For people in parts of Upper Western Forecast District.

Issued at 12:55 pm Sunday, 22 February 2026.

Heavy rainfall developing about the northwest from early Monday morning.

Weather Situation: An extremely humid airmass lies over central Australia, focused around a low over the southern Northern Territory. An approaching front and upper trough will interact with this airmass to generate areas of heavy rainfall about northwestern New South Wales from Monday morning.

HEAVY RAINFALL which may load to FLASH FLOODING is forecast about parts of the Upper Western district from the early hours of Monday morning. Six-hourly rainfall totals between 30 and 60 mm are likely. 24-hourly rainfall totals between 50 and 80 mm are likely, with isolated totals to 100 mm possible.

There remains uncertainty around the future movement and strength of the low pressure system over central Australia 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.
