DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Idalia was
located over southeastern Georgia near latitude 32.2 North,
longitude 81.7 West. Idalia is moving toward the northeast near 21
mph (33 km/h), and this general motion is expected to continue
through tonight. A generally eastward motion is forecast to begin
on Thursday and continue through Saturday. On the forecast track,
the center of Idalia will move near or along the coasts of Georgia
and South Carolina through tonight, and then just offshore the
coast of North Carolina on Thursday. Idalia will then move
eastward over the western Atlantic into the weekend.

NOAA Doppler radar data indicate that maximum sustained winds have
decreased to near 70 mph (110 km/h) with higher gusts. Some
additional weakening is forecast through tonight, but Idalia is
expected to remain a tropical storm while it moves near the coasts
of Georgia, South Carolina, and North Carolina.

Tropical-storm-force winds extend outward up to 205 miles (335 km)
from the center. A sustained wind of 52 mph (83 km/h) and a gust
to 67 mph (107 km/h) were recently reported at the Savannah
Entrance Light.

The estimated minimum central pressure is 984 mb (29.06 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Idalia can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC,
and on the web at hurricanes.gov/text/MIATCDAT5.shtml

STORM SURGE: The combination of storm surge and tide will cause
normally dry areas near the coast to be flooded by rising waters
moving inland from the shoreline. The water could reach the
following heights above ground somewhere in the indicated areas if
the peak surge occurs at the time of high tide...

Savannah River to South Santee River, SC...3-5 ft
Saint Catherines Sound, GA to Savannah River...2-4 ft
Beaufort Inlet, NC to Ocracoke Inlet, NC...2-4 ft
Neuse and Bay Rivers...2-4 ft
Pamlico and Pungo Rivers...2-4 ft
South Santee River, SC to Beaufort Inlet, NC...1-3 ft
Ochlockonee River, FL to East Cape Sable, FL...1-3 ft
Tampa Bay...1-3 ft
Charlotte Harbor...1-3 ft
Flagler/Volusia County Line, FL to Saint Catherines Sound, GA...1-3
ft
Ocracoke Inlet, NC to Duck, NC...1-3 ft

The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by large waves.
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For
information specific to your area, please see products issued by
your local National Weather Service forecast office.

WIND: Tropical storm conditions are occurring within the tropical
storm warning area along the northeastern coast of Florida,
Georgia, and South Carolina, and will spread across coastal
sections of North Carolina tonight through Thursday.

RAINFALL: Idalia is expected to produce a swath of 4 to 8 inches of
rainfall with isolated maxima up to 10 inches from east-central
Georgia through central to eastern South Carolina and eastern North
Carolina into Thursday. These rainfall amounts will lead to areas
of flash, urban, and moderate river flooding, with considerable
impacts. The trailing moisture band from Idalia has the potential
to produce additional rainfall amounts of 1 to 2 inches across the
west coast of Florida.

SURF: Swells generated by Idalia along the eastern and central Gulf
coast will subside tonight and Thursday. Swells will affect the
southeastern U.S. coast during the next few days. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

TORNADOES: A few tornadoes will be possible through this evening
across coastal South Carolina and through tonight across southern
coastal North Carolina.
