The Far South Coast RFS unit is asking residents to refrain from burning until the winds forecast for the remainder of the week have eased.
The Bureau of Meterology issued severe weather warnings including damaging winds for people in the South Coast for Thursday, July 11.
A Narooma RFS spokeswoman said she had concerns for fires previously lit that had not been completely extinguished.
A Batemans Bay Marine Rescue spokesman said a strong wind warning make it dangerous for any water activity at the Batemans Coast.
Eurobodalla RFS said there would be strong winds and low relative humidity from Thursday, July 11 to at least Sunday, July 14.
"Ongoing dry conditions combined with frost cured grasslands have resulted in a number of grass fires over recent weeks and brigades have done well to catch these fires before they became too large," the RFS said.
"The winds and dry air forecast for the rest of the week have the potential to make fire fighting a much more difficult task.
"In light of the most recent weather forecasts, we are asking that people not only refrain from burning, but that they also check on any piles they have burnt recently to ensure they are fully extinguished."
