The main weather features to watch out for this weekend are:
- Scattered showers today turning wintry (soft hail/sleet/wet snow) at higher levels and perhaps also down to lower levels at times, more especially in inland Cumbria/Lancashire. Risk of slight accumulations mainly on higher Cumbria/Trans-Pennine passes but not considered ‘warnable’ at present.
- The next bout of rain/wind is expected late Friday afternoon/evening for which Wednesday’s Yellow Alert has been re-issued (valid 1500 Fri to 0300 Sat, medium likelihood of minor impacts) for an almost identical area (Cumbria and most of Lancashire). Today’s Flood Guidance Statement (see Hazard Manager) aligns with the Alert in having Cumbria and Lancashire at low flood risk on Fri/Sat from either/or river/surface water impacts.
- Remaining unsettled right up to and beyond Christmas with potential for very deep low pressure centres to approach UK around middle of next week. Detail nearer the time.
One other point to raise awareness of, especially as we head into what could prove a rather busy period weatherwise. You’ll be aware from previous briefings that the Met Office are especially keen to obtain as full a picture as possible of weather-related impacts in order to help us evaluate the effectiveness and performance of the National Severe Weather Warnings Service. The Weather Observations Website (WOW) http://wow.metoffice.gov.uk/ already provides a method by which the general public can submit their own weather observations. We have now developed a facility by which weather-related impacts including digital images can also be fed back to us, either via WOW or, perhaps even more conveniently, via the Met Office Mobile site http://www.metoffice.gov.uk/mobile/ . The facility is known as ‘Tell a Forecaster’ and it allows the reporter to assign the impact to one of several categories as well as assigning it one of four levels of severity which are designed to equate approximately to the four impact levels on the warnings risk matrix.
If/when the opportunity arises in the coming days please give it a go. All feedback, +ve and –ve, will be welcome.
That’s all for now,
With kind regards,
Alan Goodman; Met Office Advisor (Civil Contingencies)
