Heavy rainfall is expected across the northwest Kimberley from Friday into Saturday, accompanied by a risk of flash flooding along the coast and inland areas.

Gale‑force winds and heavy rainfall with potential flash flooding are forecast in the northwest Kimberley from Friday night, potentially affecting coastal and inland communities including Derby, Broome and nearby towns.

Travelers, visitors and tourists are advised to leave the warning area and stay informed via Emergency WA and official channels.

There is no immediate danger, but residents should begin preparing for dangerous weather and stay updated through Emergency WA and BOM advisories.

DFES is monitoring the situation and urges residents to prepare for dangerous weather, check updates, and follow official guidance.

Key preparations include securing outdoor items, stocking a five-to-seven day emergency kit with essentials, and ensuring all household members know the emergency plan.
