Tropical Cyclone Alessia underwhelms Top End

Jamie-Louise Morrison, Monday November 25, 2013 - 14:12 EDT

Recorded observations have shown Cyclone Alessia to have brought little out of the ordinary for Top End as it crossed land last night.

Last Thursday, a tropical low pressure system began to develop within the monsoon trough located off the north coast of Western Australia. This system slowly approached the border between Western Australia and the Northern Territory, as it developed into a Category One cyclone called "Alessia" on Saturday. The cyclone made landfall in the Top End around 9pm CST on Sunday, where it weakened to a low.

Many would have expected this system, once overhead, to bring some wild weather to the Northern Territory, yet it brought nothing too unusual. The ex-Tropical Cyclone "Alessia" saw Darwin receiving a mere 14mm of rainfall up to 9am this morning, which is not a lot when compared to the 104.8mm Darwin received earlier this month as a result of thunderstorms.

The system ended up bringing more rainfall ahead of it than when it touched landfall, with 58.4mm of rainfall recorded up to 9am in Darwin on Sunday (44.4mm more than 9am today). Daly Waters also received 8mm on the day prior to its approach, but only 0.2mm of rain had fallen up to 9am today.

Severe weather warnings were issued for damaging winds and heavy rainfall for the Darwin-Daly District north of Pine Creek, but they were later cancelled at 5am CST today. Wind gusts reached a maximum of 61km/h as the ex-Tropical Cyclone hit Darwin, two kilometres short of gale force winds.

The onset of the tropical low did see to the majority of places in the Top End experience their coolest day this month, with Tindal only reaching a maximum of 29 degrees on Sunday, eight degrees below Saturday's maximum temperature.

There is no cyclone expected to affect the Northern Territory within the next few days, aiding to calmer weather for the Top End however thunderstorms will remain likely.
