The current yellow warning from the Met Office ran out at 2355 BST. Todays warning for much further north didn’t start till 0005 BST, so technically there was no warning out for around midnight.
I would have thought that the Chief forecaster would have extended the one for Wednesday to cover the south coast, especially with SFERICS and heavy rain all along the south coast.
There is obviously some rule that gets him out of doing this, but in the light of what happened at Coverack, you would have thought it sensible for him to do this, because the intensities in the weather radar are very similar to yesterday afternoon. What happened at Coverack could happen again anywhere along the south coast during the night.
So here in mid Devon at 0010 BST, and close to Exeter, we have a thunderstorm and heavy rain, but are outwith the warnings area for today which starts around the M4.
