The precipitation, which began on January 19, 2019, in the northeast of Queensland, has been effective over the region until 12 February 2019 by increasing its severity from time to time. The region is under the influence of the low- pressure center and the monsoon trough which occasionally reaches a pressure of 992 hPa. On January 27, 2019, the daily total precipitation values were maximized for the investigated rainfall period prolonged about the three weeks over the region. The maximum daily total precipitation values were measured 562.0 mm at Mossman Central Mill, 471.6 mm at Whyanbeel Valley, and 468.8 mm at Cape Tribulation Store Station. The water level reaches at 12.5 m of height at the Daintree River. Townsville is the most affected area by heavy rainfall. Thousands of people are rescued in the area, and thousands of houses are flooded. About 500,000 cattle dies in this flood. Total damage including infrastructure is about AUD $1.5 billion.
