Floods but no Feb 2017 rain recorded yet by BoM in Perth dam catchments

How bizarre is this – heavy rain and floods starting 9/10 Feb – but no Feb 2017 rain recorded yet – while rain is so easy to measure and record.
[1] BoM station Mundaring Weir 9031 has no data later than March 2016
[2] BoM station Victoria Dam 9216 is missing March and Jun, Oct to Dec 2016 nothing yet for 2017
[3] BoM station Churchman Brook 9010 has many periods in 2016 where no daily readings were taken – arrows. And no data yet for 2017
[4] BoM station Wungong Dam 9044 has all months for 2016 now and Jan 2017 as well(applause).
[5] BoM station Serpentine Main Dam 9115 has nothing after May 2016 – nothing for 2017 yet.
Can anybody recall anything like this tardy recording by the BoM anywhere else?
The rain that caused the floods from around York and Northam we saw on TV news was mostly from 9 Feb to 11 Feb and left this broad band of 100mm+ rain from Perth SW into the wheatbelt.

Cold day records smashed in Perth region

Thanks to Chris Gillham – From Perth Region (Western Australia not Scotland) Feb has been moderate so far over there.

Thats all I have time for – there must be a stack more. Watch these stunning cold records get fair coverage in the news media.

BoM trumpets January the warmest month on record for Sydney

The BoM blah-blahs on – Every station in the metropolitan area recorded its highest January mean temperature on record and most stations (including Sydney Observatory Hill) also broke records for mean maximum and minimum temperatures.
Not a word on the above BoM page of the ever growing urban heat island driving temperatures hotter for 150 years.
I see Richmond RAAF 67105 had Jan 2017 mean max = 34.1, mean min = 20.
I only have to check historic monthly mean max and min for Richmond – UWS Hawkesbury 67021 to find that 1946 equalled the Jan 2017 max of 34.1 and smashed the min by a whole degree. So obviously all the BoM claims for last month are rendered so pathetically tenous and lineball (without plugging in a “correction for UHI”) – what a disgusting propagandist organization the BoM has become.

BoM exaggerates again Canberra hottest January

Claiming Canberra had its hottest January – Hottest January on record sees Canberra’s power usage soarCanberra Airport 70351 had Jan 2017 mean max 32.8 but Queanbeyan Bowling Club 70072 in 1932 had a Jan mean max of 34.2 –
When you examine site differences, ponder the UHI growth in the ACT – Qbn UHI in 1932 – it looks too close to call. Definitely not a worthy record for the BoM to trumpet.

Perth dams rain data 2016

I am surprised the BoM and the WA Govt Water Corporation have not got their Perth dams rain data in order at the end of 2016. I have several posts on the subject through 2016 and have called for an audit. The latest was WA Water Corporation can not replace a couple of rain gauges in 2 months 27 Oct 2016
Water Corp are still showing the message re faulty instruments. Water Corp monthly rain data individual dams.WA Govt stations in Red
The three worst BoM stations. BoM stations in Blue.
Mundaring Weir daily rain 2016 no data post March
Victoria Dam daily rain 2016 data shambles
Serpentine Main Dam daily rain 2016 no data post May

Sydney record hot night – urban heat island never mentioned

Dear old Bureau of Meteorology up to usual tricks claiming a hottest evah record hot night for Sydney but ignoring the UHI. The record is not worth the paper it is printed on due to the huge urban heat island UHI.
Sydney weather: Overnight temperature is record high for December, BOM says
AWN lets you look around the region and see that the night of the 14th was warmest in the Sydney core stations, Obs Hill 27.1, Airport 27.5, Parramatta 27.5. Note RICHMOND RAAF (067105) at 23.6 further west in the UHI – the record there for Dec is 25 in 2000. The earlier RICHMOND RAAF (067033) 1928-1994 has 25.5 in 1990 as the record Dec night. All pointing to this warm night event being nothing special – unless you want to beat up global warming.

Perth heading for coldest September since at least 1906

Chris Gillham in Perth has been monitoring mean daily temperatures at Perth BoM sites and says Perth Airport 9021 is a shoo-in to have the coldest September mean since opening in 1944. Perth Metro 9225 in Mount Lawley has only been open from Jan 1994 replaced Perth Regional Office 9034 which commenced 1897 and underwent various moves before ending up in East Perth. Progress with temperature updates can be checked at AWN or the BoM.
Chris has a page discussing the history of various Perth weather stations since 1897. I will update as the final numbers are available and hope to include other Perth region sites such as Pearce – Jandakot – Medina etc It is amazing we can have a month like this in the teeth of the vast Perth urban heat island.
