A low pressure system is moving southwards off the west coast bringing heavy rainfall and abnormally high tides with damaging possible in coastal areas.
Weather Situation: At 9:00am WST Saturday 6 February, a low pressure system was located 85 kilometres southwest of Denham and 160 kilometres northwest of Kalbarri. The low will move southwards during the weekend while remaining offshore from the west coast. It is expected to lie due west of Geraldton around 3:00am Sunday and pass west of Perth Sunday evening before passing close to the Southwest Capes in the early hours of Monday morning.
The low will produce strong to gale force winds over the ocean as it moves south and gusty winds over land, with heavy rainfall only on the southern side of the system.
HEAVY RAINFALL is possible over the Central West today, extending into the Lower West this afternoon and evening, including the Perth Metropolitan area. The heavy rain will extend across the South West district early on Sunday. Daily totals of 20 to 40 millimetres are forecast with isolated falls up to 100 millimetres possible. Once the low is south of an area rainfall will ease.
Tides are also likely to be higher than predicted along the west coast north of Perth on Saturday and north of Augusta on Sunday. In these areas tides may rise ABOVE THE NORMAL HIGH TIDE MARK with ROUGH SEAS and POTENTIAL FLOODING OF LOW-LYING COASTAL AREAS with the evening high tides.
Fresh and gusty easterly winds will continue south of the system. As the Low moves past, winds will shift northerly and in coastal areas DAMAGING WINDS averaging 60 to 70 kilometres per hour with peak gusts to around 100 kilometres per hour are possible. Once the low is south of an area winds will ease.
