Radar and Lightning Maps

Rainfall Radar

The link below shows animated rainfall radar images at 5-minute intervals of West Mersea and the rest of Essex over the past 90 minutes.

Different colours indicate how heavy precipitation is that is falling to the ground. For example, areas of yellow and orange show heavy rainfall (or snowfall in winter). Thunderstorms are often indicated by red or pink colours.

Lightning Maps

The link below enables weather observers to track thunderstorms in and around southeast England and the near Continent.

The lightning data is shown on a map in real-time, but depending on server load (especially during severe weather outbreaks), there may be a delay between 3 and 10 seconds before each new strike appears.

A graphical weather outlook for the next four days is presented for West Mersea and is based upon the latest run of the ECMWF computer model. Updated twice daily, this forecast provides a view of expected daily weather conditions for the West Mersea area, including predicted minimum and maximum temperatures.


West Mersea Weather History

1940 was a winter of severe weather. The ice was so thick that it was possible to walk across the creeks in West Mersea. The location of the Island of Mersea means that it is particularly susceptible to weather conditions that bring flooding. On 29th November 1897 (often called Black Monday), the tide was so high in West Mersea that houses were often under 3-4 feet of water. Residents took refuge on furniture, and several bed-ridden people had to be moved to safer places. The worst weather event in Essex history was the 1953 flood disaster. Mersea Island was almost completely submerged, and nearly all of the livestock on the Island were drowned or had to be destroyed. The people of Mersea were lauded for their indomitable spirit in the face of such extreme weather conditions, and many stories are still told of bravery and difficulty.


Important: Whilst we provide a comprehensive daily weather forecast service for Essex, we urge visitors to check the Met Office website today for any severe weather warnings and the Environment Agency website for any flood warnings that may affect West Mersea and the surrounding areas.
