Heavy rain and gusty winds threaten to dampen spirits at Lewes Bonfire this weekend.

A yellow weather warning is in place for rain across southern parts of Sussex from 3pm on Saturday until the end of the day.

Flooding of some homes and businesses is possible, with the Met Office warning of dangerous conditions at the coast.

It comes as the bonfire celebrations in Lewes are due to take place, with hundreds of people expected to line the streets of the town for its annual procession.

Cliffe Bonfire Society has already announced that its firesite for the event will be closed to the public due to the weather conditions.

A spokesman for the Met Office said: “A spell of heavy rain followed by frequent heavy and blustery showers are expected to affect southern coastal counties during Saturday.

“Around 20-30mm of rain could accumulate in some places with perhaps as much as 40mm by the end of the day.

“Accompanied by strong winds along the coast, these showers are likely to cause flooding of a few roads, leading to travel disruption and possibly the flooding of a few homes and businesses.

“In addition, dangerous coastal conditions with large waves and spray are likely.”

Heavy rain also struck last year's Lewes Bonfire event, but that did not deter hundreds of people from flocking the town to enjoy the festivities.

It comes as Storm Ciaran batters the Sussex coast with gusts of more than 60mph, causing roads to be blocked by fallen trees, disruption to rail services and flight cancellations.
