Met Office gives exact time thunderstorms will hit Bristol before 11-hour weather warning

The Met Office has predicted the exact time thunderstorms are set to hit Bristol ahead of an 11-hour weather warning this weekend. As of 7am on Sunday 17 September, the forecaster has issued a yellow warning for thunder and lightning, with heavy rain expected across the south-west and parts of Wales.

Local residents have been warned of the possibility of flooding and deep, fast-flowing water that could cause a “life risk”, with difficult and potentially dangerous driving conditions on roads in the area. Some communities may be isolated by flooded roads, while others may face power outages and loss of services.

The warning is in effect from 7am on Sunday to 6pm that afternoon. Involving most of the south-west, from Penzance to parts of Gloucestershire, Bristol is also expected to experience heavy rain and thunder in the early afternoon.

From around 12pm, Bristol residents can start to expect rain, which is likely to get heavier as the day progresses. By 2pm the worst of the weather will begin as the forecaster predicts a huge deluge coming from Devon. As the rain becomes stronger, thunderstorms are likely to begin from around 4pm, according to the Met Office.

According to forecasters’ expectations, the storm will hit the city between 4 p.m. and 5 p.m., before calming down for several hours. As rain continues, more storms are expected between 10pm and 12am on Monday (September 18). More rain is expected next week.

Deputy Chief Meteorologist Rebecca Sherwin said: “The most noticeable change in our weather is taking place through Saturday evening with increasingly humid air moving in from the south bringing thunderstorms and heavy rain. These heavy showers and thunderstorms will spread across much of the UK during Sunday with no place immune from the chance of seeing them.

“Some heavy rain may lead to impacts on the transport network, and with thunderstorms possible in some places, temporary power outages are possible. There is also a risk of hail and strong winds in some places. Severe weather warnings will likely be issued.” With increased confidence in areas likely to be affected.
