Expected Conditions
An extremely humid airmass associated with a slow-moving tropical low over the southern Northern Territory is driving the event. A trough extending south of this low is bringing the risk of heavy falls to northwestern NSW. Forecasters expect six-hour rainfall totals between 30 mm and 70 mm. These conditions may lead to dangerous flash flooding. Flood watches and warnings are currently active for the region.
Timeline
The risk of heavy rainfall is expected to persist through the remainder of Wednesday and into Thursday morning. Conditions are forecast to begin easing across the warning area from the middle of the day on Thursday as the weather feature weakens.
