Issued at 5:44 am WST on Friday 18 February 2011

A Cyclone WARNING is current for coastal areas from Exmouth to Coral Bay.

A Cyclone WATCH is current for coastal areas from Onslow to Exmouth and Coral
Bay to Overlander, including Carnarvon and Denham.

At 5:00 am WST Tropical Cyclone Dianne, Category 2 was estimated to be
460 kilometres northwest of Exmouth and
690 kilometres north northwest of Carnarvon and was moving south at 6
kilometres per hour.

Tropical Cyclone Dianne is located well off the northwest coast and has started
to drift slowly southwards. Dianne is expected to continue moving southwards
during Friday and Saturday, and will most likely remain well offshore from the
WA coast. If the cyclone moves closer to the coast GALES with gusts to 100
kilometres per hour may develop in coastal areas between Exmouth and Coral Bay
during Saturday morning, extending south to Overlander Roadhouse during
Saturday afternoon and evening. Gales may also extend east to Onslow on
Saturday afternoon if the cyclone moves along a southeastwards track. The
destructive core of Dianne is not likely to affect the WA mainland.

Tides along the entire west coast are likely to exceed the high water mark over
the next few days, with flooding of low lying coastal areas possible between
Onslow and Shark Bay (Denham).
