Heavy showers and thunderstorms late Sunday and into Monday may lead to some surface water flooding in places bringing, amongst other things, disruption to transport and difficult driving conditions.
Temperatures could reach up to 28C in Kent tomorrow (27 May), with temperatures staying at around 22C on Sunday (28 May) and bank holiday Monday (29 May).
But a yellow weather warning of rain has now been issued for Kent, which is valid from noon on Sunday 28 May until noon on bank holiday Monday.
Sunday will start fine and dry but cloud and showers are expected to move north during the afternoon and evening, becoming locally heavy with thunderstorms. There is the potential for some torrential downpours with some locations seeing 30 mm, possibly as much as 40 mm, in just an hour leading to surface water flooding in places. There could also be some river flooding in fast-responding urban catchments.
The Met Office has issued a Yellow RAIN Warning (Very Low Likelihood of Medium Impacts) to cover the potential risk from the heaviest downpours which could lead to surface water and isolated river flooding, disruption to transport and difficult driving conditions.
Lightning strikes are also possible, which could bring a chance of power cuts.
A Met Office spokesman said: "Another band of heavy rain is likely to spread northward through Sunday into Monday, with some locally torrential downpours and thunder possible.
"There are early indications that this could result in some disruption, with sudden flooding of roads, transport routes, homes and businesses possible. Please monitor forecasts through this weekend."
The Met Office currently predicts humid conditions in Kent, with rain set to fall in Kent on Sunday night and early Monday morning.
Updated warnings will be posted on the Met Office's website here.
