Major flooding likely as 36 hours of rain is expected for the UK!

The UK is currently experiencing the third named storm of the season, Storm Callum.

Strong winds have been felt across many parts today with Cairngorm Mountain seeing a wind gust of 116MPH earlier today!

Overall gusts of 50-70MPH have been more typical which will continue throughout today.

Whilst this may cause problems in one or two areas the main threat associated with Callum is the rain.

For 24-36hours we will see an almost stationary cold front alligned through Wales, The North West of England and into Scotland.

This will have the potential to drop 100-150mm of rain easily with some models suggesting up to 350mm of rain!

This of course will flow into the rivers and area prone to flooding need to follow all local guidance. 

Monsoon rains to continue & intensify this afternoon with flooding a concern for the Capital!

The wet weather is well and truly underway with things only set to get worse over the next 3-6hours.

In total as much as 80mm of rain could fall which to put in perspective the average for the entire month is just 48mm in London.

Currently there are 2 flood warnings and 5 flood alerts in place however with much of the rain still yet to fall these numbers are set to rise rapidly.

Way over a months worth of rain to fall tomorrow as Met Office issues a severe weather warning!

Enjoying the typical British summer?

Well things dont look like improving anytime soon with over a months worth of rain set to fall on Wednesday for London and the South East.

In total as much as 60 to 80mm will fall in places with rain pretty much constant from mid morning until around 9pm.

Thursday should bring much brighter prospects, with highs of around 20/21C.

However things are changing again at the end of the week when another band of rain moves in on Friday evening into Saturday.

See the full Met Office forecast below:

Between 00:05 Wed 9th and 23:55 Wed 9th

An area of heavy rain will sink slowly southwards across the east and southeast of England during Wednesday. Some transport routes may be affected by localised flooding leading to longer journey times. In addition, flooding of homes and businesses is possible. The heaviest of the rain should gradually become confined to the extreme southeast of the UK later in the day.

Chief Forecaster’s assessment

An area of showers will spread from the Irish Sea across Wales, and parts of southwest and south England on Tuesday. Whilst many areas will not see the heaviest of these, accumulations of 15-20 mm in an hour are possible along with 30 mm or so in 2 or 3 hours.

Thousands ordered to evacuate homes as Oroville Dam is close to collapse!

More than 180,000 people in northern California have been told to evacuate their homes after both overflow channels at the tallest dam in the US were found to be damaged.

The emergency spillway of the 770ft (230m) tall Oroville Dam was close to collapse, officials said.

The excess water has now stopped flowing.

However, late on Sunday, Butte County Sheriff Kory Honea said the evacuation orders remained in place.

Water levels in the reservoir have risen following heavy rain and snow after years of severe drought.

It is the first time that Lake Oroville, which lies 65 miles (105km) north of Sacramento, has experienced such an emergency in the dam’s near 50-year history.

In a statement posted on social media on Sunday afternoon, Mr Honea ordered residents to evacuate, repeating three times that it was “NOT a drill”.

The California Department of Water Resources warned that the emergency spillway next to the dam was “predicted to fail”.

Residents of Oroville, a town of 16,000 people, were told to head north.

There was gridlock on roads heading out of the town, with some evacuees complaining that they should have been given more warning.
