The south east of the continent will remain very uncomfortable and potentially dangerous for human health and bushfire conditions through the remainder of the working week. The heat will not be displaced until a cool change develops late Friday or early Saturday for most of the south and into Canberra during Saturday afternoon. Along with high daytime temperatures the overnight minimums will be well above average
Here are some heat statistics to give a guide of some recent heatwave conditions:
Canberra Airport, In 2009 there were 3 days of consecutive 40 degree temperatures. This is pretty significant given there have only been 11 days above 40 in Canberra Airport’s history. Seven of those has occurred in the last 5 years. The 1979 heat wave was significant because it had five consecutive days in excess of 37 degrees. Hottest day on record is 42.2 and was recorded back in 1968. Data courtesy ABC Canberra and BOM.
Adelaide: 2009, 13 consecutive days over 33, 6 consecutive days above 40 and 4 consecutive days over 23.
Melbourne: 2009 12 consecutive days above 28, 5 consecutive days above 30 3 consecutive days above 43.
In Northern Australia the monsoon trough is the dominant feature with Cyclone Watch for a tropical low off the Northern Territory coast. Regardless of whether the low forms into a cyclone or not heavy rain is forecast across most of the Northern Territory and parts of Queensland and Western Australia through this week and the coming weekend.
