Tollcross pool closed and roads flooded as rain sweeps Scotland Flood alerts are in place across Scotland as thundery showers sweep the country. Rainfall estimates suggest that around 20mm fell on Thursday in the Glasgow and Ayrshire areas as well as southern parts of Argyll and Bute. The Scottish Environment Protection Agency (Sepa) has "be prepared" flood notices in place across much of the country. Forecaster Billy Payne, from Meteogroup, the weather division of the Press Association, said: "The rain band is moving north and breaking up with heavy thundery showers across southern and central Scotland. There have been a few lightning strikes in the Glasgow area and it's possible that 20mm of rain has fallen locally since daylight began. The Scottish Fire and Rescue Service said they had received several calls to report flooding in the Strathclyde area since 5pm. Road maintenance firm BEAR Scotland has postponed resurfacing works on the southbound M9 due to take place at the weekend because of the wet forecast. The work on the stretch between junction 9 (Bannockburn) and junction 8 (Hill of Kinnaird) will be carried out at a later date. MeteoGroup said 18mm of rain was recorded in Drumnadrochit in the Highlands between 7am and 7pm today. Islay received 16mm and 14mm fell on Prestwick in Ayrshire. Roads in Greenock were also flooded, and a large fire in a block of flats is suspected of having been caused by lightning. In Glasgow, the newly-refurbished Tollcross International Swimming Centre was forced shut because of problems with the building's rainwater system. The centre will host swimming events during next summer's Commonwealth Games. A spokesman for operators Glasgow Life said: "Tollcross International Swimming Centre has been forced to close as a result of today's adverse weather conditions and an issue with the building's rainwater system. Glasgow Life is working with architects and contractors to rectify this and the facility will reopen as soon as possible. We apologise for any disruption to customers.
