The Met Office has issued a second yellow weather warning for fog just hours after the first. The warning covers south east Wales and the forecaster warns there will be reduced visibility on Thursday evening and overnight due to heavy fog. The warning is in place from 4pm on Thursday, December 1 to 11am on Friday.
This warning comes just hours after an initial fog alert was issued to parts of wales for Thursday morning. The new warning reads: "Areas of fog are likely to reform and expand Thursday evening with large areas of poor visibility and some places seeing less than 100m visibility at times. The fog is likely to persist for many overnight but then clear from the east during Friday morning.
The Met Office warns that fog patches will cause difficult driving conditions and perhaps some travel disruption, including slower journey times with delays to bus and train services possible and a chance of delays or cancellations to flights.
