Weather forecasters are warning that cold, stormy weather will hit Britain in the coming days.
High winds, rain and even frost are predicted across the country, and temperatures could fall to as low as zero, the Met Office has warned.
The Met Office has issued severe weather warnings for most of northern England and Scotland, as gusts of up to 50mph are expected.
Coastal areas have been put on alert for "large waves" and meteorologists have warned of travel chaos as transport links could be hit by disruption.
Chief forecaster Eddy Carroll said: "While such wind gusts would not be unusual in the autumn and winter, they are likely to pose a few more problems coming in the summer holiday period, especially for those engaged in outdoor activities such as sailing or hill walking.
"Some minor disruption to transport is possible, for example delays to ferries, bridge restrictions and perhaps minor damage to trees."
The warnings are in place for Monday, but the bad weather is set to continue into the rest of the week.
Temperatures are also set to fall well below the average for August, and forecasters say there is the possibility of frost during the week in some parts of Scotland.
Calum Maccoll, a Met Office spokesman, said there is a "very autumnal" and "unseasonably cool" feel to the conditions in northern areas. "You could see grass frost towards dawn," he added.
