Local authorities and transport operators have issued warnings urging the public to exercise caution and to prepare for possible flooding in low-lying and coastal areas. This information was widely covered by reporters from national outlets highlighting the keen interest among weekend travellers.

What Are the Specific Forecast Details from the Met Office?

The latest forecast details provided by the Met Office indicate that London is expected to experience light rain at around 11 °C, which feels closer to 9 °C due to the damp conditions and wind chill factor. Rain chances are very high, at 95 percent or more, stretching into the late morning. Though rainfall is predicted to ease by the afternoon, weather forecasters cautioned that scattered showers could return during the evening hours.
