SCATTERED thunderstorms could hit Surrey and Hampshire overnight on Tuesday into Wednesday, the Met Office has warned.
A severe weather warning has been issued for the London & South East England region, valid between 5pm on Tuesday and 8pm Wednesday.
Thundery showers are expected to push north across southern parts of the UK through Tuesday evening, perhaps turning more widespread towards midnight.
Although many places won’t see these showers, there is a chance of localised flooding of homes, businesses and susceptible roads.
Frequent lightning may be an additional hazard with potential disruption to power networks. Similarly, but very locally, hail may cause impacts.
A spokesman for the Met Office said: “There is relatively low confidence in the areas more at risk of intense downpours. Some places will miss them altogether but where they do occur, there is the potential for locally 20 to 30 mm of rain within an hour.
“This may result in surface water flooding, particularly should these amounts fall across urban areas.”
