My old National Night-Time Hot Spot (NNTHS) may have been vanished but several more candidates are blinking away 2013-2020. I see there are “cool spot” anomalies repeating too.
BoM data is so tortured they can not rid these maps of obvious errors. Larger map.

BoM rainfall maps NSW north coast floods
I thought it was interesting in view of the NSW north coast floods in the headlines lately to compare the current month Rainfall percentages map to a few other months of notable rainfall. Readers can very easily change the BoM map specs to view other months or parameters. I used the Kempsey (Wide Street) 59017 monthly rainfall data as a guide and made maps for – Feb 1929 which showed a larger area plus 400% on the NSW North Coast. June 1967 showed a much larger area as did June 1950. There would be many more flood events but these caught my eye. Many people in various parts levitra 10 mg www.dentech.co/ of the world at this time are suffering from erectile dysfunction. It helps to gain fuller and stronger erection and maintain love for a viagra sale in india long time. buy generic viagra The only hitch is that the man has to indulge in sexual activity. But, a man may also suffer from the lack of ability to develop or on line levitra else maintain an erection of penis arise when a man sexual get encouraged. If any readers can obtain current month outflows to sea data for the NSW North Coast – and or historic monthly flows to sea data please pass on. For the Sydney region Nov 1961 is mentioned as the worst flood in living memory. June 1950, Feb 1956 and Apr 1988 maps are worth a look. June 1867 is reported as the worst ever – way higher than this month – and looking at monthly rain data I see Parramatta 66046 records over 500mm in May 1889 and March 1892 – too early for maps.
It does seem out of touch that in this day and age we still have so many Sydney houses flood prone.
BoM rain Outlook stellar fail for March
Checkout the rainfall Outlook for March and compare with month to date rainfall percentages for Australia and you will see the small areas on the east coast where BoM can claim success. Set against the vast areas of heavy March rainfall elsewhere across wide brown land where BoM Outlook has had stellar failure.
Below here actual rainfall percentages to the 23rd March
Cool summer 2021 for wide brown land
Summer daytime temperatures across Australia were cooler than the average from 1910 even with the graph built from the BoM tweaked ACORN temperature series where the past has been cooled to fit IPCC dogmas. Checking out the summer Outlooks against the real world – the Minimum Temperature Outlook takes the prize for utter failure. How could BoM models predict such an extreme Outlook?
Ask me if you can not find something. With that basic ingredient, the medicine producing companies have produced a lot of medicines they are, in short, Kamagra, Kamagra oral jelly, Zenegra, Silagra, levitra cost of sales , Forzest etc. If you are also one of them and seeking for an economical order prescription viagra remedy.

On one hand, you have stressed-out loved ones urging, pleading, and even screaming warnings about the impending doom; begging you not to go out sildenafil free shipping into the raging storm. Enjoy the way the BoM is promoting warming stories in the face of the cool summer. Ningaloo Nino: The climate phenomenon worrying scientists 1Mar21
Perth enjoys all time record cold December morning
Thanks for headsup from David. Perth Metro recorded a minimum temperature of 6.6C today.
The previous record of 7.9 from 2007 well & truly smashed and of course headlines all over. Also beats the old Regional Office record which was 8.6 from 1979. And that is in the middle of the huge Perth urban heat island – which must prove something about climate change.
BoM November Outlook fails already
I noticed the BoM minimum temperature Outlook map for November was a blaze of red predicting that huge areas of the wide brown land had an 80% chance of having way-way-hot nights. And not 1 square centimetre of Oz was predicted to enjoy cooler than average nights. Larger map.
If you go to the current month Min anomaly map and choose weekly – you can tick back to earlier weeks and it is obvious the BoM min t Outlook map for Nov is a monster fail.
BoM introduces new rainfall maps
Lance gave me the heads up – BoM says at the old AWAP rain maps page – [Please visit the new Rainfall maps page and update your links.
The Bureau of Meteorology has upgraded its monthly gridded rainfall analysis. The enhanced analysis known as Australian Gridded Climate Data (AGCD) employs improvements in statistical modelling and scientific techniques.
The new page also includes the daily data and the previously separate rainfall archive and RMSE pages.] Here is the Old AWAP map for calendar 2019 – and here is the new AGCD map for calendar 2019 – I am surprised at the differences. Hoping readers search around various periods and post any interesting differences.
July rain outlook fails many points
As July draws to a close the Australian current month to date rain percentages bear little resemblance to the July rain Outlook.
As our commenter has reported – now August is here we can see the BoM max and min anomaly maps for July and you can compare to the way-way hotter looking 25th June Outlooks for July max and min.
SE Australia cold start to June
The ABC reports Adelaide CBD records coldest morning since 1944 as ice forms on River Torrens – I had been watching this cold spell for a few daze. Cooma Airport AWS 70217 has seen the coldest first 10 days of June (-3.24) since 2000 which averaged -3.81. I have not checked Canberra. The Minimum Temperature Outlook for June issued on 28 May predicts warm anomalies for June. The Minimum Temperature maps for 5th June shows the SE Australian cool patch and you can easily explore forward or back from there as the month progresses.
ABC reports experiences of Lake Conjola fires
At a time when the Royal Commission into National Natural Disaster Arrangements is sounding like a “festival of AGW/climate change” with BoM spokes talking up “dire” climate change – 
the ABC can not quote anybody that questions the wisdom of communities such as Lake Conjola.
I have not heard a word about decades of increasing south coast populations – increasing post WWII subdivision of “bush blocks” by Councils taking population into areas of elevated fire risk – increased areas of National Parks(NSW State) which were previously forests that were managed better and simultaneous decreased management of vegetation adding to fire risk. This Google map of Lake Conjola shows clearly the extent to which areas of housing abut hard up against fire prone native bush. Large map. 
Disasters waiting to happen with the clear warning of Tathra in March 2018 then the drought extends adding to fuel combustibility. If anybody knows of historic population trends for any south coast shires please post. I note too that housing blocks at Malua Bay south of Batemans Bay have been advertised on TV for months with forest pictured right near housing. I think I read where Minister Andrew Constance is from there. I hear nothing on TV news about reducing future fire risk or not rebuilding in danger.
