As Britain counts the cost of extreme weather, the forecast is there's more to come After two weeks of gales and mass flooding over the Christmas and New Year period, between 10mm and 15mm of rain, and up to 30mm on higher ground, is expected to hit southern England before moving north-eastwards. Heavy rain is also expected in parts of Northern Island and Scotland. Heavy rain yesterday afternoon and into the early evening across many areas of the UK caused the Met Office to issue severe ice warnings for North Wales, Scotland, north-west England and down into parts of the Midlands overnight. The Environment Agency (EA) had more than 90 flood warnings in place yesterday evening, signalling that immediate action should be taken, plus more than 250 less severe flood alerts. Soldiers in Kent were yesterday joining efforts to protect homes with sandbags. Last night, Environment Secretary Owen Paterson insisted that flood defences had so far "worked well" but that the "worst" of the bad weather was not yet over. Jonathan Day, flood risk manager at the EA, said "The risk of flooding to the coast will continue over the next few days, especially on the south and west coast and along the Severn estuary. In addition, wet conditions have left the ground saturated in many areas, increasing the risk of river and surface-water flooding. He added: "We would urge people to be prepared by checking their flood risk, [and] signing up to free flood warnings." Coastal flooding occurred overnight on Friday, with people waking up to scenes of devastation on sea fronts around the country. Harry Martin, 18, was still missing yesterday, having last been seen approaching a Devon coastal path on Thursday. It is believed the teenager had been going to take weather-related photos near his home in Membland, Newton Ferrers. More than 100 people joined search and rescue teams yesterday to look for him. The lure of spectacular waves still proved too much for some yesterday, despite repeated requests from government agencies, police and ministers to stay away from coastal areas. A man had to be rescued by lifeboat after he photographed waves from a harbour jetty in Aberystwyth on the west coast of Wales. Another man was pulled from the sea at Newquay in Cornwall by police officers early yesterday morning. A 27-year-old man from Surrey was found on Porthleven Sands beach in Cornwall after he was swept out to sea on New Year's Eve, and a woman died after being pulled from the sea in Croyde Bay, north Devon. The holiday resort town of Aberystwyth was particularly hard hit by Friday's flooding, with images coming out yesterday morning of the sea-front having been damaged by tidal surges. Aberystwyth University deferred the start of its exam period for a week. Around 90 properties are believed to have been flooded since Friday, bringing the total to around 220. There were also more than a dozen flood warnings in Scotland. The EA said parts of the north-east coast, including Whitby and South Shields, could also be flooded overnight, while parts of the south coast, including Portsmouth and Newhaven, might have more coastal flooding today and tomorrow. Rivers in Dorset, Hampshire and Wiltshire could also rise. The EA said the coastal surge in recent days had tested over 3,000km of flood defences in England, but that more than 205,000 properties have been protected. Flooding from the deluges during the Christmas break is still affecting rail travel in certain regions including areas of Wales, Gloucester, Southampton and Carlisle. Although many services are expected to be back to normal by today, there are long-term closures on the Isle of Wight. Prime Minister David Cameron praised the "great work" of the emergency services and the EA in tweets yesterday. Mr Paterson, however, remains under pressure over job losses in roles connected to floods work at the agency. He has insisted that "frontline services" would be protected, but the EA chief executive, Paul Leinster, has admitted roles in flood-risk management are likely to be among 1,500 job losses. The losses come after more funding was pumped into flooding and coastal risk management over the past year and into the next two, after the Government cut funding when it come into power in 2010. An EA spokeswoman said: "We are currently consulting on new structures for the organisation. It is forecast that the 11,250 staff members will remain until the end of March and it is expected that numbers will be cut to 9,700 by October. Anne McIntosh, the chair of the Commons Environment, Food and Rural Affairs Select Committee, told Sky News: "To be honest with you, I don't think this is the time to look at an agency that is working flat out, as to how it will spend its future resources."
