On February 23rd it was Storm Doris that had the largest impact across our region. There was a gust of 81 mph recorded at Weybourne on the Norfolk coast, gusts of 65-70 mph were reported quite widely inland across the region. This caused some disruption to transport with power outages and numerous fallen trees (as shown above).

January was the only colder than average month of winter and 2016/2017 saw remarkably few days with lying snow in our region. There were only seven days on which falling snow was reported and no ice days recorded at the six stations used in this report.
