Weather Situation
Fresh south to southwesterly airflow will continue today in the wake of a cold front moving across the Tasman Sea. Winds are expected to ease and tend west to southwesterly over the weekend as a high pressure ridge moves over the region. The high is forecast to enter the Tasman Sea during Monday, turning the winds northerly ahead of the next cold front crossing the coastal waters during mid next week.
