UPDATED: People in Hull and East Riding are being urged to take heed of weather warnings as ex-Hurricane Bertha makes its way across the Atlantic.
The Met Office have warned the next 24 hours are "critical" as they try to predict where the tropical storm, which has been battering the Caribbean, will head next.
There is a 60 per cent chance it will hit the south of England on Sunday, and a risk it will then head north, bringing with it heavy rain and coastal flooding.
A Met Office spokesman said of Hull: "The next 24 hours are critical. Hull should escape the worst of it but that is still very uncertain.
"There could still be very heavy rainfall and the second highest spring tide, so there is the potential, if Hurricane Bertha changes direction, it could cause issues for coastal flooding with very large waves.
"People need to be really aware and keep up to date with the warnings.
"The best-case scenario is it misses the UK completely and goes to the north of France and if that is the case, it could actually be a good day weather-wise.
"It is all about seeing what happens in the next 24 hours."
The Met Office has a yellow weather warning in place for Sunday in anticipation of heavy rainfall and the Environment Agency says there is a low risk of flooding. However, following showers this afternoon and evening (Friday), Saturday is shaping up to be a "relatively nice day" with sunshine and temperatures as high as 21C.
Monday will bring sunshine in the morning and showers in the afternoon, with wind gusts reaching 35mph, and more heavy showers are expected on Tuesday.
Hull forecaster Lewis Dobson, of UK Weather Forecast, said his models showed Bertha hitting Britain in the south-west before heading in a north-easterly direction, with Hull escaping the worst of the rain.
He said: "For Hull and the East Riding, there will be a spell of wet weather during Sunday morning, although the heaviest rain will be across Northern Ireland, north-west England and north-west Scotland.
"The main feature for our region will be strengthening winds on the southern flank of the low; isobars will tighten which will lead to gusts of 40-50mph for a time, possibly 60mph for coastal areas as Bertha moves into the North Sea.
"With an occluded front wrapped around the centre of the low, further showers or longer spells of rain are possible later in the day."
