Hi everyone, have decided to start up a separate topic to look more closely at expected rainfall accumulations in the days ahead. It's a concern that more new floods are possible if not likely through this weekend and into next week, this coming from several large scale weather systems and possible Atlantic storms hitting the UK and ROI over the next 7 days at least, it's likely that some breaks in the rain will occur at times though.
I'm not going to hide the fact that severe floods in new areas are possibly on the way I say possibly even if I think likely, which I do.
Below I've put on a rain alert map created from precipitation data models of which the one's I have access, please use my map as a general guide of where the heaviest rain could be accumulated over the next 48hrs or so, please do allow for some small adjustments do not take the map as 100 percent set in stone, usually the expected accumulations of rainfall may be more or less in any one area and exact locations can change, I might not be able to update map.
(Map can be shared where you like)
Map expires MON 0300hrs - January 4
W = on the map this means that I am watching for upgrades of 30mm or more.
Light yellow + W =30mm - rainfall may get accumulated up to 30mm but may upgrade to 40mm for a level 1 so is under a watch zone.
Yellow = 40mm - 50mm accm rain
Orange = 50mm - 80mm accm rain
Red = 80mm - 100mm accm rain
Dark red = 100+ accm rain.
Many areas seeing rain this heavy at times some very heavy and prolonged, expect 10mm-25mm generally.
Some of the largest rainfalls likely to occur over higher ground.
For the winds associated with these weather systems/storms likely gale or severe gale at times please see other threads and warnings.
Please post anything related to rainfall forecasting, model ppn data, alerts and warnings, your own rain maps and forecasts.

This weekend is looking quite wet in places with some flooding possible with large rainfall totals possible in 12-24hrs. Also the wind may play a part with gales possible and given the time of year with trees in full leaf accompanied with a lot of rain may cause branches or trees to fall causing disruption.
The Met Office have an early warning out for the rain:
Still uncertainty regarding where the heaviest rain will be and how deep the low will also be but its worth keeping up to date with.

Here is a selection of wild weather photos that I have collected from the web.
The thread gallery here contains almost 70 incredible photos.
Apart from an amazing gallery of photos the question is are these severe weather events around the world becoming more extreme, not only this but are they becoming more frequent?
