Met Office Warnings Issued For: Greater London

  1. Yellow warning of rain

    From:
    1600 on Sun 30 August
    To:
    2350 on Sun 30 August
    Updated 30 August at 06:55 Active

    Warning

    Although not all areas will be affected, thundery showers are likely to affect some southeastern parts of England later on Sunday. Lightning may be an additional hazard.

    The public should be aware of the risk of localised impacts from heavy rain and flooding, which may affect travel and some outdoor events.This is an update to the warning issued on Saturday, to reduce the area at risk from the thundery downpours whilst delaying the start time.

  2. Yellow warning of rain

    From:
    0100 on Mon 31 August
    To:
    1700 on Mon 31 August
    Updated 30 August at 11:29

    Warning

    Further areas of heavy rain or thundery showers are likely to affect parts of southeastern England and East Anglia at times on Bank Holiday Monday. The main risk periods would seem to be before dawn and again during the middle of the day and into the afternoon. The evening should see a slow transition to drier conditions from the west.

    This update slightly reduces the northwestern extent of the area at risk from thundery downpours, and brings forward the end time of the warning. Given continuing complexities, a further update to the Warning is likely to be issued early on Monday.The public should be aware of the risk of further localised flooding and impacts on holiday activities.

A list of all UK Warnings can be found on our More UK Weather page.
