What This Map Covers

Map viewport is centred on London, England, and takes in the surrounding region. It shows lightning flashes detected from space by the EUMETSAT Meteosat Third Generation Lightning Imager, a few minutes after each flash. Greater London and the Thames Valley see frequent summer thunderstorm activity, with warm plumes crossing the Channel from France and Spain setting off lightning quickly.

This is satellite optical lightning detection: it records total lightning as flashes, does not separate cloud-to-ground strikes from in-cloud flashes, and places each flash approximately rather than to the metre. It is not rainfall radar, not a forecast and not a complete storm archive. Thick cloud and processing conditions can cause flashes to be missed. This is not a Met Office product and carries no official warning status.

Safety limit: absence of a marker never proves outdoor safety. Satellite detections can be delayed or missed, and storms move between refreshes.

LIGHTNING AROUND LONDON

What thunderstorms near London usually look like

London's biggest thunderstorms are rarely made in London. They usually form over France or the Channel in warm, humid air and cross the coast of Kent and Sussex before reaching the capital, which is why they so often arrive late at night or before dawn and why the map lights up to the south-east first. A second, more local pattern shows up on hot afternoons, when the built-up area adds its own heat and storms fire over the Chilterns, the North Downs or the Thames Valley and drift across the suburbs. Because this viewport reaches well beyond the M25, you can usually see a storm approaching from the Channel or from the west before it is audible in central London — useful if you are on the river, in a park or on a building site.

The map records flashes that have already happened, not a forecast. For official thunderstorm warnings in England, follow the Met Office.
