Yellow weather warnings for heavy rain have been issued for parts of Merseyside on Tuesday and Wednesday, as the storm that has brought record snowfall to the U.S will hit the UK.

By the time the low pressure system arrives it will be much weaker storm and most of the snow will have turned to rain due to our milder temperatures.

However, as the low crosses the Atlantic it will pick up tropical moisture, resulting in very heavy rain for parts of the U.K.

The Met Office have issued severe warnings for heavy rain as flooding is possible in parts of the warning areas, up to 100mm of rainfall could be expected in places across the north west.

Helen Roberts, a meteorologist at the Met Office said: “The same low pressure weather system will affect weather in the UK and remnants of that storm will travel across the Atlantic, although it will be extremely modified.

“The weather is expected to be pretty mild, although heavy rain is expected over a two-day period next week, which may also bring some sleet and snow in higher areas.”

 

A chief forecaster at the Met Office also commented: “Warm air of tropical origins is expected to be entrained into the system, leading to abundant moisture and heavy rain.

“Many parts of the warning area could see 50-100mm of rain, whilst the most exposed upland parts of North Wales, north-west England and south-west Scotland could see 150-200mm.

“As such, there is the potential for river flooding, and also standing water on roads. Strong and gusty south-west winds will also develop.”

Storm Jonas has brought record amounts of snowfall to the east of the US and all non-essential travel has been banned in New York, transport suspended and bridges shut as the city is hit by one of its worst snowstorms.

Parts of the eastern United States have received 40in (102cm) of snowfall during the storm.
