So far Cape Leeuwin has seen gusts to 94 km/h and Rottnest Island had gusts up to 82 km/h. The unsettled weather is set to continue over the next couple of days as a series of fronts and troughs move through. More settled conditions should arrive from Sunday as a high pressure system builds to the west.
