The amber weather warning is in force in parts of Hertfordshire and Essex from 3pm until 11pm on Thursday 23 June 2016.

The yellow weather warning is valid until 2am on Friday 24 June 2016 and covers the entire Anglia region.

The Met Office is warning of possible disruption to travel and localised flooding as well as frequent lightning.

The Met Office says there is a risk of thunderstorms affecting the London area this afternoon and evening.

Although some areas will miss them, potentially intense thundery downpours are likely elsewhere in the Anglia region this afternoon and evening before they clear later this evening or during the early hours of Friday.

"Another wave of thunderstorms breaking out across southeastern UK this afternoon and evening is likely to bring some thunderstorms into the London area.

"Whether these storms are as severe as those of last night is, at this stage, uncertain, but in view of storms being expected during the afternoon and evening impacts may be as widespread as those of last night and first thing this morning.

"Warm and humid air has spread into roughly the southeastern quarter of the UK, bringing with it a risk of thunderstorms this afternoon and evening. Where thunderstorms occur torrential rain and frequent lightning are expected.

"30 mm or more of rain could fall in an hour and locally in excess of 50 mm is possible in two or three hours."

The Met Office warning is in force from 6pm on Wednesday 22 June until 6am on Friday 24 June 2016

The Met Office says although some areas will miss them, potentially intense thundery downpours seem likely to affect parts of the warning area from Wednesday late afternoon or early evening onwards into the early hours of Thursday or Thursday morning.

Further scattered thunderstorms are then likely to break out from Thursday afternoon onwards into Thursday night.

The Met Office is warning people to be aware of possible disruption to travel and localised flooding as well as frequent lightning.

"Increasingly warm and humid air arriving from France later on Wednesday brings with it a risk of thunderstorms.

"These thunderstorms are likely to occur in a couple of main waves, from Wednesday late afternoon or early evening into early Thursday and a second wave breaking out later on Thursday.

"Where thunderstorms occur torrential rain and frequent lightning are expected, as well as a chance of some hail. 30 mm or more of rain could fall in an hour and locally in excess of 50 mm is possible in two or three hours.

The Met Office says that the northwestward extent of these thunderstorms remains a little uncertain and parts of southeastern England are considered most likely to be affected.

With this in mind an amber warning has been issued for this area from Wednesday evening through until early Thursday.

The yellow weather warning is in force from 10am until 10pm on Friday 17 June 2016

The Met Office says heavy showers are expected to redevelop on Friday, organising into slow-moving bands in places, and leading to some torrential downpours.

The forecaster added: "As on preceding days some locations will miss these downpours, but please be aware of possible localised flooding and disruption to travel where they do occur. Lightning could be an additional hazard."

"In addition to the residual, heavy showers overnight, the daily rise in temperature will once again trigger slow-moving heavy showers and thunderstorms.

"However, unlike preceding days the area affected is expected to recede southwards and eastwards through the day.

"Once again, 15-25 mm, and very locally in excess of 30 mm could fall within an hour, bringing the risk of flooding, especially if they occur across urban areas."
