... Tropical storm watch remains in effect...

... New information...
Fay has become nearly stationary over the east central Florida
coast. Bands of showers and isolated thunderstorms continue to
increase in coverage... especially from around Edisto
Beach... southward... including the Atlantic waters.

... Areas affected...
this statement recommends specific actions to be taken by
residents and visitors of southeast Georgia.

... Watches/warnings...
the following are in effect for the area...
Flash Flood Watch...

... Storm surge and storm tide...
northeasterly winds are expected to gradually increase through
Thursday... which will help to cause tides to be elevated 1 to 2
feet above normal. Currently... tides are running about 1 foot
above normal. Generally minor beach erosion is expected... with
moderate to major erosion possible on northeast facing shorelines
and beaches. Minor coastal flooding may also be possible if tides
become elevated closer to 2 feet above normal predicted
levels... mainly during periods of high astronomical tides.

... Rip currents...
there will be an elevated risk for rip currents along the beaches
of north coastal Georgia through Friday.

... Winds...
northeast winds will gradually increase... especially tonight into
Thursday as Fay approaches the northeast Florida coast. Winds
could possibly reach minimal tropical storm force along the north
Georgia coast... reaching 30 to 35 mph... with higher gusts of 40 to
45 mph possible... especially near the coasts of Liberty and
McIntosh counties. Lower winds are expected farther
inland... including the Savannah Metro area. However winds could
gust in excess of 40 mph anywhere across the region this afternoon
through Thursday night as squalls move onshore.

Winds of this magnitude are capable breaking small to moderate
size tree limbs... which could fall on power lines. Saturated soils from
heavy rains experienced over the past few weeks may also increase
the risk for downed small trees and power lines.

... Inland flooding...
bands of showers and thunderstorms will continue to develop over
the outer fringes of the circulation of Fay. The heaviest showers
and thunderstorms are expected to be mainly from this afternoon
through Thursday afternoon. Rainfall totals of 2 to 4 inches are
possible... with isolated higher amounts. Minor flooding will be
possible with these rainfall amounts. Some locations near downtown
Savannah have already received up to 2 inches of rain today.

Levels on area rivers remain very low... with some rises likely
through the weekend. However... the risk for river flooding... at
least through Friday... is still low.

... Tornadoes...
there continues to be a risk for isolated tornadoes across the
region this afternoon into Friday morning as bands of showers and
isolated thunderstorms move rapidly across the area.

... Next update...
the next Tropical Storm Fay intermediate local statement will be
issued by the National Weather Service in Charleston around
5 PM or sooner if conditions warrant.

Additional information can be found in advisories issued by the
National Hurricane Center... as well as public information
statements and short term forecasts issued by this office.
