More information is emerging of the amount of rain which fell in the Stonehaven area on the day of the accident, which surprisingly Network Rail and the Met Office have been strangely quiet about.

 

One report from CNN states:

 

Inverbervie station, the closest reporting weather station averages 57.6mm in August. They have recorded 55mm in 24 hours, so almost exactly a month’s worth of rainfall in 24 hours, with the bulk of it coming between 3 a.m. and 8 a.m. local time this morning.

This tallies closely to the data from a private weather station in Stonehaven, which recorded 56mm during the period, most of which fell between 6am and 8 am.

As I reported at the time, daily rainfalls of that amount are not unusual in the area:

Whether  previous episodes have taken place over such a short space of time is difficult to know, because hourly data is often not available for those.

 

The daily record of 83.9mm at Dyce, Aberdeen was set in July 1970, but was the result of long downpours, rather than thunderstorms. The Met Office monthly report tells us that it was an extreme month in many ways:

Interestingly though, July 1971 did experience extremely high rainfall totals, associated with thunderstorms up and down the country, including 72mm at Callendar, Perthshire, which is not far from Stonehaven:

When we look UK wide record rainfalls of course, Stonehaven’s downpour pales into insignificance:
