The Met Office has advised the County Council that we may be getting severe weather later today and perhaps tomorrow. With the obvious pleas not to shoot the messenger, here is what they have to say:
The probability of Cambridgeshire being within the area of concern, or outside it, is very marginal BUT there is the potential for heavy thundery showers during this afternoon and evening, possibly persisting overnight into Saturday.
Showers may be slow moving across the County resulting in surface water flooding, giving some high totals in places . Potential rainfall scenarios are:
Best Estimate Scenario:
10mm in 1hr (locally);
20mm in 2hrs (isolated);
30mm in 3hrs (isolated).
Reasonable Worst Case Scenario:
20mm in 1hr (locally);
30mm in 1hr (isolated);
50mm in 2hrs (very isolated);
50mm in 3hrs (isolated).
The issue with ‘slow moving’ showers is that it is very difficult to state where exactly and when exactly the rainfall will, if at all, fall within the County. But if it does fall within an isolated area of the County we could experience that in August 2014 where a number of major roads a were closed and properties flooded.
The risk from rivers remains very low and there is no anticipation of the issuing of widespread Flood Alerts and/or Flood Warnings for river flooding.Leave a comment
