North Sea coastal towns, such as Withernsea and Bridlington, also face tidal risks.Norfolk Broads & the East Coast - low-lying marshes between Norwich and Great Yarmouth regularly flood during high tides and river surges.Oxfordshire - across the Upper Thames catchment and into the Cotswolds.Mersey Estuary - high tides and storm surges push up the estuary from the Irish SeaLondon - the map also shows many high risk spots in Central and West London, although these are largely protected by the Thames Flood Barrier.‌Storms and more extreme weather on the way this yearHayley Fowler, professor of climate change impacts at Newcastle University, warned that though El Nino was a natural phenomenon that occurred every two to seven years, it is set to unfold in a "climate already loaded towards extreme heat", caused by burning of fossil fuels.She said this year Britain could witness weather events similar to Storm Desmond, which hit in late 2015 during the last strong El Nino. Three people died amid widespread flooding, and the storm caused an estimated £870 million in damage nationally.Article continues belowProf Bill McGuire, professor emeritus of geophysical hazards, University College London, said the Met Office and other in-depth forecasts "suggest that the world is in for one hell of a ride" in the months ahead."The astonishing and unprecedented amount of heat building across the eastern Pacific Ocean is all but certain to make this the most powerful El Nino in living memory - possibly even the biggest in several centuries" he said.Households have meanwhile been warned that El Nino could hike the price of everything from food to electrical gadgets as its impacts are felt at home and abroad, following on from a summer of record-breaking hot weather.Choose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌WeatherEl NinoFloods
