June 2007 was a record breaking month for the Sheffield and South Yorkshire Region it will be remembered for the wettest month on record locally and yet despite all the rain it was a warm month. In keeping with the last month we have entered July with the Atlantic Systems lying further South across the country than what they usually do. The month was dominated by winds from a Northerly quadrant a total of 12 days with a further 5 days with an Easterly flow. The highest wind was recorded on the 25th with a gust of 30 mph and all day speeds of 15 mph plus was recorded. Despite the winds from the cold quadrants. The period 8th to the 13th saw maximum temperatures of 20c+ with a maximum of 25.3c on the 11th. Overall the temperatures were above the normal and this despite the short supply of sunshine as on 91.29 hours were recorded during the month. The lowest night temperature was during the night of the 2nd when the ground temperature fell to 3c. During the month we had 4 storms, the first was singled the start of the major rain fall I heard a single clap of thunder at 15.30 hours on the 13th then the rain commenced over the 13th to 17th I recorded 122mm of rain this was the catalyst for the major flooding during this period we had a further storm on the 15th from 19.00 hours to 21.00 hours with quite vivid lightening. This was the first major flooding as our area borne the brunt of the rain 88mm was recorded. On the morning of the 15th we woke up in Chapeltown to torrents of water and the centre of the village was cut of with floods up to 5 feet deep. The two local roads across the road by my home were closed as water poured out of the woods at Grenoside. This torrential rain flooded the ground and major run off occurred as the ground could not absorb any further water. The evening of the 19th saw a further heavy storm from 21.30 hours to 22.30 hours and it was a light storm. The heaviness on the atmosphere could be felt and during the night i.e. the early hours of the 20th we had a strong heavy storm which started with a cloud to ground discharge then there was a spectacular display of cloud to ground lightening. These two storms gave a total of 24mm of rain added to the 14mm which was recorded on the 17th. To this saturated ground on the 0n the 24th and 25th most of the rain commencing after midnight of the 24th a total 107mm was recorded on the Monday and Tuesday we had a repeat of the previous road closures but this time part of the major A61 trunk road from Sheffield to Barnsley was washed away resulting in its closure. I am thankful we live on the higher ground as parts of Hillsborough, Central Sheffield and the Don Valley were like a war zone on the Tuesday Morning. The events are well chronicled from various sources with many stunning photos and BBC Look North and Yorkshire Television reported the events. I even had emails from friends in Kenya asking if my wife and I were safe and well as it was on National Television there as well. The total rainfall for the month was 318mm and it was indeed a record breaker. Media Brief Week Commencing Monday 25th June 2007 This week will always be in the memory of the people of Sheffield and Rotherham. Sadly a few deaths occurred but so many people had to walk miles home in torrential rain with transport halted by flooding and road closures. The RAF helicopter crews were scrambled to the Don Valley to winch people from the roofs of industrial premises as the River Don burst its banks in The Lower Don Valley reclaiming its natural flood plain. The huge Shopping Complex at Meadowhall was flooded and was closed for a full we even now at the beginning of July only the upper floors are open as stock on the lower floors s damaged. In Brightside a rescue boat negotiated cars that were hurting along in the flood like missiles to rescue trapped people. In the Hillsborough and Neepsend areas the river also burst its banks taking out a sub-station cutting off power to many homes in the process. Emergency accommodation was set up in various places. The pitch at Sheffield Wednesday Football Ground was flooded. Apartments near the town centre in Neepsend, Corporation Street and Nursery Street were flood on the ground floors. Parts of Heeley Bridge were flooded as the drains could not cope with the volume of water. Overnight it was observed that the reservoir at Ulley was beginning to leak and the local villages in its path were evacuated. The M1 motorway was closed and just the other side of the motorway concern was expressed that if the wall burst a major power distribution site would be flooded and thousands of homes would loose power. A major emergency swung into action as many pumps were used to lower the level of the water behind the wall so that emergency work could take place. The emergency moved downstream to Doncaster and I am sure other observers will file dramatic reports as areas in that town are still under water on the 3rd July. Rotherham Railway station is also still flooded and trains are not using it. On Wednesday 27th in an approaching shower I observed a Funnel Cloud over The Woodhead Pass Area. How did this event occur? Thunderstorms and rain associated with the low pressure that tracked North East across the country 1000 – 1007 mbs saturated the ground and produced the conditions for further major flooding this total of 132 mm of rain over the 3 days was high causing flooding. The 14mm on the 17th together with the 24mm on the 19th, the 9mm on the 21st and finally the 6mm on the 22nd kept the ground wet with water continually running off. All that was now needed were the right metrological conditions so far in this disappointing summer the Low Pressure Systems across the country have settled 300 miles South of their usual track to the North of Scotland. The low 999mb Monday 25th and its strong winds maximum gust 30 mph were the cause. The original low moved North East and a further low pressure area formed off Cornwall and Devon. This combined with the warm air moving up from France and the colder drier air moving down from the North gave the right conditions for a slow moving band of heavy rainfall. This band sat over Northern England with its Southern Edge directly over Sheffield. The rainfall started as I was finishing work at midnight on Sunday and continued until late Monday evening. The heaviest bursts were from 16.00 hours to 17.00 hours when rain was running down the roads like rivers and it was a nightmare journey home from work for those who made it home. Finally the rain moved away South Easterly. Rain falling in such volumes on saturated ground just run off the 107mm that fell caused the flooding as it was in a period of 22 hours. |

It notable feature this month was the lack of rain.
