UK Review - September 2010

Heavy rain affected many areas of Northern Ireland and Scotland causing localised flooding.

On the 5th and 6th September, almost 100 mm of rain was recorded at Lough Fea in County Tyrone with 50 to 70 mm of rainfall recorded widely. Surface flooding was reported from a number of locations.

The autumnal weather then spread to much of Scotland on the 7th, when heavy rain and strong winds caused flooding in Dundee and some disruption to ferry and rail services.

The 13th and 14th saw further wet weather across north and west Scotland and north-west England which caused some localised flooding of roads.

Clear skies and a northerly air flow over the weekend of 25th to 26th brought local air frosts to some western and northern areas. The following night was again cold, particularly across Scotland and Northern Ireland.

Some notably low temperatures were recorded, a few places saw their lowest temperatures in September for some 20 to 30 years

The month ended with another spell of wet weather, with over 20 mm of rainfall across central areas of Scotland on 29th and some localised flooding.
