The Met Office has issued a yellow alert for St Albans, with heavy rainfall, thunderstorms, and possibly hail forecast for tomorrow afternoon.
The rain is expected between 1pm and 11pm on Friday, June 2, most likely at 2pm, when there is a 40 per cent chance of rain.
The Met Office has said very warm, humid air coming up from France is creating the threat of thunderstorms, which could produce between 25 and 30mm of rain in an hour.
This particular yellow alert means the rain would be highly impactful, but is not considered very likely.
The alert covers most of Hertfordshire, including Stevenage, Welwyn Hatfield, and Hemel Hempstead, as well as Essex and East Anglia.
There is the risk the rainfall could create some surface water on the roads, which won’t be helped by frequent lightning and possible hail.
