Met Office hour-by-hour weather forecast for London

Up to 50mm of rain is expected across southern England, including parts of south London, following the Met Office's issuance of a new yellow weather warning.

The warning is in effect until 12pm today (November 27), with the Met Office cautioning that periods of rain could lead to disruption throughout the morning.

This follows the impact of Storm Bert, which caused widespread flooding, turned roads into rivers, and brought winds exceeding 80mph.

Storm Conall, the third named storm of the season, has been named by the Dutch Weather Service in collaboration with the Met Office and Met Éireann in Ireland.
