.SYNOPSIS...
A mainly light onshore flow has become variable as a weak surface
front moves into the coastal waters and stalls. Behind the front,
a light northerly flow is expected. The front is forecast to
meander over the coastal waters into mid-week before washing out,
with southerly flow again expected to develop over the region
through the remainder of the forecast period. Daily rain chances
early in the period are expected to give way to drier weather by
the end of the period as high pressure develops aloft.
