The risk is now transfering to scotland and the far north of England. However whatever tropical chararistics the storm had left are nearly gone now, so not expecting anymore significant convective activity, just heavy persistant rain.

The warm moist air is moving into the N sea now, being replaced by cool dry maritime air that will not support thunderstorms.

By midnight the whole of the UK pretty much in the cool dryish air. Ofc there are still likely to be showers as one would expect in a north westerly airstream but they won't be the thunderstorms we have seen earlier today.

Actually looking at this again, NE scotland really does look like its going to get hit badly.

There is still an area of strong but weakening convection that is heading for the NE.

After thunder and lightning either side of 9am in Basingstoke, the squall that came through here after 1pm was noteworthy. Some torrential rain and thunder although in my hometown which is further east it was more explosive with notable TL, hail and biblical rain. Sadly my new garage is completely flooded

If the garage is new, hopefully not too much has been stored at ground level. It's only when rain ingresses that you get an opportunity to work out where you need to install or improve drainage or see where existing flows have become clogged.

The time this sort of event is a real pain is when you store stuff like firewood or electrical equipment on a garage floor and THEN discover the drainage channels which have silted up over the years.

Well, two or three times a decade it does, anyway.

it

My report is pretty much the same as Andy's and not surprising as we live within a few miles as the clouds blow.

Heavy and sustained rainfall all morning and very dark with a few rumbles of distant thunder early afternoon. The sun did come out for a short time, followed by more rain. It's not raining at the moment but there are some dark clouds around and the wind's picked up in the past half hour.

Yes, it was fairly calm until just before that squally storm. It hasn't rained since but the wind has stayed with us and it's feeling rather colder than it's been for a few weeks.

Still pouring down here as the Irish sea rain machine cranks up sending rain inland, if only it was snow and not rain - we would be buried like Jan 2010.

Last night's time lapse as Bertha moves away. Brilliant full moon made the time lapse seem like daytime at times.
