Surprisingly, despite all
the rain we had no named

atmospheric pressure rose
to 1034 hPa on the 1st but

mainly from the southwest with a maximum gust of 27 mph on the
26th.
There were seven days
with no sunshine at all,
with a total for the month
of 53 hours, which is

February average. Note

taken for the excess water to drain into the rivers. Whilst the
immediate rainfall into the river has some effect on the water
level, it’s the rainfall over the countryside, which drains into
gullies, brooks and streams, and eventually into the rivers that
causes the rivers to flood. After all, the surface area of the
river is small compared to that of the surrounding
