Is the drought coming to an end?

It's far too early to talk about the end of the drought, but there continues to be some very encouraging signs.

If we go back to July last year in Brisbane, we only recorded 1mm for the entire month.

So far this month we're up to 54mm and with more rain forecast this week, we should exceed the average of 63mm.

Remember this is historically our driest time of the year, so chances of recieving a huge downpour are limited. However regardless of history, we all know the weather is capable of throwing up an unusual event from left field.

Last August, an East Coast low dumped 731 mm in 24 hours at Rainbow Beach, breaking all previous records. Noosa had 480mm in that same week.

The all time 24 hour rainfall record in Queensland is 907mm recorded in 1893 at Crohamhurst.

But consider the fact that the deluge last year at Rainbow Beach was in winter, and recorded at one of our driest times.

At Crohamhurst it was in February, right in the middle of the wet season.

Brisbane also has an impressive record, in July 1965 we recorded 218mm in just one day.

So the point is, while history is reliable, it also proves the impossible can happen.

Adding to the optimistic outlook is a new feature on the Weather Bureau web site. It shows the chances of recieving a certain amount of rainfall over the next three months. Find it here. The current information states there's a 50 to 60% chance of 150mm and a 75 to 85% chance of 100mm by the end of September. If that does happen and then we head into some October storms, the outlook for the coming summer is very positive.

I love to hear your weather questions ... please add your queries below in the Comments area.

    Dear John,
    That's not a very good opening is it.

    How when and where, were the first records on australian weather conditions kept, is there a program that can make sense of the inconsistency and variations, thanks.

    The drought of 1895 to 1903 lasted 2921 days, the drought of 1911 to 1916 lasted 1826 days and the drought of 1939 to 1945 lasted 2192.

    Between 1885 and 1960 Murray-Darling River dried up on 48 occasions and the Murrumbidgee River stopped flowing from 1838 to 1842. Google: "Darling River dried up on 48 occasions,” and “The Murrumbidgee River stopped flowing for two years”.
