Severe Weather Warning
for Heavy, Locally Intense Rainfall
for Upper Western and parts of Lower Western Forecast Districts.
Issued at 4:41 pm Monday, 23 February 2026.
HEAVY TO LOCALLY INTENSE RAINFALL IN THE NORTHWEST.
Weather Situation
An extremely humid airmass lies over central Australia, focused around a slow-moving tropical low over the southern Northern Territory. A trough extending into the northwest of NSW is forecast to deepen on Tuesday, increasing the risk of heavy falls.
HEAVY, LOCALLY INTENSE RAINFALL for the following areas:
Lower Western and Upper Western
HEAVY RAINFALL which may lead to FLASH FLOODING is forecast about parts of the Upper Western district today, spreading to parts of the Lower Western district during Tuesday. Six-hourly rainfall totals between 30 and 60 mm are likely. 24-hourly rainfall totals between 50 and 90 mm are likely, with isolated totals to 130 mm possible.
Locally INTENSE RAINFALL which may lead to DANGEROUS AND LIFE-THREATENING FLASH FLOODING is also possible with isolated thunderstorms, more likely near the SA border. Isolated six-hourly rainfall totals of around 90 mm are possible.
There remains uncertainty around the location of the heaviest falls, as well as the future movement and strength of the low pressure system that is driving this weather. Periods of heavy rainfall may affect western New South Wales until the middle of the week.
Flood Watches and Warnings are current for the area. Please refer to https://www.bom.gov.au/weather-and-climate/warnings-and-alerts/ for more information.
Locations which may be affected include Tibooburra, Broken Hill, Wilcannia, White Cliffs, Wanaaring and Menindee.
88MM WAS RECORDED AT WINNATHEE (NEAR THE SA BORDER) IN THE 6 HOURS TO 4:15PM.

* 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.
