Weather Warning: Heavy showers are likely with a small chance of flooding

Valid: 6am to 8pm on Tuesday 1st October

Heavy showers are likely to track across the region as we move through Tuesday. Some of these showers will band together forming some longer heavy spells of rain.

Torrential downpours are likely which may lead to some localised flooding as rain is already falling on saturated ground.

What to expect

  • Spray and flooding could lead to difficult driving conditions and some road closures
  • Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services
  • There is a small chance that homes and businesses could be flooded, causing damage to some buildings
  • There is a small chance of fast flowing or deep floodwater causing danger to life
  • There is a small chance that some communities become cut off by flooded roads
  • There is a slight chance of power cuts and loss of other services to some homes and businesses

The details

Heavy showers are expected to affect south Wales and southwest England on Tuesday morning then other parts of southern England during the day, peaking across the southeast during the afternoon. These will become slow-moving for a time with some very large rainfall totals possible in a few places. Whilst many places will see showers, the majority of places will see only relatively small rainfall accumulations. The highest rainfall accumulations are only likely to occur in a few spots where the showers become slow-moving, with 40-50 mm possible in only a couple of hours.

Lightning and some hail may also prove additional hazards for one or two locations. The showers will clear from the west and the north later in the afternoon but persist in the southeast into the evening.
