Storm Dennis warning: Pressure dropping to CATEGORY 5 HURRICANE level – Britain braced

Meteorologist Craig Ceecee made the shocking claim while responding to a satellite image of Storm Dennis shared on Twitter. The image showed the storm was expected to have a central presser level of 922mb by midday today. Mr Ceecee responded: “That is one incredible image. 914 mb is comparable to a category 5 hurricane, although the dynamics and gradients are completely different (lower winds in a much larger area).”

Category five is the most severe type of storm and means that winds can be up to 157 mph and can be known to even destroy houses and buildings.

Warnings have been issued for across the UK as the storm is expected to bring with it a month’s worth of rainfall.

Hundreds of flights have been cancelled as the country prepares for its worst floods of the year.

Army troops have reportedly been called in to aid residents of Calderdale in West Yorkshire as worry over intense flooding builds.

The Met Office has issued several National Severe Weather Warnings for wind and rain from Saturday to Monday, which include amber rain warnings for some of England and Wales.

Met Office Chief Meteorologist, Steve Willington, said: “Storm Dennis will bring another very unsettled spell of weather this weekend with a risk of flooding, particularly in parts of England and Wales and also southern Scotland, where snowmelt will add to the flood risk.

“Following Storm Ciara last weekend and further spells of rain this week, the ground is already saturated in places. With Storm Dennis bringing further heavy and persistent rain over the weekend, there is a risk of significant impacts from flooding, including damage to property and a danger to life from fast flowing floodwater.

“Our advice is to keep an eye on the latest weather forecast and weather warnings for your area and to follow the safety advice from officials.”

Caroline Douglass, Flood Duty Manager at the Environment Agency, said: “We are advising people to sign up for flood warnings by phone, text or email and to access the latest safety advice on gov.uk by searching ‘sign up for flood warnings’.

“Remember to never drive or walk through flood water, just 30cm of flowing water is enough to move your car – it’s not worth the risk.”

A low pressure area usually begins to form as air from two region collides and is forced upwards.

This rising air creates a vacuum effect.

The more violent the rising air near the centre is, the faster the air must rush in from the sides creating strong winds.
