NWS National Hurricane Center Miami FL AL042021
500 AM EDT Tue Jun 29 2021

Surface observations indicate that the low-level circulation
associated with Danny is no longer well-defined. Therefore, Danny is
no longer classifiable as a tropical cyclone. The observations also
indicated that the maximum winds associated with these remnants
have decreased to 20 kt or less, while surface pressures have risen
to 1019 mb. The remnants of Danny are moving west-northwestward at
about 15 kt and this general motion is expected to continue through
today, with locally heavy rainfall spreading across portions of
northern Georgia and Alabama.

This is the last NHC advisory on Danny. For additional information
specific to your area, please refer to products issued by your local
National Weather Service Forecast Office.

Key Messages:

1. Heavy rainfall from the remnants of Danny may produce isolated
flash flooding, especially in urban areas, across western and
northern Georgia into central and northern Alabama today.

Tropical Depression Danny Discussion Number 3
NWS National Hurricane Center Miami FL AL042021
1100 PM EDT Mon Jun 28 2021

Danny made landfall just north of Hilton Head on Pritchards Island,
South Carolina, around 2330 UTC with maximum winds of about 35 kt.
Since then, the storm moved inland across extreme southern South
Carolina and is now located over east-central Georgia. Surface
observations and Doppler radar data indicate that Danny has
weakened, and the cyclone has now been downgraded to a 30-kt
tropical depression. Heavy rains associated with the depression
are spreading westward across central Georgia.

The weakening cyclone is moving west-northwestward at about 13 kt.
This general motion is expected to continue overnight and Tuesday
taking Danny, or its remnants, across Georgia and northern Alabama.
As the system continues its trek inland, additional weakening is
forecast, and Danny will likely dissipate by late Tuesday.


Key Messages:

1. Heavy rainfall is possible from coastal southern South Carolina
and Georgia, inland across the Piedmont of Georgia into northeast
Alabama. Isolated flooding is possible across urban areas of the
southern South Carolina and Georgia coasts.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Edisto Beach to South Santee River South Carolina

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Tropical Storm Danny was
located near latitude 32.3 North, longitude 80.5 West. Danny is
moving toward the west-northwest near 16 mph (26 km/h) and this
general motion is expected to continue during the next day or so.
On the forecast track, Danny will move inland across southern South
Carolina and east-central Georgia tonight and early Tuesday morning.

Data from NOAA Doppler radars, earlier reconnaissance aircraft, and
surface observations indicate that maximum sustained winds are near
40 mph (65 km/h) with higher gusts. Rapid weakening is forecast,
and Danny is expected to weaken to a tropical depression later
tonight and dissipate by late Tuesday.

Tropical-storm-force winds extend outward up to 35 miles (55 km)
from the center. A wind gust of 34 mph (55 k/h) was recently
reported at Beaufort Airport in South Carolina.

The minimum central pressure based on surface observations is
estimated to be 1010 mb (29.82 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Danny can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44
KNHC and on the web at
www.hurricanes.gov/graphics_at4.shtml?key_messages.

WIND: Tropical storm conditions are expected to continue in the
warning area during the next few hours.

RAINFALL: Danny could produce 1 to 3 inches of rainfall with
locally higher amounts along the immediate coasts of Georgia and
southern South Carolina. This region has been dry, limiting
potential widespread flooding impacts, however, local flooding
impacts, especially in urban areas along the southern South Carolina
and Georgia coasts, cannot be ruled out at this time.

Farther inland, 1 to 2 inches of rainfall is possible across Upstate
South Carolina, the Piedmont of Georgia, and into northeastern
Alabama.

STORM SURGE: The combination of storm surge and the 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...

Port Royal Sound, SC to South Santee River, SC...1 to 3 ft

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.

TORNADOES: An isolated tornado will be possible this evening along
the South Carolina coast.

Tropical Storm Danny Discussion Number 2
NWS National Hurricane Center Miami FL AL042021
500 PM EDT Mon Jun 28 2021

Deep convection has exploded this afternoon over the center of what
is now Tropical Storm Danny. Reconnaissance aircraft measured 49 kt
winds at the 850-mb fight-level, which equals roughly a 39-kt
surface wind. In addition, Doppler velocity data from the Charleston
radar measured average velocities of 49 kt at 6000-7000 ft, which
also equate to about 40-kt surface winds. A reconnaissance aircraft
dropsonde also measured a central pressure of 1009 mb. Based on
these data, the advisory intensity has been increased to 40 kt.

The initial motion estimate is 290/14 kt. Tiny Danny is forecast to
maintain a west-northwestward motion for the next day or so, with
landfall expected along the southern coast of South Carolina likely
occurring by 0000 UTC this evening. The small tropical cyclone
should continue to move inland across southern South Carolina and
eastern Georgia tonight and early Tuesday, with dissipation expected
over the mountains of northern Georgia by Tuesday night or early
Wednesday. The new NHC track forecast is a little to the left of
the previous advisory track, and lies close to the consensus track
models HCCA, TVCA, and GFEX.

No additional strengthening is anticipated before Danny makes
landfall. Rapid weakening should commence shortly after landfall,
with Danny likely becoming a remnant low by Tuesday morning.
The official intensity forecast follows a blend for the Decay-SHIPS
statistical model for inland tropical cyclones, and the intensity
consensus models IVCN and HCCA.

Key Messages:

1. Heavy rainfall is possible from coastal southern South Carolina
and Georgia, inland across the Piedmont of Georgia into northeast
Alabama. Isolated flooding is possible across urban areas of the
southern South Carolina and Georgia coasts.

2. Tropical-storm-force winds are expected across portions of
the South Carolina coast late this afternoon and tonight where a
Tropical Storm Warning is in effect.

3. Swells generated by Tropical Storm Danny are expected to affect
portions of the South Carolina coast through tonight. These swells
could cause life-threatening surf and rip currents.

and southern South Carolina. This region has been dry, limiting
potential widespread flooding impacts, however, local flooding
impacts, especially in urban areas along the southern South Carolina
and Georgia coasts, cannot be ruled out at this time.

Farther inland, 1 to 2 inches of rainfall is possible across Upstate
South Carolina, the Piedmont of Georgia, and into northeastern
Alabama.

STORM SURGE: The combination of storm surge and the 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...

Port Royal Sound, SC to South Santee River, SC...1 to 3 ft

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.

Tropical Depression Four Discussion Number 1
NWS National Hurricane Center Miami FL AL042021
1100 AM EDT Mon Jun 28 2021

The area of disturbed weather and associated low pressure system
that the NHC has been tracking the past couple of days has developed
into a tropical depression off the coast of South Carolina this
morning. The inner-core cloud structure noted in high-resolution
visible satellite imagery has continued to tighten up and deep
convection with cloud top temperatures of -60 deg C have persisted
northwest through southwest of the center, yielding a Dvorak shear
pattern intensity estimate of 30 kt. This intensity estimate is
consistent with overnight scatterometer surface wind data of 31-32
kt just north of the well-defined center.

The initial motion estimate is 300/14 kt. The small tropical cyclone
is expected to maintain a west-northwestward to northwestward motion
for the next couple of days, resulting in landfall along the
south-central coast of South Carolina later this evening. The small
cyclone is expected to dissipate by 48 hours, if not sooner, when
the system will be located over the southern Appalachian Mountains.
The NHC track forecast lies close to the tightly packed GFS- and
ECMWF-based Beta-Advection models due to the lack of any significant
inner-core convection, which is allowing the cyclone to be steered
more by the low-level flow rather than the deep-layer flow as
depicted by the global and regional models.

There is a narrow window of opportunity this afternoon for the
depression to strengthen into a tropical storm before landfall
occurs. During the next few hours, the small cyclone will be passing
over the warmer Gulf Stream where sea-surface temperatures are
around 28 deg C. In addition, as the outer wind field begins to
interact with land, low-level frictional convergence along and just
offshore should help to generate deep convection just prior to
landfall, helping to spin up the wind field. The NHC forecast shows
the system becoming a tropical storm before landfall, and as a
result a tropical storm warning has been issued for a portion of
the South Carolina coast.

An Air Force Reserve Unit reconnaissance aircraft will investigate
the system this afternoon beginning around 1800 UTC, providing more
detailed information on the cyclone's intensity.

Key Messages:

1. Heavy rainfall is possible from coastal southern South Carolina
and Georgia, inland across the Piedmont of Georgia into northeast
Alabama. Isolated flooding is possible across urban areas of the
southern South Carolina and Georgia coasts.

2. Tropical-storm-force winds are expected across portions of
the South Carolina coast late this afternoon and tonight where a
Tropical Storm Warning is in effect.

3. Swells generated by the depression are expected to affect
portions of the South Carolina coast this afternoon and tonight.
These swells could cause life-threatening surf and rip currents.
