For the 24 hours till 9 am 17 June, a large swathe of Eastern inland Australia has received much needed rainfall with some reasonably large totals occurring. There are regions that have been dry and in drought but the regions are receiving worth while falls. This is not an event that will break any drought but it is significant as cropping lands are benefiting the most. The best falls for the period are:-

Far west New South Wales;

Broken Hill - 21 mm.
Burta - 30 mm.
Darlington Point - 36 mm.
Coleambally and Hillston - 37 mm.
Morundah - 38 mm.
Pooncarie - 71 mm (Highest in NSW).

A large area across the north west slopes and plains received falls ranging from 25 mm to 49 mm with the best falls occurring at:-

Caroda - 61 mm.
Nundle - 59 mm.
Terry Hie Hie - 55 mm.
Garah - 54 mm.
Mungindi - 52 mm.

Similar falls also occurred across the southern and south central inland of Queensland with the better falls occurring around Roma and Mitchell. The best falls include:-

Havelock - 63 mm.
Mictchell - 62 mm.
Southwood - 55 mm.
Roma - 53 mm.

Widespread falls of 25 to 49 mm occurred in this area.

During the period 9 am to 6 pm 17 June, further rainfall has occurred. A large area of cloud lingering across the south west slopes of New South Wales and North East Victoria has delivered worthwhile falls to the northern areas of North East Victoria including 30 mm at Hunters Hill, 15 mm at Albury while Wagga Wagga (NSW) collected 20 mm during this period. Most areas within this region collected at least 10 to 20 mm from the cloud mass during the period.

The rainfall plot from the Bureau of Meteorology (Water and the Land) is provided and dated 17/6/2015.

Tropical storm Bill expected landfall across Texas

Over the past 24 hours, a Tropical Depression tracking north towards the southern USA coastline has intensified into a significant storm event. The National Weather Service has now called the storm "Tropical Storm Bill".

As the storm makes its final approach towards the Texas coastline, a number of storm alerts have been issued for the coastline between Galveston and Corpus Christi. It is identified that the storm is producing winds to 45 knots with peak gusts to 55 knots. It is not expected to develop into a hurricane but with significant convection occurring, this event is expected to unleash heavy rain and significant thunderstorm activity across Texas. Weather warnings are being issued or expected to be issued for cities such as Houston, Dallas and Oklahoma City. The main threat is flooding across saturated areas.

In addition to the storm track now produced by CIMSS (June 15 2015), a satellite image of the storm taken from MODIS (NASA - 15 June 2015) clearly shows the storm approaching Texas. The photo also shows convective storm activity developing ahead of the main storm across southern Texas.

This is expected to be a major weather event given the alerts that are now issued across swathes of southern Texas.

Overnight, a band of moderate rain crossed through New South Wales and northern Victoria. Generally, rainfall from the event was reasonably even and widespread. There were widespread 10 mm to 25 mm falls over large areas with the best falls to 9 am 16 June being:-

Bourke - 43 mm.
Darlington Point - 34 mm.
Corowa, Nyngan and Trangie - 33 mm.
Dubbo - 30 mm.
Kilfera - 28 mm.
Coleambally - 25 mm.

While not drought breaking in nature, they are useful totals. The rain is falling where it is needed the most.

Additionally, there were some reasonable totals around the Wollongong region (Illawarra) with many rain gauges recording between 25 and 39 mm.

For the period 9 am to 6 pm June 16, the rain band passed through Sydney producing light rain. The best falls for the 9 am to 6 pm period occurred over the north west slopes and plains of New South Wales being 18 mm at Tambar Springs, 17 mm at Mullaley and 15 mm at Gunnedah.

A large region of the north west has received between 10 and 20 mm during the period. More rain will occur and as identified in earlier posts, more significant rainfall totals are expected in many regions.

The rainfall plot for New South Wales and Victoria till 9 am June 16 from the Bureau of Meteorology - Water and the Land is attached.
