For people in parts of Pilbara, Gascoyne, North Interior and South Interior districts.

Issued at 10:53 am Tuesday, 17 May 2022.

Heavy rainfall to continue over parts of the Pilbara today, extending into the interior overnight.

Weather Situation: An upper trough deepens a slow-moving surface trough over northwestern WA, resulting in the formation of a cloudband with embedded thunderstorms. The trough and associated cloudband are forecast to weaken later on Wednesday.

HEAVY RAINFALL which may lead to FLASH FLOODING is forecast to continue over the Pilbara district, extending further inland during the day and overnight to reach adjacent western Interiors and the far northeastern Gascoyne. Six-hourly rainfall totals between 70 and 100 mm are likely for the Pilbara, with isolated totals around 120 mm possible about the coastal fringe. Further inland, six-hourly rainfall totals between 60 to 90 mm are likely.

While heavy falls are not uncommon through this area, they are unusual at this time of year and may cause damage to property and make road conditions hazardous.

A Flood Watch is current for parts of the Pilbara and Central Desert Areas. For more details, please visit www.bom.gov.au/wa/warnings.
