Partly cloudy to cloudy skies, particularly in the morning, will prevail.

During the winter months, the storm track over the North Pacific is typically enhanced. Around ten tropical cyclones occur in the Australian region every season, and about four of those usually make landfall.

Copyright © 2010–2020, The Conversation US, Inc. It's typically associated with higher than normal tropical cyclone numbers in the Australian region. During La Niña events, the first tropical cyclone to make landfall also tends to occur earlier in the season. By using our site, you acknowledge that you have read and understand our Privacy Policy Tropical cyclone Nina developed in the Gulf of Carpentaria prior to Christmas and crossed the Cape York coast south of Weipa on Christmas day. "Come peak hurricane season in September, the prevailing tropical storm tracks increase across the Gulf of Mexico and the Caribbean, in addition to storm formation originating off the coast of Africa. The highly irregular oscillation of ENSO between El Nino and La Nina alters weather patterns around the globe and is directly correlated to tropical cyclone activity in the Atlantic and North Pacific. "We have never had two hurricanes in the Gulf of Mexico simultaneously.". Cyclone Tracy, which wiped out much of Darwin in 1974, killing 71 people, also occurred during an intense La Nina cycle as did tropical Cyclone Larry in 2006. Tropical formation is more favored in the Western Pacific and Atlantic, while somewhat suppressed in the Eastern Pacific. During La Niña years in Asia, the formation of tropical cyclones, along with the subtropical ridge position, shifts westward across the western Pacific Ocean, which increases the landfall threat in China. As we've seen most recently with Tropical Storm Sally in the US, tropical cyclones can cause massive damage over vast areas. But with monthly guidance up to four months before the start of the season, our new model, TCO-AU, is unmatched in lead time. Australian tropical cyclone behavior is largely driven by the El Niño-Southern Oscillation (ENSO)—a global climate phenomenon that changes ocean and atmospheric circulation.
