A weather warning has been issued for parts of Norfolk.
The Met Office has issued a yellow weather warning for the region due to heavy rain.
The warning is in place from 4pm today (September 20) until 3am tomorrow morning (September 21).
It covers most of Norfolk and Suffolk, with the exception of parts of north Norfolk in the areas surrounding Hunstanton, Wells-next-the-Sea and Fakenham.
The Met Office has warned that heavy rain may bring some travel disruption, as well as a small chance of flooding.
It comes after the Met Office said Norfolk will see temperatures lower than 10C overnight in the coming days.
After the heavy rain, tomorrow will be a clearer day with some showers and temperatures remaining in the high teens.
It is high pressure building overnight on Friday and Saturday that will see cooler temperatures overnight across the region, as low as 9C in some areas.
Grahame Madge, a spokesman for the Met Office, said: "It's signalling the transition from summer to autumn.
"Weather patterns over the last few weeks with heat and thunderstorms are much more akin to summer.
"Temperatures are still a bit above average but we're very much into an autumnal feel now."
