IDW10800 Australian Government Bureau of Meteorology Western Australia Tropical Cyclone Outlook for the Western Region Issued at 2:00 pm WST on Thursday 26 March 2015 for the period until midnight WST Sunday 29 March 2015. Existing Cyclones in the Western Region: Nil. Potential Cyclones: At 1:00pm WST the remnants of ex-Tropical Cyclone Nathan was located over northern parts of the Joseph Bonaparte Gulf and is forecast to move into the Western Region (i.e. west of longitude 125E) on Friday. Due to how significantly the system weakened as it moved over the Northern Territory and the somewhat unfavourable environmental conditions that it is currently moving through, it is expected to be below tropical cyclone intensity when it reaches the Western Region. The majority of computer model guidance suggests that the system will remain below tropical cyclone intensity, however there is a window of time between Friday and Sunday when conditions are marginally more favourable and there is a slight risk of redevelopment. Likelihood of this system being a tropical cyclone in the Western Region on: Friday Low Saturday Low Sunday Low There are no other significant lows in the Western Region and none are expected to develop in the next three days. Likelihood of another system being a tropical cyclone in the Western Region on: Friday Very Low Saturday Very Low Sunday Very Low NOTES: The likelihood is an estimate of the chance of each system being a tropical cyclone in the Region for each day. Very Low: less than 5% Moderate: 20 to 50% Low: 5% to 20% High: over 50% The Western Region refers to the Indian Ocean between Longitudes 90-125E and south of 10S.
