Despite the UK enjoying forecasts of soaring temperatures and sunny weather, the Environment Agency has issued numerous flood warnings and alerts throughout the country. As of 1.30pm on Monday, 31 March, there are 31 flood alerts and 4 flood warnings in place across England, impacting thousands of residents.

The distinct lack of precipitation has not coincided with the warning statuses, as only a day prior, on Sunday, more than 80 flood alerts and warnings were issued across various regions including South West England, North West England, North East England, and South East England. However, following changes in conditions, 61 of these warnings were subsequently removed. The remaining warnings apply to specific areas, including the Mersey Estuary in Warrington, Cheshire, Hornsea in Yorkshire, Brockweir in Gloucestershire, and the Alkborough Flats in Lincolnshire. Residents in these locations have been urged to avoid beaches, promenades, and coastal footpaths, in order to stay safe from “dangerous large waves and sea spray.”

This unusual situation, where flood risks persist despite predominantly dry weather, can be attributed to tidal forces exacerbated by spring tides and strong winds. As explained by the Met Office, spring tides are not related to the season, but occur during the full Moon and new Moon phases when the Sun, Moon, and Earth align. The recent partial solar eclipse on 29 March coincided with this lunar alignment, resulting in stronger gravitational forces that have resulted in higher than normal tides.

Compounding the situation, tidal surges can lead to abnormal rises in sea level, driven by strong winds that push seawater towards the coast. Even amidst dry weather, these surges can result from atmospheric pressure changes that draw water shoreward. When such tidal surges occur synchronously with spring tides, the resultant higher sea levels present greater flooding risks for coastal areas.

In addition to flooding caused by tidal actions, the Environment Agency has warned of continuing “stormy conditions” at sea and noted the lingering effects of winter rainfall which have left certain areas waterlogged. Consequently, individuals residing in regions under flood alerts have been advised to refrain from using low-lying footpaths or bridges near watercourses, and to avoid attempting to walk or drive through floodwaters.

The alerts and warnings reflect the ongoing complexities of weather patterns and their interactions, particularly in a time of year when spring weather is typically anticipated.
