Heavy rain in southwestern WA
Another unusually cold day across the continent

A band of moisture streams southeast ahead of cooler air moving in from the southwest behind a slow-moving cold front. The animation shows the situation at the 850hPa pressure level (about 1.4km above sea level) at 10pm Monday and 10am and 10pm today. Note how the relatively narrow moisture band pauses over the southwest during the first two frames. Fiorino

A band of moisture moving down from the northwest ahead of a frontal system stalled over far southwestern WA today giving the coast south of Perth 50 to 75mm over a 12 to 18 hour period. Busselton Airport recorded 77mm between 9am and 9pm, with downpours of 20mm in the hour to 3pm and 13.8mm in 18 minutes to 8.08pm.
