Dry surge affecting tropics
The dry season is underway in the tropics and at the moment Northern Territory's Top End and tropical Queensland are seeing a dry surge. Gusty southeasterly winds are affecting the region leading to cool nights and dry days.
On Saturday in Queensland south easterly wind gusts of up to 40km/h were recorded at Cooktown and up to 61km/h at Burketown Airport in the Gulf of Carpentaria. In the Northern Territory Darwin saw gusts up to 41km/h and in Arnhem Land gusts of up to 44km/h were recorded at Maningrida Airport. These type of winds look to stick around for the remainder of the week and have prompted the Bureau of Meteorology to issue a strong wind warning for some coastal areas of the Top End and Tropical Queensland.
This southeasterly surge has led to some cold mornings, especially with wind chill causing it to feel colder. Burketown saw minimum temperatures of about 15 degrees on both Saturday and Sunday, about three degrees colder than average.Factor in wind chill and it has been feeling a few degrees colder.
This weather pattern is not unusual for the tropics at this time of year, and is in fact associated with the rainy and windy conditions experienced by southern states over the previous few days. An intense low pressure system over the Tasman Sea has combined with a high pressure system centred over the Great Australian Bight to send dry and gusty southeasterly winds up to northern Australia.
