Windy last night, with gusts widely to 40mph in the far SW. Also mild,
with a minimum of11.8C.

14.2mm of rain overnight, but it cleared eastwards around 08:00 with
the cloud already starting to break. The overnight force 5-6 SE has
now become a Force 2-3 S just behind the front.

I see there's a heavy rain weather warning for Cornwall & the Isles of
Scilly from 10:00-15:00. It's been & gone here, and will have cleared
most of Cornwall by 10:00. *Heavy rain here was 04:00-07:00.

The warning was issued at 08:00 - shouldn't it be issue before rather
than after the event?

Yes I know, the thing is the warning is fine for Devon, but for
Cornwall was affected from the early hours until 07:00 in the far west
to 10:30 (in the far east). So giving a warning from 10:00 was
incorrect. I've just returned from Mousehole, in sunshine. to speak to
my visitors who had just changed their plans for a walk, due to the
forecast. They've now set off in sunshine.

As MCC says, there was flooding in west Cornwall - well before the
period covered by the warning. In Penzance, along the prom due to the
sea overtopping (spring tide, low pressure, rough sea). I didn't see
any warning for coastal flooding.

It does seem very silly being as the warning was issued at 0800.
I never understand why they don't look at the radar rainfall to give a
better indication of timing for frontal rain.
We are after all talking about nowcasting in such circumstances.
Only rained for about an hour and a half here in Wembury SW Devon.
No sun yet though.
