Severe Weather Alert: Ex-Tropical Cyclone Mitchell Hits WA - Flooding, Rainfall & Perth Forecast (2026)

Tropical Storm Alert: WA Braces for Impact

As ex-tropical cyclone Mitchell makes its way inland, parts of Western Australia are on high alert for severe weather conditions. But here's where it gets controversial: despite the cyclone's downgrade, its impact is still significant, and some regions are bearing the brunt of its fury.

Perth, the capital city, woke up to a damp and dreary morning as Mitchell crossed the coast. While the cyclone has weakened, its presence is still felt, with heavy rainfall and potential flash flooding predicted for certain areas.

Rainfall Records and Flood Warnings

Gascoyne Junction has already experienced an astonishing 132mm of rain since Monday morning, and Shark Bay Airport received a substantial 104.2mm in just 48 hours. Several sites in the Gascoyne region continue to face heavy downpours, with Pindarring Rocks recording an impressive 41.8mm in the past two hours alone.

A severe weather warning has been issued for the central Wheatbelt and Gascoyne and Central West regions, with rainfall between 25mm and 50mm expected. This could lead to flash floods, a serious concern for local communities.

Additionally, a minor flood warning has been issued for the Fitzroy River in the Kimberley region, and small river rises are expected along the Moore River.

Cyclone's Path and Impact

Ex-tropical cyclone Mitchell is moving in a south-easterly direction and is expected to weaken gradually, according to BOM meteorologist Grace Abbott. This means that while Perth and its metropolitan area will be spared the worst, other regions are still at risk.

"Perth is on the edge of a cloud band extending from Mitchell, which has brought some showers this morning. These are expected to clear gradually, but the humidity will remain high throughout the day. From tomorrow, we'll start to see a gradual drying out process," Abbott explained.

The metro area is predicted to return to its typical dry heat for the rest of the week, with sunny skies and temperatures ranging from 28 to 30°C.

And this is the part most people miss...

While the focus is often on the immediate impact of cyclones, the aftermath can be just as critical. The potential for flash flooding and river rises highlights the need for continued vigilance and preparedness. It's a reminder that even downgraded cyclones can have a significant impact on our communities.
