Storm Dennis: Terrifying satellite image shows cyclone barrelling towards UK | Weather | News

BBC Meteorologist Derek Brockway posted the chart to Twitter, writing: “Storm Dennis is over the Atlantic undergoing rapid cyclogenesis as it turns north towards Iceland.

“It is forecast to have a central pressure of 922mb by midday Saturday.

“The lowest ever pressure recorded in the north Atlantic is 914mb on 11/1/1993.”

In certain circumstances, the central pressure inside an area of low pressure can fall at a very rapid rate.

These are known as ‘bombs’ and violent winds can develop around the system.

The resulting winds peak over a period of a few hours and can be strong enough to bring down trees and cause structural damage.
