Weather Warnings


Valid: Sunday 8th July 2012

Issued For: Heavy Rain, Localised Thunderstorms

Highlights

  • Low Pressure moving Eastwards will stall across the South-East
  • Persistent Heavy Rainfall leading to localised flooding
  • CAPE in the region of 400 – 600 J/KG leading to localised thunderstorms

Forecast Detail

Through the course of Sunday the area of Low Pressure responsible for bringing the heavy rain and flooding across parts of the country during the last couple of days or so will edge Eastwards and slow across South-East England and this will lead to some persistent heavy rainfall, due to the already saturated ground and predicted high rainfall totals localised flooding is therefore likely to be an issue. Rainfall totals in excess of 30mm are expected with locally 40-50mm not being out of the question.

There will also be some weak CAPE and LIFT evident across the South-East extending across Central Southern England and up into the Midlands leading to localised thundery downpours.

Orange Zone – Weather Warning Issued

Through the course of Sunday slow moving, persistent heavy rainfall will push across the South-East of the country, rainfall totals in excess of 30mm are expected with local falls possibly being as high as 40mm+. This combined with saturated grounds brings the risk of localised flooding.

Yellow Zone – Weather Advisory Issued

Weak CAPE and LIFT combined with an advancing Low Pressure system is likely to generate slow moving, heavy thundery downpours. Whilst they will be fairly scattered high rainfall totals in a very short space of time is likely to lead to brief localised flooding. Totals in this area are expected to be around 2-6mm though will be higher in areas that see these heavy thundery showers.
