Northshore one of the busiest units in the Metro area
More than 60 FESA State Emergency Service volunteers from 16 units responded to almost 80 calls for assistance in the Perth metropolitan area and Great Southern region overnight.
The majority of the calls were for assistance with flooded homes requiring sandbagging, damaged roofs due to heavy rainfall requiring tarping, and trees fallen on to homes and garages.
In the metropolitan area up to 20 suburbs lost power, and the busiest SES units were Northshore, Bayswater and Rockingham with a total of 46 calls for assistance.
Acting Local Manager of Northshore SES, Nick Elliott said "We recieved a total of 17 calls for assistance between the hours of 2300hrs last night and 0900hrs this morning. Most of these related to flash flooding, with 4 or 5 relating to water ingress through roofs and gutters". Two rescue teams totalling 9 volunteers were mobilised.
More than 43mm fell on the city, while Mandurah received more than 60mm.
The massive fall last night means the city has already received more than 70mm for December, well above the average for the month of just 12.8mm.
Falls across the city were also widespread with Perth recording 43.6mm, Champion Lakes 34mm, Rottnest 36mm, Perth Airport 35mm and Swanbourne 30mm, mostly after 10pm.
ABC radio reports that in Perth that one woman's car filled with water after becoming stuck under the notorious Mt Lawley subway.
And a man had to climb from his car after it started floating away on Guildford Road, Baywswater, at the height of the downpour.
