"This exceptional month was dominated by winds from a southerly
quarter almost throughout.

With pressure now high over eastern Europe a mainly southerly type
persisted until the 18th, although a vigorous frontal trough moved
very slowly eastwards across the UK between the 11th and 13th,
followed by a sharp but short-lived rise in pressure.

Torrential rain in many western districts led to serious but short-
lived flooding, notably in Wales and Cumbria.

A trough advanced across the country from the southwest on the 19th,
introducing a cyclonic spell which lasted until the 25th. Rain fell
frequently and often heavily, and hail and thunder occurred in many
places.

Some 68mm of rain reportedly fell at Ottery St Mary (Devon) on the
19th. It became somewhat colder for a few days in Scotland with some
hill snow.

Further flooding was reported on the 24th, notably in Northern Ireland
[and Wales] between the 23rd and 25th."

[A massive Atlantic hurricane ( Wilma-05) ran from15th to 25th
October.. I'm not sure when it became a category 5 but it changed the
power of the spell from a mere wet and warm one to one with thunder
in. That's a knock back of 4 hours in the phase.]

"A broad SSW-ly flow brought tropical air from unusually low latitudes
during the last seven days of the month. The weather was warm but
largely cloudy with rain at times, heavy in the north and west, but
the 27th was notably sunny. The 31st was wet in the Southeast and East
Anglia."

[Two major tropical cyclones were running at the month's end:
27th to31st October.. Cyclone category 3. BETA-05. Atlantic and 29th
October to 2nd November.. Cyclone category 2. KAI-TAK-05. NW Pacific.

If the knock back is 4 hours for a Cat 5 and a Cat 1 is nearly zero,
then the knock back on these was 2 hours for the first and 1 hour for
the second at their respective heights.]
