The increasingly hot and humid conditions means that there is a potential for thunderstorms to develop over parts of Cumbria from Thursday evening onwards throughout Friday and into Saturday morning.
The greatest risk of disruption is currently forecast to be on Friday from mid-afternoon through till midnight. A Thunderstorm Warning has been issued by the Met Office for that period. For more details go to:
The areas currently assessed at most risk on Friday are eastern parts of the county and the Pennines, though there is still a fair bit of doubt as to exactly where and when any storms may strike. Areas outside that may not be completely immune.
Such storms can cause torrential localised downpours causing impacts such as the overwhelming of drainage systems, which could result in surface water flooding and cause disruption to road/rail/pedestrian travel. Properties may also be at risk with rapid run-off possible from the exceptionally dry ground and potentially localised flooding from smaller rapidly responding upland and urban watercourses.
We are monitoring the situation closely and Operations Teams are ensuring our assets such as debris screens and grids on watercourses are clear.
Any risk of further thunderstorms should reduce by Saturday afternoon. Sunday will then see rain spreading across the county from the west during the morning potentially lingering for much of the day. The rainfall may be heavy and persistent at times over the fells and high ground but is unlikely to be disruptive. Next week the dry spell looks set to resume.
If further details become available this message will be updated.
