According to the Met Office, the central pressure within Storm Callum dropped from 986 to 938mb within 24 hours. That astonishing 48mb drop 24 hours made Callum an ‘atomic bomb’ cyclone, doubling the 24mb within 24 hours drop to constitute a ‘weather bomb’. It also broke the 1979 record of 939mb for early October

UK IMPACTS
Thankfully the core of strongest winds remained out over the Atlantic but gusts of 75 to 86 mph were still felt in exposed parts of Ireland and Wales.

Rainfall was the biggest impacts as a trialing front extended from Callum, down over the UK and hooked up with Hurricane Leslie near the Azores. Slow movement of this boundary and injection of tropical energy led to heavy and persistent rainfall widely.
Like we saw with the start of the week ‘atmospheric river’ in NW Scotland, as much as 9 inches of rain has fallen in Libanus, Powys since the beginning of yesterday.

This afternoon under sunny skies, it soared to between 23-26C widely. It was the warmest mid October day since 2001 but warmest for so late in the year on record.

The previous record for latest 26.0°c temp value in the calender year was October 9th – way back in 1921 when the temperature actually leaped straight past 26°c and peaked at 27.8°c. Prior to today, no day in the calender year after October 9th had recorded 26.0°c#HOTober ?️??️ pic.twitter.com/VJfEbC7r4L
