The State Emergency Service advises that people should:
* Keep clear of creeks and storm drains.
* Don't walk, ride your bike or drive through flood water.
* If you are trapped by flash flooding, seek refuge in the highest available place and ring 000 if you need rescue.
* Be aware that run-off from rainfall in fire affected areas may behave differently and be more rapid. It may also contain debris such as ash, soil, trees and rocks.
* After bushfires, heavy rain and the loss of foliage can make the ground soft and heavy, leading to a greater chance of landslides.
* Unplug computers and appliances.
* Avoid using the phone during the storm.
* Stay indoors away from windows, and keep children and pets indoors as well.
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
* For emergency help in floods and storms, ring the SES (NSW and ACT) on 132 500.
The next warning is due to be issued by 2:10 am Monday.

ENSO status: La Niña Watch. IOD status: Neutral. SAM status: Negative. Trending slightly negative. The El Niño Southern Oscillation (ENSO) is in a La Niña Watch, meaning there is approximately a 50% chance of a La Niña developing this year. Overall, models are now starting to look more like La Niña, with more widespread ocean cooling occurring in the South Pacific, helped by the consistently strong trade winds. While these are good signs that La Niña is starting to develop, a declaration would likely happen no earlier than November, meaning this is more likely to be a late and weaker event if it does eventuate. A La Niña typically increases rainfall over northern and southeastern Australia during spring, but has little effect for southwestern WA. The Indian Ocean Dipole (IOD) is in a neutral phase and is now unlikely to develop into either phase this spring. Conditions are closer to a negative IOD at the moment, so there may be some minor increases in the frequency of northwest cloudbands impactingAustralia. A neutral IOD tends to bring a small increase in spring rainfall for southwest WA, but has little effect elsewhere. The Southern Annular Mode (SAM) is in a negative phase, continuing on from the initial sudden Stratospheric Warming (SW) events over Antarctica since mid-July. These events increase the chances of negative SAM events, but are having a lesser effect moving forward in October. A negative SAM increases the frequency of cold fronts. During spring, this increases rainfall over western Tas and southern Vic, but decreases rainfall over eastern Australia. Rainfall outlooks are showing close to average for most of the country during October, with a higher chance of above average rainfall for northern and eastern Australia, increasing further into November and December. Models are also hinting that rainfall is more likely to arrive in the form of showers and thunderstorms, rather than broad rainbands, meaning rainfall in practice will likely be hit-and-miss for most of Australia thisspring.
