FLOOD THREAT ADVICE/Alice Springs District

Issued by the BUREAU OF METEOROLOGY, DARWIN
at 1038 CST Monday 21 DECEMBER 2009

AREA INVOLVED
Alice Springs District.

RAINFALL SUMMARY
It is currently fine and dry over the Alice Springs district.

WEATHER SUMMARY
Severe Tropical Cyclone "Laurence" off the eastern Pilbara coast is expected to
make landfall in the next day or two. After moving inland, Severe Tropical
Cyclone "Laurence" is expected to only gradually weaken, reaching the southwest
Alice Springs District late Wednesday as a deep tropical low. There is the
potential for widespread moderate falls over much of the Alice Springs District
on Wednesday and Thursday. Dependent on the speed and direction of movement of
ex-Tropical Cyclone "Laurence", locally heavy falls and strong, squally winds
may also develop over the southwest Alice Springs District on Wednesday.

FORECAST for the rest of today and Tuesday
Storms extending down the western border of the Alice Springs district with
isolated falls 15-30mm expected.

OUTLOOK for Wednesday and Thursday
Widespread falls 50-100mm may develop over much of the Alice Springs District as
ex-Tropical Cyclone "Laurence" moves through the far southwest late Wednesday
and into South Australia on Thursday. Locally heavy falls to 150mm possible in
the far southwest near ex-Tropical Cyclone "Laurence". These may lead to
significant stream rises.
