A YELLOW warning for rain will be in place from tomorrow in parts of Devon as “heavy showers, perhaps thundery, are possible”.

The weather warning will be in place from Wednesday night (September 4, 9pm) into Thursday night (September 5, 11.45pm), the Met Office said.

The latest forecast said: “Whilst there is some uncertainty, and not all areas will be affected, scattered heavy showers on Wednesday evening may merge into longer spells of heavy, showery rain in places through Wednesday night into Thursday morning.

“Where heavy downpours occur, perhaps thundery in places, accumulations of 20-40 mm are possible in an hour or two, with the small chance of isolated accumulations over 50 mm, potentially impacting the Thursday morning commute in some areas.”
