Britain is facing a prolonged period of wet weather, with forecasts predicting up to 10 days of rain. Multiple cities across the UK will experience daily downpours, including Bristol, Sheffield, Liverpool, Belfast, and Manchester. The Met Office predicts an unsettled period with a frontal system dominating southern areas, leading to strong winds and cooler temperatures along eastern coasts. Despite hopes for a warm end to April, the next few days are expected to bring cold and wet conditions. The long-range forecast indicates a possible north-south split, with drier conditions expected in the north and a higher chance of rain in the south. Meanwhile, hay fever sufferers are advised to prepare for an early onset of symptoms, with pollen counts expected to peak around this time of year.
