Jersey Met is upgrading it forecasting service to show the latest wind direction on an hourly basis according to the States of Jersey who fund the island service.
The Met Office says improvements to its existing wind and weather map have been made in response to customer feedback.
The new maps launched on 4 May and feature 49 images every hour for three regions: The English Channel, Channel Islands and the Bay of St Malo.
The island computer system gathers data from a number of UK Met Office weather and wave models and displays the information on a map.
Principal Forecaster John Searson said the improved service would be useful to Channel Islanders for planning sailing or sea activities, but would also come in handy for people planning a beach trip or a ferry crossing and who want to know the likely conditions.
He said “It’s important to stress that the maps must be used in conjunction with the Channel Islands Shipping Forecast – the official forecast for Channel Island waters. Jersey Met forecasters carefully analyse many computer models to make sure they are consistent with real weather and use their experience to adjust the shipping forecast and issue wind warnings based on much more detail, which in turn keeps the community safe.”
