Typically as I was filming a very large bee flew away, but we have wasps in the garden too..in December!
My sister's dog had a nasty swelling on her foot yesterday and wondering if was stung..meds helping..believe bees/wasps more prone to stinging now with food more scarce?

Why such an active jetstream?
Very cold air N America meeting warmer air NW Atlantic fuelling the jetstream
A strong jet can engage with low pressure systems and provide an ideal environment for the lows to deepen, producing more wind/rain

Significant weather pattern developing
Active S displaced E/W aligned jetstream feeding potentially deep low pressure areas into UK 🌬🌧
Jet weak, amplified/or N/S aligned to our E due high pressure blocking Russia- Lows stall & rain builds up

Nearly there ladies and gents
Because of the Earth's axial tilt/ elliptical orbit, the sun will only set earlier by ~3 more mins in the evening before starting to get later again from ~mid month onwards
Despite the shortest day being 21st and latest sunrise occurring early Jan

The N Atlantic tropical storm season has now officially ended for 2025..running 1st June-30 Nov
Been a very interesting season with some metrics running above, others below average overall, masking the finer detail..eg ACE highlighting periods of quiet, then notable activity..
