VIDEO: Teresa Mannion has delivered a last-minute warning to Santa
"Don't take risks on treacherous roofs."
Teresa Mannion is now a national treasure after that legendary weather report, so when she offers advice everyone listens.
This includes Santa himself, who received some cautionary wisdom from Ireland's favourite reporter, before he sets off tonight.
RTÉ posted this video on their Facebook page and it's brilliant.
Take it away, Teresa.
Santa is on his way... and Teresa Mannion has a very important message for the man in red!
