The UK Met Office has issued an amber weather warning for severe thunderstorms across eastern and south-eastern England, effective from 8:00 PM Thursday to 5:00 AM Friday (BST). The warning stretches from Eastbourne in Sussex up to Cromer in North Norfolk, placing millions on high alert for flash flooding, power outages, and major travel disruptions.

Dangerous Conditions Expected
The amber warning has been triggered by the forecast of intense storms, with rainfall totals between 30 to 50 mm, gusts over 40–50 mph, and frequent lightning strikes. The Met Office warns of potential life-threatening flash flooding and damage to property and infrastructure.
Adding to the urgency is the unusual timing of the storms, which may follow what could be the hottest day of the year. Temperatures in places like Norwich are expected to reach up to 30°C (86°F)—possibly surpassing the previous 2025 record of 29.3°C recorded in London on May 1.
The combination of extreme heat, rising humidity, and a looming cold front creates a volatile mix—primed for powerful thunderstorm activity.
Public Safety Measures Urged
Authorities are urging residents to take precautionary steps:
- Avoid travel during the warning period. Roads may flood rapidly, and visibility can become dangerously poor.
- Secure outdoor items and clear drains and gutters to prevent water accumulation.
- Stay indoors during peak storm hours and avoid open spaces or tall structures where lightning could strike.
- Check on vulnerable neighbors or family members, particularly those who may need help accessing food, water, or medical supplies.
Additional Yellow Warnings Across the UK
Alongside the amber alert, yellow warnings for thunderstorms have been issued across other parts of the UK:
- Southwest England and Wales: Friday, 2:00 PM – 11:59 PM
- Eastern & South-Eastern England: Friday, 7:00 PM – Saturday, 6:00 PM
- Wales, Western and Northern England, and parts of Scotland: Saturday, 12:00 AM – 6:00 PM
These storms are expected to be more scattered but could still bring localized flooding, lightning, and high winds.
From Heatwave to Downpour: A Rapid Shift in Weather
As the storms move in, temperatures will plunge sharply on Saturday. Highs in eastern England will likely drop to the mid-teens, while northern and western regions may settle into the upper teens. This dramatic cooldown marks the end of a short-lived heatwave and the beginning of a cooler, wetter weekend.
Meteorologists note that this rapid transition—from scorching heat to flooding rain—is characteristic of unstable summer weather patterns in the UK.
Impact on Travel and Services
Transport services are bracing for significant delays:
- Trains and buses may face cancellations or altered schedules due to flooding or debris on tracks and roads.
- Motorists are advised to avoid flood-prone routes and to never attempt to drive through standing water, which may be deeper and more dangerous than it appears.
Stay Updated and Stay Safe
The Met Office continues to update its alerts and has published detailed storm safety guidance, including how to prepare homes, travel safely, and protect vulnerable individuals. Authorities stress that even shallow floodwater can be dangerous, and lightning poses serious risks during these events.
As Britain braces for another bout of unpredictable weather, the public is reminded to:
- Monitor live weather alerts
- Follow local authority advice
- Remain cautious and vigilant
Closing Note
This amber alert serves as a stark reminder of how quickly British weather can shift from balmy to brutal. As residents across eastern and southeastern England prepare for potential chaos, taking the right precautions today could help save lives and reduce the impact of tomorrow’s storm.
