A Status Yellow gale warning is in place for all Irish coastal waters and the Irish Sea as Storm Dennis sweeps towards Britain this weekend.

Winds of up to Force 9 are expected around the coast, while counties Wexford and Waterford are bearing the brunt with gusts of up to 120km/m.

Difficult weather conditions are forecast by Met Éireann to last until Monday (17 February).

Storm Dennis has already prompted the cancellation of DMYC Frostbite dinghy races tomorrow (Sunday 16 February) due to strong gusts predicted for Dun Laoghaire Harbour.

However, the DBSC said it would make every effort to sail the Spring Chicken series in the morning.
