SEVERE WEATHER WARNING

for DAMAGING WINDS and FLASH FLOODING

For people in the Adelaide and Mount Lofty Ranges, Lower Eyre Peninsula, Kangaroo Island, Yorke Peninsula, Mid North, Riverland, Murraylands, Upper South East and parts of the Eastern Eyre Peninsula districts.

Issued at 1:45 pm Thursday, 28 June 2007.

A small but deep low just south of Kangaroo Island is moving slowly eastwards. The low is expected to cross the Coorong coast tonight, then weaken as it moves further inland towards the Victorian border.

West to southwest winds, averaging 50-70 km/h with peak gusts to 120 km/h are already affecting parts of Eyre and Yorke Peninsulas and these damaging winds are expected to spread across the warning area during this afternoon. The winds should start easing after midnight. Locations which may be affected include Adelaide, Port Lincoln, Maitland, Murray Bridge and Victor Harbor.

Areas of rain and showers are occurring across the southern half of the state. The rain is forecast to become heavy later this afternoon in the Mid North and Mount Lofty Ranges, especially on and along the western slopes of the ranges. Rainfall totals of 100-150 mm are possible and this may cause flash flooding.

The State Emergency Service advises that people should:
* Move vehicles under cover or away from trees
* Secure or put away loose items around your property.
* Don't drive, ride or walk through flood water.
* Keep clear of creeks and storm drains.
* Stay indoors, away from windows, while conditions are severe.

The next warning is due to be issued by 4:45 pm.

Warnings are also available through TV and radio broadcasts, the Bureau's website at www.bom.gov.au or by calling 1300 659 215. The Bureau and State Emergency Service would appreciate warnings being broadcast regularly.
