UK heatwave: Hour-by-hour forecast as amber weather warning hits Sussex

The beginning of next week will herald scorching temperatures in Sussex.

Temperatures are forecast to soar in Sussex over the next few days and the Met Office has issued an amber weather warning for the region.

According to the Met Office’s weather warnings guide, an amber warning means there is an increased likelihood of impacts from severe weather, which could potentially disrupt your plans.

This means there is the possibility of travel delays, road and rail closures, power cuts and the potential risk to life and property.

A red extreme heat warning has been issued by the Met Office for parts of England on Monday (July 18) and Tuesday (July 19).

Temperatures could hit 40°C, meaning a danger to life is likely, with the risk of illness not limited to vulnerable people.

Extreme weather warnings are in place for the whole of England and Wales from Monday at 12am to Tuesday at 11.59pm.

According to the latest forecast, the extreme weather in Sussex should begin on Monday, although today (Sunday, July 17) is forecast to see highs of 29°C.

A Met Office spokesperson said: “Exceptional, perhaps record-breaking, temperatures are likely on Monday, then again on Tuesday.

"Nights are also likely to be exceptionally warm for the UK, especially in urban areas.

"This is likely to lead to widespread impacts on people and infrastructure. Temperatures are expected to drop away from Wednesday onwards.”

Here is an hour by hour forecast for Monday and Tuesday:
