Met Office Issues Yellow Weather Warning – Rain

Issued at: 12:04 on Tuesday 15 July 2014

Valid from: 03:00 on Saturday 19 July 2014

Valid to: 23:55 on Saturday 19 July 2014

Areas of heavy, thundery showers may develop over England and Wales from early on Saturday before moving northwards during the day. The development of these is uncertain but where they do form some torrential downpours are possible with frequent lightning, hail and locally strong gusts. Significant flooding is possible where these do occur from surface water as well as small, fast responding watercourses. The frequent lightning, hail and strong gusts could also be an additional hazard.

The public should be aware of the risk of disruption from any of these elements. This alert is likely to be updated in the coming days.

Chief Forecaster’s Assessment

Following a build of very warm and humid air from mid-week onwards there is the potential for the development of large thunderstorms over England and Wales from early on Saturday. In this situation large amounts of energy are available in the atmosphere and this coupled with high moisture content can lead to torrential downpours along with frequent lightning activity, hail and locally strong gusts. In this situation many elements need to come together at the same time to form these thunderstorms and so there remains large uncertainty in their development. This alert is therefore likely to be updated in the coming days.
