A spell of heavy rain is set to batter Southampton as summer comes to a close.

The Met Office issued a 12-hour yellow weather warning for rain from 9pm tomorrow to 9am on Thursday.

There is a small chance that homes and businesses could be flooded quickly, according to the warning, with damage to some buildings from floodwater, lightning strikes, hail or strong winds.

Here’s what to expect

  • Spray and sudden flooding could lead to difficult driving conditions and some road closures
  • Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
  • There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost
  • There is a small chance of fast flowing or deep floodwater causing danger to life

A spokesperson from the Met Office said: “Scattered heavy showers on Wednesday evening may merge into longer spells of heavy, showery rain in places through Wednesday night into Thursday morning.

“Where heavy downpours occur, perhaps thundery in places, accumulations of 20-40 mm are possible in an hour or two, with the small chance of isolated accumulations over 50 mm, potentially impacting the Thursday morning commute in some areas.”
