Parts of South Australia hve been particularly dry for more than six
months, with significant relief still weeks away.
Adelaide, Port Augusta and Whyalla have all had below average rainfall
for every month since June or July last year. Most other inland
locations have only seen above average rainfall in one or two months
during this period.
Agricultural areas are waiting for much needed rainfall, but it is
still at least two weeks away.
Throughout March and into the start of April there has been a
dominance of high pressure to the south of the continent. This has
hindered the passage of rain-bearing fronts and also led to the warmer
than usual conditions.
A weak front and trough are likely to move through SA on Wednesday and
Thursday next week, but are unlikely to bring much rainfall to the
Agricultural districts. A stronger front should arrive around Monday
14th April, but it also doesn't look too promising.
Despite this arid outlook, some hope is on the horizon for those
needing rain. Models are suggesting that rainfall should be near
average for the second half of autumn.
Moisture should increase towards the end of April over the nation's
tropics as the monsoon trough becomes more active. Some of this
moisture is likely to reach thirsty parts of SA with the aid of low
pressure troughs near the end of April or start of May.
