Storm Babet

Storm Babet hit NE Scotland on 2023-10-19 and last 48-56 hours. With very strong easterly winds and heavy rain.
There were serious floods in Brechin area (Angus) as a resut. Storm damage and local flooding occured over a wider area.

Graphs showing the extent of the rain and wind at the Clair Observatory due to Storm Babet are shown below.

Rain:
Image

Observatory was checked on 2023-10-21 in late afternoon after rain had eased off. There was some water entry in the vicinity of the observatory door, which faced east and was thus prone to the driving rain leaking round the margins of the door.  The door mat was found to be soaked through,  and water had gathered below the rubber floor mats.  Checking further showed there had been some water entry from under the observatory walls but it was relatively minor.  The door mat and 50% of the floor tiles were taken up and dried.  These were placed back in their positions the following afternoon (2023-10-22).

Wind:

(Note : actual wind speeds were higher than recorded by the wind speed sensor, which was situated on the lee side of the house.)
