Sea water and spray swept across both lanes in some sections and caused flooding before the tide receded and roads were re-opened. Victoria Avenue was also closed to traffic for the high tide on Friday night.
Strong southerly winds of Force 7 to gale Force 8 were expected to veer west mid-morning and decrease to fresh Force 5 to strong Force 6 later. Fair or sunny periods are forecast with occasional showers, and a risk of hail and thunder.
The flooding along the south coast at high tides followed a freak hailstorm on Friday afternoon as the Island continued to be battered by severe weather.
Traffic briefly ground to a halt and pedestrians were forced to take shelter as hailstones – some the size of marbles – pelted the Island.
It came after the Jersey Met Office had issued a ‘red’ wind warning – the highest level of alert – and predicted a weekend of more storms.
As the bad weather rolled in, Alderney recorded 87 mph gusts, with 75 mph winds being recorded in Jersey.
The States Police received reports of fallen trees in Ville L’Emphrie in St Lawrence, Grande Route de St Jean near MotorMall and Le Profonde Rue in Trinity.
Mark Le Cornu, a duty forecaster at the Met Office, said: ‘With the big tides that we’ve got at the moment people would do well to stay away from promenades on the south coast. There will be quite a bit of spillage there and perhaps some localised flooding.’
