They advised residents to secure outdoor items weighing less than 25kg and highlighting the ‘fantastic opportunity’ to feel weightless for the day.
The post said: "We have received information from the British Space Agency that a unique alignment of three planets will result in an upward gravitational pull making people and items lighter today.
“As a safety measure we advise public to tie down any items that are outside weighing less than 25kg, this will prevent any items inadvertently landing in the roads.
"The BSA have also informed us that this unique event will give people an opportunity to feel weightlessness, and invite our community to jump in the air throughout the day to experience a strange floating sensation that should last for about 4 seconds.
"An astrophysicist has said that this only happens once every 376 years, so don’t miss this fantastic opportunity to feel weightlessness in your own home”.
