City could receive welcome downpour

Residents are crossing their fingers after forecasts Broken Hill could receive up to 120 millimetres of rain during the coming days.
Whilst it wouldn’t break the region’s ongoing drought, the welcome downpour could help fill local catchments.
Bureau of Meteorology Observer Phil Mew said that forecasts were “never 100 per cent”, but the odds for at least some rain looked good.
There is a 90 per cent chance of falls of 20-40mm tomorrow and 40-80mm on Saturday.
Today there is an 80 per cent chance the city would receive 1-5mm.
“We’ve got a system that’s developing bringing in moisture from the north-west and north-east that is going to interact with the moisture inflow from the Gulf of Carpentaria,” Mr Mew said yesterday.
“...With a system like this it can vary from basically getting nothing to anything between 20 to 40mm where thunderstorms have passed directly over those areas.
“It will be a good rain for here but unfortunately it’s unlikely to fall in the catchment areas for the Darling River when at this time we badly need it in that area.
“The rain event appears to be a little bit to the west of the area where it’s needed but that’s not to say a low pressure system doesn’t develop in the Coral Sea and influence the moisture build-up.”
Up to 200mm has been predicted for South Australia’s north-west from today until Saturday with the Bureau of Meteorology has already issuing a flood watch.
“Those flood warnings are more likely in tropical areas, not necessarily in this area, but it has been known to happen in the past,” Mr Mew said.
“That’s not to say we won’t receive a proper drenching.”
The city could also receive a shower or two on Sunday.
Mr Mew said it was too early to predict the chances of the Darling River catchment areas receiving enough falls to fill the system before Broken Hill runs out of water.
“The likelihood is if they do get rain, Cubby Station will get rid of the water it’s had sitting there for a while and it will take the fresh stuff from the Darling.
“We’ll get the stale water here.”
