El Nio temperature impacts Typical winterspring El Nio maximum temperature El Nio rainfall impacts Historical rainfall deciles from 12 moderate-strong El Nios Rainfall for September to November
Rainfall for December to February Indian Ocean Dipole (IOD) Negative IOD Positive IOD
Spring temperature outlooks Probability of above median maximum temperature for September to November 2015 Probability of above median minimum temperature for September to November 2015
Spring rainfall outlook September Probability of above median rainfall for September to November 2015 and the months September and October October Bushfire potential
Issued September 2015 Tropical cyclones Australian region 814 tropical cyclones (average 11) 27 coastal crossings per year (average 4) Western Australia Average of 5 tropical cyclones 2 coastal crossings
1 of which is Cat 3 or higher Last year: below average number of tropical cyclones average number of landfalls All tropical cyclones reached category 3 or above The 2014-2015 tropical cyclone season
Tropical cyclone outlook for WA TC Olwyn 12 March 2015, NASA Strong El Nio so less likely to see first cyclone before Christmas
Expect slightly below average number of cyclones (around 4) However still expect 2 coastal impacts
One coastal impact cat 3 or higher High impact tropical cyclones can occur in any season
2006/7 season only 3 cyclones but one was TC George Severe thunderstorms Severe thunderstorms can form at anytime of the season Severe thunderstorms produce any of the following: Hailstones 2cm diameter
Wind gusts 90km/h Flash flooding Tornadoes Photo by Chris Kent Heatwaves: Increased risk A heatwave is 3 days or more of above normal temperatures. Monitor forecasts available at
http://www.bom.gov.au/australia/heatwave/index.shtml Flood risk Streamflow outlook Soil moisture lower layer (August) August to October
Widespread major flooding is less likely in El Nio (more likely in La Nia) Floods can occur regardless of catchment conditions or climate influences
Localised flooding (due to TC's, storms, etc.) are always a possibility Summary 2015 another warmer than average year despite some cold outbreaks El Nio is a dominant climate driver of weather patterns this season although less of an influence in WA Changes in risk compared to normal warm season Increased risk of heatwaves in warm season Decreased risk of widespread flooding,
Localised flood risk remains possibility Increased risk of bushfire in many areas due to dry and warm conditions Severe thunderstorms are ALWAYS possible Slightly later start and slightly below average number of tropical cyclones but still expect 2 coastal impacts in WA
