Storm Eunice - 18th February

Oct 87 had winds of 115mph but it only affects a very narrow area and is difficult to predict -
Storm Eunice - 18th February
FetchCB replied to Thunder and Lightning's topic in Storms & Severe Weather
One element to factor in for urban areas is the venturi effect where the wind speed increases as it passes between buildings thus a 90mph gust could reach 115 - 120mph -
Storm Eunice - 18th February
FetchCB replied to Thunder and Lightning's topic in Storms & Severe Weather
I think the comments in regard to the fact that the storm hasn't even been formed yet and therefore subject to change in track and severity are, on the whole, accurate. What might be worth bearing in mind, however, is UKMet have invested significant effort following 1987 significant amount of research into not only the events of 1987 but also how to improve the forecast of these late developing storms. I would not be surprised if UKMO turns out to be the most accurate of all the models but not only that the interpretation of the models by the Chief Forecaster -

Assuming this is an ECM data set? If so I wonder how much of the ECM's tendency to overstate longevity of High Pressure is replicated? EDIT : seems its an amalgamation Seasonal forecasts | Copernicus CLIMATE.COPERNICUS.EU -

FetchCB replied to damianslaw's topic in Spring Weather Discussion
Thing is GW is not an entity as say temperature is. GW doesn't override anything its merely a name given to a set of observations. By way of explanation it is said that sea ice is retreating because of global warming. It is higher temperatures that cause the reduction in sea ice and temperature is already included in the forecasts. As a caveat to my statement above I would say that GW is possibly factored into climate modelling by the Hadley Centre by way of assumptions to understand the impacts of different scenarios -

Model discussion - hunt for cold - Christmas countdown
FetchCB replied to Paul's topic in Forecast Model Discussion
Actually it is especially in weather forecasting because the initial conditions are not known to enough accuracy to facilitate an accurate forecast(dependent on your definition of accurate, of course). You cannot say with any certainty that any forecast is right or wrong until that time has passed and then its hindcasting -
Worth bearing in mind that a significant population live away from the coast at elevation eg Consett which at 600m asl will most likely have blizzards and to all intents and purposes become cut off. If the power fails due to iced power cables it may well be a while before emergency services could get to them

Hurricane Ida
FetchCB replied to summer blizzard's topic in Hurricanes, Cyclones and Extreme weather worldwide
I suspect that Katrina is very much on their minds.. Storm surge 11-15 ft (Katrina was 18-20)...cat 4 on landfall The damage to Biloxi was catastrophic https://www.google.com/url?sa=t&source=web&rct=j&url=https://m.youtube.com/watch%3Fv%3DxTL4g8eK5rA&ved=2ahUKEwj8iZPPjNPyAhXBnVwKHYIKCFUQxa8BegQICRAF&usg=AOvVaw2et_j9v8741DloxPzq_I5Q I watched a documentary last night on Katrina. In Biloxi it showed a three storey concrete apartment block.... Except previously there were two of them.- 270 replies

Heat Health Warning a joint venture with Public Health England. Depending on level issued health bodies including NHS trusts are legally bound to enact certain protocols around management of resources. It is about the effects on health of heat (similar to the cold weather alert on the effects of cold) The extreme heat however encompasses far greater risks such as infrastructure etc and so will be used by rail authorities, local councils.

FetchCB replied to damianslaw's topic in Spring Weather Discussion
I think the heat health warnings assess impacts on the health sector,whereas the extreme heat warning seems to assess a greater range of impacts such as more people being at the coast. Such warnings allow local authorities to put contingencies in place officially. I think getting people caught up in the term extreme can be deceiving. I'm sat here in Cornwall 5 miles from the North Coast at 5pm with it feeling distinctly Mediterranean.. I don't recall that happening too often. -

Probably reflecting the ongoing climate change Why the Met Office is launching a new extreme heat warning | Official blog of the Met Office news team BLOG.METOFFICE.GOV.UK Although hot weather can often be seen as ‘good news’ and is enjoyed by many, it can have serious consequences. Research shows that, as a result of climate change, we... Like so many warnings issued by Met Office this will have mutli agency impacts and allow formal action to be undertaken by those agencies(mostly health, I suspect) in preparation for the heat -

FetchCB replied to Blessed Weather's topic in Regional
Funnily enough the met office app (yes I know) has us having heavy snow overnight and into tomorrow morning The fax charts have convergence zones in and around the Wash and I'm wondering if that is what is forming off the coast of North Norfolk. As the temps drop inland that feature could penetrate further inland. Of course now that has been signalled by the Met Office app it won't happen -

I've just noticed that the reason for the yellow warning update from 45 mins ago aside from extending the warning period to end of Wednesday was to drop ice as being the primary hazard in favour of snow
