For people in parts of Southern Tablelands, South West Slopes, Riverina, Snowy Mountains and Australian Capital Territory Forecast Districts.

Issued at 1:10 pm Tuesday, 16 January 2024.

Weather Situation: A very humid airmass drawn from the tropics will move over southern New South Wales during Wednesday. This airmass will lift ahead of an approaching cold front from Wednesday morning, resulting in areas of rain with embedded heavy shower and thunderstorm activity.

HEAVY RAINFALL which may lead to FLASH FLOODING is forecast for parts of the Southern Tablelands, ACT, Snowy Mountains, Southwest Slopes and Riverina from late Wednesday morning. Six-hourly rainfall totals of 50 to 80 mm are likely, with 24-hourly totals of 80 to 120 mm possible.

Isolated areas of INTENSE RAINFALL which may lead to DANGEROUS AND LIFE THREATENING FLASH FLOODING may also occur with persistent heavy showers and thunderstorms, with six-hourly totals exceeding 100 mm possible. A separate Severe Thunderstorm Warning will be issued if intense rainfall is detected within the warning area.
Conditions are forecast to ease from the west during Wednesday night.

Locations which may be affected include Yass, Albury, Tumbarumba, Tumut, Khancoban and Holbrook.

The State Emergency Service advises that people should:
* Don't drive, ride or walk through flood water.
* Keep clear of creeks and storm drains.
* 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.
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
* For emergency help in floods and storms, ring your local SES Unit on 132 500.
