we wish to make it clear that the wider, more serious alleagtions including drug misuse and rape which are still being investigated are completely unrelated to mr danker. time for a look at the weather. here s chris fawkes. we have had some lovely sunshine already today, but arguably the best of the day s weather is behind us. these lovely guys in castleton, derbyshire, are increasingly becoming a thing of a past and we have very strong winds on the way, low pressure is finding itself at the heart of an atlanticjet low pressure is finding itself at the heart of an atlantic jet stream, pressure is falling quickly, over 30 malabar pressure is falling quickly, over 30 mala bar falls pressure is falling quickly, over 30 malabarfalls in pressure is falling quickly, over 30 malabar falls in the last 24 others and this low pressure is an example of what some people refer to as a weather bomb which will bring very strong winds tonight and tomorrow. this is a day of clouding over from the wes

when it gets the term a weather bomb, ere pressure becomes very stormy very quickly. the winds around that help push cold air widely. back to wednesday, calgary had its coldest december day in 26 years, 28 celsius. that cold air will sweep across canada and into a good part of central and eastern us. freezing anything which has fallen in terms of rain so flash freezing is a big issue but temperatures dropping by day and night. even in the south, texas and florida and the bahamas, some night temperatures could be 10 celsius. this is only part of the issue because with the weather bomb you get strong winds. we expect life threatening wind chill with temperatures as low as -70 chill with temperatures as low as 70 fahrenheit. five minutes will cost frostbite and there is no

of the jet stream at around 30,000 feet or so. a disturbance in the powerful jet stream forces the air aloft to accelerate away, removing air from the top of the column. the column weighs less and so the force it is exerting on the ground, the pressure gets lower. hence, low pressure. near the ground, air rushes in to replace what is lost higher up, and the area of low pressure rotates more and more quickly. and as the process continues, the storm is able to deepen explosively. on a weather chart, you will see more and more isobars appearing, like a dartboard, and if the pressure falls by at least 2a millibars in 2a hours, that is explosive cyclogenesis, or a weather bomb. weather bombs like storm eunice are not that unusual. but it is when explosive cyclogenesis happens near land that their impact can be extreme. eunice s winds were so strong they shredded part of the fabric roof of london s
