thunderstorms. The front will enter the southeast Georgia waters
late this afternoon and move through the rest of the coastal
waters tonight. A surge of northerly winds is expected behind the

the area waters beginning on Monday. Winds will decrease and turn

area waters once again. Another cool front will pass through the
waters during the latter part of next week with onshore winds
returning by next weekend.
