A HALO around the moon on Monday night had residents making dire weather predictions, but Rockhampton Bureau of Meteorology duty observer Brendan Bradford said the optical phenomenon wasn't a harbinger of doom.
"There was high cloud on Monday night, and when you get the moon appearing behind a high cloud you can get the halo effect," Mr Bradford said.
"It's caused by moonlight shining through ice crystals in cirrostratus clouds.
"Sometimes you can see it by day around the sun."
Halos can also form around artificial lights in very cold weather when ice crystals called diamond dust are floating in the nearby air.
According to lunar weather lore, a halo around the moon means bad weather is coming.
Mr Bradford said high winds could bring rain to Gladstone and along the coast, but there was not much heavy rainfall expected.
"There's a chance for showers on Friday and Saturday too," he said.
We've had high winds today and they will continue for most of today.
The phenomenon was visible all over Queensland from Rockhampton to the Gold Coast.
