Update expected from organisers at midday
TT organisers will give an update on today's qualifying schedule at lunchtime.
Practice is due to take place tonight, but with more rain expected today there's a warning the session could be disrupted.
An update will be issued at midday.
George Shimmin from Ronaldsway Met Office says conditions aren't forecast to be favourable:
Yellow weather warning for frost and icy patches
