Major snowstorm paralyzes London

Heavy snow in London, England yesterday did something the Nazi Blitz could not--stop the city bus system. The heaviest snow in 18 years hit the city yesterday, when eight inches (20 cm) of snow blanketed the city. All five major airports in the region closed, all London city buses were pulled off the streets, and the subway system was nearly paralyzed by the snows. It was the heaviest snow since February 7, 1991, when 25 cm fell. In that storm, wind-driven snow drifts of up to three meters (ten feet) crippled road and rail networks across the country.

Heavy snows are rare in London, due to the moderating influence of the ocean waters that surround the British Isles. The prevailing winds from the west or northwest pass over these ocean waters, which are heated by the warm Gulf Stream Current. This makes rain the usual form of winter precipitation for London. Monday's snowstorm was made possible by a strong high pressure system over Scandinavia, whose clockwise flow pumped cold air from western Russia westward over the North Sea and into Britain. A trough of low pressure that formed in this cold air mass moved over Britain, bringing heavy snow. As the cold air accompanying the trough passed over the relatively warm waters of the North Sea, it picked up moisture and instability, enhancing the snows over England in a manner similar to Lake Effect snowstorms over the Great Lakes of North America. The instability of the air mass within Monday's snowstorm was so intense that several UK locations reported "thundersnow", a very rare occurrence in the British Isles. Monday's snow storm also caused traffic problems in France, Switzerland, and Spain. The storm spawned a possible EF2 tornado in southern Spain, as well.

This winter has been the coldest winter since 1996-1997 for England and Wales. Minimum temperatures were as much as 2°C below average in December in western portions of the UK. A cold air outbreak the first week of January brought some of the coldest temperatures seen in southern England since 1991.

I'll have a new post Wednesday or Thursday.

Rosenstiel School of Marine and Atmospheric Science is world class. The NHC and NOAA are down there so is Chris Lansea who I personally hold in very high regard. My family has been there on the marine biology side since 1948, helped make it world class. Ronsenstiel is where the action is if tropical weather is your interest..not many coconut palms, warm tropical breezes or South Beach in Oklahoma. JMHO.


Thanks I don't know where to find that info and I was really busy yesterday

Heavy snow's always been rare in London because of the urban heat effect. The surrounding counties used to have heavy snowfalls regularly - six inches and more was common. Mrs FA grew up in Kent, south east of London and remembers regularly having to walk home from school because the buses stopped running. This storm really made the headlines because since the 1970s/80s the typical temperature when the European high starts sending in the east winds has gone up from around freezing to 2/3 degrees above - makes all the difference.

Joint Typhoon Warning Center

Tropical Disturbance Summary (0600z 04FEB)
===========================================
An area of convection (95W) located at 5.2N 139.1E or 295 NM east-southeast of Palau (Koror). Recent animated infrared satellite imagery shows deep convection persisting along a convergent band on the northern periphery of a weak low level circulation center evident in a 2031z Quikscat Pass. This disturbance lies equatorward of an upper level anticyclone axis in an area of moderate easterly vertical wind shear. This vertical wind shear is expected to increase as the low level circulation center moves west over the next 24 hours, However strengthening low level westerly flow to the south of the low level circulation center may provide a means for slow development despite the increasing shear.

Maximum sustianed winds near the center is 10-15 knots with a minimum sea level pressure of 1006 MB. Because the low level circulation center is weak and vertical wind shear is unfavorably strong, the potential for this disturbance to form into a significant tropical cyclone within the next 24 hours is POOR.

oh my a northern hemisphere tropical disturbance, LOL

you said you recorded gusts to 96 MPH earlier

then it was blowing way above that, and you were still standing

what was the peak gust?


Look again at the hi-def footage. Right after I rescue the two people, I turn to go back out into the storm and almost slip. Look at my right hand pocket on my pants! You'll see the wind gauge coming out. Two seconds later, the hurricane ate it.

So I can't tell you for certain how fast the wind was, but again...look at the radar. I'm in the southern eyewall of the storm. You can see it goes hot red there. That's the part of the storm where I claim that Cat III conditions existed.

It's been argued I'm right. And it's been argued I'm wrong. But I was there. And you can see it. It was pretty intense!

I guess if someone really wants to know that bad how fast the wind was, they can analyze the video frame by frame and measure the distance traveled by the water jets being sprayed by the storm. Those are regular size bricks underneath my feet, so measuring distance to determine speed should be pretty easy.

I'm too lazy to do it, though. :)

ya those reflective suits are good be easy to spot ya if ya start bobbin around in the water


Correct. As you probably already know, one of my goals this year is to get caught up in a storm surge.

Dangerous? Oh yeah, very.

Crazy insane? For ordinary folk, yes, but I'll be outfitted with all the best safety stuff. It will be checked out at the community pool...in the deep end.

Money shot? You bet! :)

It's a really good and long story, but the short of it is that I once was a pretty good running back in football. All that balance training really took.

Hello everyone!

I got some cool news this week. There are two outfitters that are going to sponsor my hurricane hunting expeditions this coming year! They saw my Hurricane Dolly video in hi-def and agreed to send me their product line in exchange for the use of any video footage I get this year.

The first company to sponsor me was Frogg Toggs out of Alabama. They make the inclement weather gear I wore in Hurricane Dolly and Ike. The products they're sending me for use this year include reflective suits, so I can be easily spotted.

The second company to sponsor me was Bladerunner.tv...they're in England and produce high-quality, light weight kevlar undergarments and such.

I'm pretty excited about getting out there again if and when a hurricane dares come ashore.

I'm also glad to see that everyone is having fun in all this cold weather, no doubt caused by global warming! ;)

Peace, out!
