We're being warned of gale force winds and heavy rain across Hertfordshire from lunchtime today.
The Met Office say the warning is in place until 9am on Saturday morning.
Forecasters say "An area of rain and strong to gale force winds is expected to cross much of southern England before clearing to the east on Saturday morning.
"There is a low likelihood that the system could be intense enough to bring disruptive wind and rain to some parts. The public should be aware of the potential for disruption particularly for those engaged in outdoor activities.
"An area of low pressure is expected to run northeastwards close to southern England clearing on Saturday.
"Whilst a wet and windy period is expected, particularly in southeast England, there remain large uncertainties in the track and intensity of this low pressure system.
"More than 20 mm is expected quite widely however, there is a low likelihood that this will be deeper bringing the potential for more than 60 mm of rain in some places as well as gusts of around 50 mph on coasts and 40 mph inland. Were this to occur some disruption, particularly to outdoor activities, would be likely as well as disruption to travel given the large volume of traffic on Friday afternoon."
