For people in parts of Lower Western and Upper Western Forecast Districts.

Issued at 10:57 am Tuesday, 24 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 south of the low is forecast to deepen today, increasing the risk of heavy falls.

HEAVY RAINFALL which may lead to FLASH FLOODING is forecast about parts of the Upper Western and Lower Western districts today and into Wednesday. Six hour rainfall totals between 30 and 60 mm are likely. 24 hour 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 today, becoming less likely by Wednesday afternoon. Isolated six hour rainfall totals of around 100 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 parts of western New South Wales into Thursday.

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.

121mm was recorded at Winnathee (near the SA border) in the 24 hours to 9am this morning, mostly falling in 6 hours during Monday.
