Severe Tropical Cyclone Debbie

Debbie was founded in Aravara Sea on December 18 within 250 km from the northern coast of Australia. Debbie tracked the southwestern part and strengthened the strength of strong tropical cyclones at the beginning of December 20. On the afternoon of December 20, Debbie moved to the south orbit slightly and began to weaken slightly, then overnight the Northern Territory coast between Gulben Island and Manning Rida. Debbies rained on the morning of 21 December and continued moving south to the land while continuing to move southwest within a few days after that.

Tropical cyclones were formed on the monsoon trough on December 16, and the MJO pulse spread to that area. Under the influence of low and medium east air speed, slow speed slowly moves west. Dongfeng Rapids, coupled with a decline in the upper classes, has made favorable conditions for the slow development of the low position while proceeding westward. As the impact of the monsoon's west wind increased on December 18, the low speed began to decelerate and began to move southwest. Debbie reached the intensity of the hurricane on December 18 and kept tracking the southwest. Just before the landing, Debbie began to weaken due to the upper limit. Debbie may continue to accompany dry air before landing due to weak vertical wind shear influence. Debbie crossed the coast of northern Australia on the evening of 20th December, and weakened to rain early December 21.

When Debbie crossed coastal regions with low population density, there was no major structural damage in the town. The community of Warruwi (Goulburn Island) and Maningrida suffered minor structural damage like a high roof steel panel. Walwi caused tree damage to the transmission line and due to Debbie's landing, power and water were interrupted. The area exposed to the center of Mayuzumi suffers serious vegetation damage, and 30% to 40% of the area tree is cut down. When the rain moved to the highest point in the Northern Territory in the northwest and eventually entered the Kimberley region of Western Australia, the river level rose sharply due to heavy rain and localized flooding occurred in many areas . On December 22, Charles Point near Darwin received 197 mm while Tinda near Katherine received 284 mm on December 23. The roads of the Karen River and the Waterhouse River were harvested due to floods

The strong tropical depression in 2017 is Australia's strongest tropical depression since Quang 2015 and since the year 2011 Isaiah it is considered to be the most dangerous low pressure in Queensland. Tropical cold was formed on March 23, and its low temperature gradually deteriorated the tropical cyclone named on March 26. After stabilizing and strengthening offshore to the Category 4 system, Debbie finally landed near Airy beach at 12:40 on March 28th. Later, Debbie quickly weakened to tropical cyclones late late March 28, but continued to move south, causing serious damage and floods in densely populated areas of southeastern Queensland and northern rivers It was. Overall, this storm caused Australia's loss of A $ 3.5 billion (US $ 2.67 billion) and the death of 14 people. This is mainly due to extreme floods. Since the 1991 Cyclone Fifi, this makes Debbie the most deadly hurricane.

On March 29, tropical cyclones are downgraded to tropical cyclones and are expected to move south to Central Queensland. The former tropical cyclone continues to cause strong winds and heavy rains on the central coast and the Whitsunday Islands, Central Highlands and coal fields. The risk of flood still exists.
