Surprisingly, despite all
         the rain we had no named
         storms! The sea-level
         atmospheric pressure rose
         to 1034 hPa on the 1st but
         fell to 976 hPa by the 9th.
         The average pressure was
         1010 hPa. Winds were
         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
                                                  seven percent below the
                                                  February average. Note
                                                  how the UV Index
                                                  readings (in red on the
         chart) are rising as the month progresses. This is due to the sun
         gradually rising higher in the sky.

         Why doesn’t the bridge at Offchurch and other places flood
         while it’s raining?

         “It poured with rain all day and yet the bridge was clear of
         water in the evening. It was dry overnight and yet the next
         morning the bridge was flooded and remained so most of the
         day even though there was no more rain.” This delay
         experienced in Offchurch and other places where roads are
         prone to flooding after prolonged heavy rain is due to the time
         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
