There might be occasions when a Flood Warning is issued without it being preceded by a Flood Watch, largely because of the complexities of forecasting rainfall accurately. Weather fashions are excellent at identifying broader scale weather patterns but are not always capable of characterize the smaller scale options that may cause heavy rainfall, particularly in tropical areas.

Floods occurring all over Australia, nonetheless various kinds of floods are widespread in numerous areas.

Water Observations from Space is an internet service displaying historical surface water observations derived from satellite imagery for all of Australia from 1987 to current day. WOfS goals is to permit better understanding of the place water is normally current; the place it’s seldom noticed; and where inundation of the floor has been occasionally observed by satellite. WOfS shows the detected floor water from the Australia-extensive Landsat 5 and Landsat 7 satellite tv for pc imagery archive.
